1 Understanding the Migration Process

This chapter provides an overview of migration from Oracle Warehouse Builder (OWB) to Oracle Data Integrator (ODI).

The following topics are addressed here:

- About Migration

- About the Migration Utility

- What Is and Is Not Migrated

- Roadmap for Migrating

About Migration

ODI is Oracle's strategic product for heterogeneous data integration. Because many Oracle Database customers have significant investment in OWB, Oracle supports a phased migration from OWB 11gR2 (11.2.0.4) to ODI 12c (12.1.2). The following features are provided to make the transition to ODI easier:

- ODI 12c supports the execution and administration of OWB 11gR2 jobs directly within ODI Studio and ODI Console, providing a single orchestration and monitoring solution. This feature enables you to migrate OWB objects over a longer period of time and in a way that makes sense for your business. For more information about this feature, see "OdiStartOwbJob" in the tools reference section of the Developer's Guide for Oracle Data Integrator.

- ODI 12c supports an easier mapping between OWB 11gR2 concepts and objects and their ODI 12c counterparts. A migration utility is provided that automatically translates many OWB objects and mappings into their ODI equivalents. For more information about the migration utility, see About the Migration Utility.

About the Migration Utility

The migration utility is a command-line tool that enables you to migrate design-time metadata from OWB to ODI. Runtime data and physical objects are not migrated. The migration utility uses the settings in the migration utility configuration file to perform the migration.

For information about obtaining the patch, see Migration Requirements.

What Is and Is Not Migrated

The migration utility is an aid to migration only, and not all types and variants of OWB objects are migrated. Manual effort should be expected as well.

2 Preparing to Migrate

This chapter lists migration requirements and describes how to create the configuration file used for migration.

The following topics are addressed here:

- Migration Requirements

- Creating the Migration Utility Configuration File

Migration Requirements

Migration is supported on Linux and Windows 64-bit x86 systems only. Before migrating, ensure that the following requirements are met:

- OWB 11.2.0.4 installed (OWB 11.2.0.4 plus patch number 17830453)

- ODI 12.1.2.0.0 installed with both of the following:

- Patch number 17053768

- ODI 12.1.2.0.1 bundle patch (patch number 17836908)

- OWB workspace exists

- ODI repositories exist

- ODI_HOME and JAVA_HOME environment variables set. The ODI_HOME variable should be set to the ODI installation directory, such as /home/oracle/Middleware. The JAVA_HOME variable should be set to the JDK installation directory, such as /java/jdk1.7.0_25/.

- Migration utility configuration file created

Also ensure that you have the following information:

- ODI master repository password

- ODI user password

- OWB workspace owner password

- Full path to the migration utility configuration file and the file name

Note:

Download the required patches from My Oracle Support (https://support.oracle.com). Apply the patches using the instructions in the patch readme files.

Creating the Migration Utility Configuration File

Before migrating, you must first create the configuration file used to perform the migration. The configuration file is a text-based properties file that contains connection information and other details.

The following topics are addressed here:

- To Create the Migration Utility Configuration File

- Configuration File Parameters

- Configuration File Example

To Create the Migration Utility Configuration File

A template file is provided to make creation of the migration utility configuration file easier. Use this template as your starting point and edit the settings to fit your specific environment and needs.

The template file is named migration.config and is located in the OWB_HOME/bin/admin directory, where OWB_HOME is your OWB installation directory.

To create the migration utility configuration file:

1. Open the migration.config file in a text editor.

2. Edit the settings to fit your specific environment and needs. For more information about each parameter, see Configuration File Parameters.

3. Save the file. The file can be named whatever you like and saved to the location of your choice.
Make note of the file name and its path, because you will need this information when you run the migration utility.

Configuration File Parameters

Table 2-1 lists the parameters in the migration utility configuration file.

Table 2-1 Migration Utility Configuration File Parameters

Parameter

Mandatory

Description

ODI_MASTER_USER=<user_name>

Yes

User name for the ODI master repository connection.

ODI_MASTER_URL=<JDBC_URL>

Yes

JDBC URL used to connect to the ODI master repository. This URL must be quoted if it contains one of the following characters:

- semicolon (;)

- backslash (\)

- double quote (")

- back quote (`)

- dollar sign ($)

- less than (<)

- greater than (>)

The default value is jdbc:oracle:thin:@localhost:1521:mydb

ODI_MASTER_DRIVER=<JDBC_driver_name>

Yes

JDBC driver used to connect to the ODI master repository.

The default value is oracle.jdbc.OracleDriver

ODI_USERNAME=<user_name>

Yes

Supervisor user name for ODI.

The default value is SUPERVISOR.

ODI_WORK_REPOSITORY_NAME=<user_name>

Yes

User name used to connect to the ODI work repository.

The default value is WORKREP1.

OWB_WORKSPACE_OWNER=<workspace_owner>

Yes

OWB workspace owner.

OWB_URL=<URL>

Yes

URL used to connect to the OWB workspace.

The default value is localhost:1521:mydb

OWB_WORKSPACE_NAME=<workspace_name>

Yes

Name of the OWB workspace to connect to, specified in one of the following formats:

- Workspace owner and workspace name, separated by a period. For example, REP_1.WS1 or rep_1.ws1.

- Workspace name only. For example, WS1 or ws1.

The migration utility can be used to migrate just one workspace at a time. Edit this parameter (and others as necessary) and run the migration utility for each workspace that you want to migrate.

If the workspace owner owns just one workspace, you do not need to specify this parameter.

If the workspace owner owns multiple workspaces and no value is specified for this parameter, an error is returned. If a workspace has the same name as the workspace owner, the workspace is migrated.

If the specified workspace does not exist, the connection fails.

MIGRATION_LOG_FILE=<path_to_log_file>

No

Full path to the migration utility log file, which is generated when you run the migration utility.

The migration utility exclusion report is also generated, and uses the same prefix as the log file, with a .report extension.

This parameter is used to specify the name and location for both the log file and the report file. If no path is specified, the log and report files are generated in the same directory from which the migration utility was executed, for example, OWB_HOME/owb/bin/unix. By default, the file names are migration.log and migration.report.

For more information about these files, see Reviewing Log and Report Files.

MIGRATION_REPORT_INCLUDE=<PASSED|FAILED|ALL>

No

Content to be included in the migration utility exclusion report. Options are:

- PASSED: Include only objects that succeeded.

- FAILED: Include only objects that failed.

- ALL: Include all objects.

The default value is ALL.

MIGRATION_MODE=<FAST_CHECK|DRY_RUN|RUN>

No

Migration mode. Options are:

- FAST_CHECK: The migration utility performs a quick check for selected objects and provides a report that lists objects that can and cannot be migrated to the target ODI repository. Use this mode to quickly determine which objects can and cannot be migrated.

- DRY_RUN: The migration utility checks whether the specified objects can be created in the target ODI repository, and executes the migration without committing the objects to the repository. This mode provides more information than FAST_CHECK. Use this mode to more completely determine which objects can and cannot be migrated.

- RUN: The migration utility executes the migration and commits migrated objects to the target ODI repository. Use this mode to perform the migration from OWB to ODI.

The default value is RUN.

For more information about using the FAST_CHECK and DRY_RUN modes to perform a test migration, see Performing a Test Migration.

MIGRATE_DEPENDENCIES=<TRUE|FALSE>

No

Controls whether dependent objects are migrated with the objects selected for migration.

The default value is FALSE (dependent objects are not migrated).

Recursive dependency is supported when MIGRATE_DEPENDENCIES is set to TRUE. For example:

Mapping MAP_1 has a map operator bound to table T_1, and table T_1 has an FK (foreign key) relationship with table T_2. Both T_1 and T_2 are considered as dependencies and are migrated along with mapping MAP_1.

STOP_ON_ERROR=<TRUE|FALSE>

No

Indicates whether to continue the migration process or stop when an error occurs.

When set to TRUE, the migration process stops and no objects are migrated. When set to FALSE, the migration process continues even if an error occurs, and successful objects are migrated.

The default value is FALSE.

SPLIT_JOIN_FOR_ANSI_SYNTAX=<TRUE|FALSE>

No

Indicates whether to split the join operator to binary join when the property Use ANSI Syntax of the OWB mapping is set to TRUE.

The default value is TRUE (join operator is split).

MIGRATE_UNBOUND_OPERATOR=<TRUE|FALSE>

No

Determines whether mappings that contain unbound operators (excluding Code Template mappings) are migrated. Unbound operators include external table, table, view, materialized view, lookup, and pluggable mapping.

When set to TRUE, mappings that contain unbound operators are migrated. For unbound entity operators (external table, table, view, materialized view, and lookup), an ODI datastore corresponding to the unbound operator is created in the ODI model that is migrated from the OWB module where the OWB mapping exists. The unbound operator is migrated to an ODI mapping component bound to the newly created ODI datastore.

For an unbound pluggable mapping operator, an ODI reusable mapping is created in an ODI folder named STAND_ALONE. The unbound pluggable mapping operator is migrated to the ODI reusable mapping component bound to the newly created reusable mapping.

The default value is FALSE, which means any mappings that contain unbound operators are not migrated.

MIGRATION_OBJECTS=<objects>

No

Specifies the OWB objects to be migrated.

The default value is the wild card asterisk (*), which means that all projects in the designated OWB workspace are migrated.

For more information about migrating specific objects, see Migrating Specific Objects in an OWB Workspace.

FLUSH_BATCH_SIZE=<number_of_mappings>

No

Indicates the number of mappings to be processed or migrated at a time.

Use this parameter to avoid out of memory issues if the OWB workspace has a very large number of mappings.

The default value is 50. Reduce this value if out of memory issues occur.

Configuration File Example

This example shows values for a sample migration utility configuration file.

3 Using the Migration Utility to Migrate

This chapter describes how to use the migration utility to migrate objects from OWB to ODI.

Migration is performed using the settings specified in the migration utility configuration file. For more information about this file, see Creating the Migration Utility Configuration File.

Note:

The OWB workspace and the ODI repository should not be in use when you run the migration utility and perform the migration.

The following topics are addressed here:

- Migration Utility Syntax and Parameters

- Migrating an OWB Workspace

- Migrating Specific Objects in an OWB Workspace

- Performing a Test Migration

Migration Utility Syntax and Parameters

The migration utility is started from the command line and takes several parameters as inputs to perform the migration.

The migration utility file is named migration.sh and is executed from the OWB_HOME/owb/bin/unix directory, where OWB_HOME is your OWB installation directory.

The syntax to run the migration utility and perform the migration is as follows:

./migration.sh <odi_master_password> <odi_user_password> <owb_workspace_owner_password> <configuration_file>

For example:

./migration.sh odi_master supervisor migration /scratch/jsmith/Migration/owb_migration.properties

The command parameters are as follows:

- odi_master_password: ODI master repository password

- odi_user_password: ODI user password

- owb_workspace_owner_password: OWB workspace owner password

- configuration_file: Full path to the migration utility configuration file and the file name

See Also:

For more information about the migration modes used to test and perform the migration, see MIGRATION_MODE in Configuration File Parameters.

After migration is complete, you are returned to the command prompt. You can then review the migration utility log file and exclusion report for details about the migration. For more information about these files, see Reviewing Log and Report Files.

Migrating an OWB Workspace

To migrate an entire OWB workspace, use the wild card asterisk (*) as the value for the MIGRATION_OBJECTS parameter in the migration utility configuration file. For example:

MIGRATION_OBJECTS=*

All projects and supported objects in the OWB workspace specified by the OWB_WORKSPACE_NAME parameter in the configuration file will be migrated.

Note:

You can migrate just one workspace at a time. Edit the configuration file and run the migration utility for each workspace that you want to migrate.

Migrating Specific Objects in an OWB Workspace

To migrate specific objects in an OWB workspace, configure the MIGRATION_OBJECTS parameter in the migration utility configuration file to migrate just those objects. You can specify a project, folder, or single non-folder object, or a set of objects that share the same type and the same folder.

Use a string that concatenates the qualifying names of all objects included in the object's path, from the top-level object to the leaf object. Qualifying names are specified as OBJECT_TYPE.OBJECT_PHYSICAL_NAME, with a period (.) separating the object type from its physical name. For example, to select table T_1 in Oracle module MOD_1 in project PRO_1, set the value of the MIGRATION_OBJECTS parameter to PROJECT.PRO_1.MODULE.MOD_1.TABLE.T_1.

The following values can be used for OBJECT_TYPE:

- EXTERNAL_TABLE

- FLAT_FILE_MODULE

- FLAT_FILE

- GENERIC_FOLDER

- GENERIC_MODULE

- LOCATION

- MODULE

- MAPPING

- MATERIALIZED_VIEW

- PLUGGABLE_MAPPING

- PLUGGABLE_MAPPING_FOLDER

- PROJECT

- SAP_MODULE

- SEQUENCE

- TABLE

- VIEW

Use a semicolon (;) to separate multiple items, for example:

MIGRATION_OBJECTS=PROJECT.PRO_1.MODULE.MOD_1.TABLE.T_1;PROJECT.PRO_2.MODULE.MOD_2;

Use a backslash (\) at the end of a line to improve readability of the configuration file if there are multiple items, for example:

MIGRATE _OBJECTS=
PROJECT.OWB_MIGRATION.SAP_MODULE.MY_SAP_MOD;\
PROJECT.MY_PROJECT.MODULE.ORA_MOD;\
PROJECT.MY_PROJECT.MODULE.DB2_MOD

Use the wild card asterisk (*) at the end of a string instead of an object name to select all objects of a specific type in a folder. The following example selects all tables in module MOD_1:

MIGRATION_OBJECTS=PROJECT.PRO_1.MODULE.MOD_1.TABLE.*

Use the wild card asterisk (*) at the end of an object name to select all objects with that name. The following example selects all tables in module MOD_1 with a name that starts with MYTEST:

MIGRATION_OBJECTS=PROJECT.PRO_1.MODULE.MOD_1.TABLE.MYTEST*

The following uses are not supported:

MIGRATION_OBJECTS=PROJECT.*.MODULE.MOD_1.TABLE.T_1;
MIGRATION_OBJECTS=PROJECT.PRO_1.MODULE.*.TABLE.T_1;
MIGRATION_OBJECTS=PROJECT.*.MODULE.*.TABLE.*;
MIGRATION_OBJECTS=PROJECT.PRO_1.MODULE.*.TABLE.MYT*;
MIGRATION_OBJECTS=PROJECT.PRO_1.MODULE.MYMOD*.TABLE.MYT_1;

When an invalid object is specified, an error is returned:

[ERROR][Migration][MU-1005] The selected object {0} does not exist or the
selection is invalid. It will be skipped.

For more information about error messages that you might encounter when you run the migration utility, see Error Message Reference.

Example 3-1 Migrating Specific Objects

This section provides additional examples of migrating specific objects.

The following example migrates Oracle Database module ORACLE_EBS_D in project SSAD:

MIGRATION_OBJECTS=PROJECT.SSAD.MODULE.ORACLE_EBS_D;

The following example migrates pluggable mapping DEBS_EDW_MAP1 in pluggable mapping folder DWPR_SUB:

MIGRATION_OBJECTS=PROJECT.PROJ_DW.PLUGGABLE_MAPPING_FOLDER.DWPR_SUB.PLUGGABLE_MAPPING.DEBS_EDW_MAP1;

The following example migrates standalone pluggable mapping PLUGGABLE_MAPPING_1 in project SSA:

MIGRATION_OBJECTS=PROJECT.SSA.PLUGGABLE_MAPPING.PLUGGABLE_MAPPING_1

Performing a Test Migration

To test your migration before executing it, set the MIGRATION_MODE parameter in the migration utility configuration file to FAST_CHECK or DRY_RUN.

The FAST_CHECK option checks which objects can and cannot be migrated. The DRY_RUN option checks whether the specified objects can be created in the target ODI repository, and executes the migration without committing the objects to the repository. For more information about these options, see MIGRATION_MODE in Configuration File Parameters.

After performing a test migration, review the migration utility log file and exclusion report for details. You can use these files to identify objects that can and cannot be migrated and to address any issues before performing the actual migration. For more information about these files, see Reviewing Log and Report Files.

4 Reviewing Your Migration

This chapter describes how to review and verify your migration.

The following topics are addressed here:

- Reviewing Log and Report Files

- Verifying Your Migration

Reviewing Log and Report Files

Two files are created after migration is complete or after you perform a test migration. By default, the files are named migration.log and migration.report. Use these files to review, refine, and troubleshoot your migration.

By default, the files are saved in the same location as the migration utility configuration file. You can specify a different file name and location using the MIGRATION_LOG_FILE parameter in the configuration file. For more information about this parameter, see MIGRATION_LOG_FILE in Configuration File Parameters.

The following topics are addressed here:

- Reviewing the Migration Utility Log File

- Reviewing the Migration Utility Exclusion Report

Reviewing the Migration Utility Log File

The migration utility log file contains details about objects that were migrated, and error messages if any errors occurred.

The log file is organized in the following sections:

- Log file header with migration mode, log file creation time, OWB and ODI details, and full path to the log file.

- Migration start time.

- Detailed information about the migration status of each object (whether migration succeeded or failed) and error messages if errors occurred. For more information about error messages that you might encounter when you run the migration utility, see Error Message Reference.

- Summary information organized by object type, including the path to each object.

- Log file footer with total execution time and migration end time.

Reviewing the Migration Utility Exclusion Report

The migration utility exclusion report contains a summary of the objects migrated, and lists whether migration succeeded or failed for each object.

The exclusion report is organized in the following sections:

- Exclusion report header with migration mode, report creation time, OWB and ODI details, and full path to the report file.

- Migration start time.

- Migration statistics including how many projects were migrated, and total number of objects migrated for each project.

- Detailed migration status for each selected object (whether migration succeeded or failed).

- Exclusion report footer with total execution time and migration end time.

Verifying Your Migration

When migration is complete, perform the following steps in ODI to verify the mappings that were migrated from OWB:

- Use ODI Studio to connect to the ODI environment. See "Connecting to a Work Repository" in the Developer's Guide for Oracle Data Integrator.

- Navigate to Topology Navigator and review the data server settings. You may need to edit some of the information such as user names, passwords, or JDBC URLs depending on your environment. Test each connection to make sure that each migrated data server is correctly configured. See "Setting Up the Topology" in the Developer's Guide for Oracle Data Integrator.

- Navigate to Designer Navigator and review the migrated models and datastores in the Models panel. See "Creating and Using Data Models and Datastores" in the Developer's Guide for Oracle Data Integrator.

- Navigate to Designer Navigator and verify the migrated mappings in the Projects panel by running the mappings. See "Creating and Using Mappings" in the Developer's Guide for Oracle Data Integrator.

B Reference to Migration Details

This appendix provides reference information about migrating OWB to ODI.

This appendix contains the following topics:

- OWB Repositories

- OWB Data Objects

- OWB Mappings

- OWB Pluggable Mappings

OWB Repositories

OWB Workspace to ODI Work Repository

When invoking the migration utility, the OWB Workspace Owner and its password are needed to connect to the OWB Repository. Each OWB Workspace Owner may have multiple workspaces. Only one workspace will be migrated with each migration. Therefore, one workspace name must be specified for each migration. Each OWB workspace will be migrated to ODI as one ODI Work repository.

If an OWB Workspace owner has multiple OWB Workspaces, each OWB Workspace should be migrated to an ODI Work repository of an ODI Master repository. The migration utility can only migrate at most one OWB Workspace at each time.

OWB Platform to ODI Technology

OWB Platforms and their associated data types are mapped to ODI Technologies and their associated data types. This platform and data type mapping is stored in a configuration file.

For the predefined platforms in OWB, the mappings to ODI can be found in the file PlatformMappingsForMigration.xml located in the <ORACLE_HOME for OWB>/owb/bin/admin directory.

If a user has defined new or custom Platforms in OWB, the mapping of this platform and its data types to ODI technology and its data types can be defined in the same configuration file. The physical name of the OWB Platform should be specified in the mapping, and the internal name of the ODI technology should be used.

The following table shows the predefined OWB Platform to ODI Technology mappings.

OWB Platform

Oracle

DB2UDB

IBM DB2 UDB

SQLSERVER

OBIEE, OBISE, J2EE

These are not migrated.

Data type mapping differs for each OWB Platform mapping. The following tables show the data type mappings for each predefined OWB Platform.

If an OWB data type that has no mapping in ODI is used in Data Objects like Table, View, Materialized View, and External Table, the data object is reported as not migrated.

If an OWB data type that has no mapping in ODI is used in a Mapping Attribute, the data type of the mapping attribute is not set.

OWB Location to ODI Data Server

Each OWB Location is associated with an OWB Platform or equivalent ODI technology. Hence OWB location will be migrated to an ODI Data Server under the equivalent ODI technology.

Location Name to Data Server Name

Location Name will be migrated to ODI Data Server Name. Since OWB Location Name is unique within an OWB Workspace, while ODI Data Server Name is unique within the master repository, when there are several OWB workspaces for a Workspace Owner, each OWB Workspace should be migrated to a different ODI Master repository to avoid name conflicts.

Location Properties to Data Server Properties

The following table shows mapping of properties of OWB Location to properties of ODI Data Server:

Physical Schema and Logical Schema

OWB supported a list of Data Locations for use with a module but only one location is selected to use at a time. This location is called the active location. During migration, only the active location will be migrated to ODI. The location is migrated as ODI Data Server. Corresponding to the location user name, a new ODI Physical Schema will be created in ODI if one does not exist already. The new ODI Physical Schema will be from the Location Schema of OWB Database Location, or the directory path for File Location.

Corresponding to the physical schema, a logical schema will be created in ODI if none with the same name as the Model name exists. The logical schema will set to "LS_" plus model name, and will be associated with the physical schema in the global context.

Strategy

Multiple Target Mapping Migration

For mappings with multiple targets, target load order and Multiple Target Insert (MTI) are considered for migration.

Target Load Order

The OWB Target Load Order property is migrated to the ODI Target Load Order property.

The OWB Use Target Load Ordering property is not migrated, because this property does not exist in ODI.

Multiple Target Insert (MTI)

When an OWB mapping has multiple targets to insert, the data is coming from the same sources, and the Optimized code option is set to true, during code generation, a single insert statement for all targets may be generated instead of a multi-table insert SQL statement.

Because this property is a physical property and MTI occurs at code generation, MTI is not supported for migration.

OWB Pluggable Mappings

OWB Pluggable Mapping is migrated to ODI Reusable Mapping.

Also see Pluggable Mapping Operator.

Pluggable Mapping Folder

The OWB Pluggable Mapping Folder is migrated to an ODI Project Folder. Standalone pluggable mappings are migrated to a Project Folder named STAND_ALONE, which is created automatically during migration if it does not already exist.

Properties of Pluggable Mapping

Only Physical name and Description are migrated. Physical name of OWB Pluggable Mapping is migrated to name of ODI Reusable Mapping. Description of OWB Pluggable Mapping is migrated to Description of ODI Reusable Mapping.

Input Signature and Output Signature

In OWB, Signature Operator can have unlimited attribute groups (for Input Signature Operator, the attribute groups are output groups; for Output Signature Operator, the attribute groups are input groups). In ODI, Signature Component can have only one connector point, so each attribute group of OWB Signature Operator is migrated to a Signature Component.

For example, the following figure shows a Pluggable Mapping for which the INPUT_SIGNATURE operator has three output groups (INGRP1, INGRP2, and INGPR3).

These OWB output groups are migrated to three Input Signature Components in ODI, as shown in the following figure.

The name of ODI Signature Component is composed of OWB attribute group name of Signature Operator, underscore (_), and Signature Operator name.

The attributes of Signature Operator in OWB are migrated to attributes of Signature Component in ODI. No special properties need to be migrated for signature attributes.

Join Operator in Pluggable Mapping

OWB Pluggable Mapping does not have the property ANSI SQL Syntax as does a regular OWB Mapping. Therefore, all Join Operators of a Pluggable Mapping are split into binary joins during migration to ODI unless the migration configuration option SPLIT_JOIN_FOR_ANSI_SYNTAX is set to false in the migration utility configuration file. For information about ordered join, see Join Operator.

Join Operator

The OWB Join operator is migrated to the ODI Join component. Attribute groups and attributes of the OWB Join operator are not migrated.

Properties of the Join Operator

For information about the general properties of the Join operator, see "Mapping Operator".

ANSI SQL syntax

ANSI SQL syntax is a property on the mapping level in OWB.

ODI does not have this property on the mapping level, but the ODI Join component has a property called Generate ANSI Syntax which has the same functionality.

The value of ANSI SQL syntax on the OWB mapping is migrated to the Generate ANSI Syntax property of the ODI Join component.

Join Condition

Join Condition on the OWB Join operator is migrated to Join Condition on ODI Join component. However, the OWB Join Condition references its own operator's input attributes, which is not supported in ODI; thus, the ODI Join Condition is configured to reference the attributes of the upstream sources to the OWB input attribute.

Join Input Role

Join Input Role is an attribute group level property of the OWB Join operator. It has three choices: STANDARD, OUTER and FULLOUTER.

The corresponding property on the ODI Join component is Join Type.

Join Input Role does not map directly to Join Type because Join Input Role supports multiple input groups, while Join Type supports only a binary join. During migration, complex joins are split into a series of the binary joins using the OWB code generation rules for the Join operator.

Migrating an ANSI Join Operator

When ANSI SQL syntax of OWB mapping is set to true, the Join operator is by default split into binary joins during migration.

Setting the SPLIT_JOIN_FOR_ANSI_SYNTAX migration configuration option to false can override this default behavior and prohibit the Join operator from being split into binary joins. However, if a "Join Input Role" value is set on any of the Join operator's attribute groups, the value of the SPLIT_JOIN_FOR_ANSI_SYNTAX migration configuration option is ignored and the Join operator is split into binary joins during migration.

The following scenarios provide examples of migrating the Join operator when ANSI SQL Syntax is set to true for the mapping.

Scenario 1: Two Input Groups with Standard Join

OWB mapping description: two sources joining together, the join condition is standard join (not outer join). No "Join Input Role" is specified on input attribute groups of Join operator.

Join Condition is: INGRP2.DEPTNO = INGRP1.DEPTNO and INGRP1.EMPNO > 1000

The generated code (only displays the select clause) from OWB side is:

SELECT
"EMP"."EMPNO" "EMPNO", "EMP"."ENAME" "ENAME", "DEPT"."DNAME" "DNAME"
FROM
"DEPT" "DEPT" JOIN "EMP" "EMP"
ON ( ( "DEPT"."DEPTNO" = "EMP"."DEPTNO" ) )
WHERE ( "EMP"."EMPNO" > 1000 )

When this kind of mapping is migrated to ODI, the ODI mapping should look as follows:

The join condition for JOIN1 is: ( DEPT.DEPTNO = EMP.DEPTNO )

The filter condition for Filter_JOIN1 is: ( EMP.EMPNO > 1000 )

The operator JOIN1 in OWB mapping is migrated to a Join component followed a Filter component in ODI.

Scenario 2: Two Input Groups with Outer Join Using (+) Style

The mapping is much similar with the mapping in scenario 1. The only difference is the join condition is not a standard join. It is an outer join using (+) style.

JOIN_CONDITION is: INGRP2.DEPTNO(+) = INGRP1.DEPTNO

The generated code (only displays the select clause) from OWB side is:

SELECT
"EMP"."EMPNO" "EMPNO","EMP"."ENAME" "ENAME", "DEPT"."DNAME" "DNAME"
FROM
"DEPT" "DEPT"
RIGHT OUTER JOIN "EMP" "EMP" ON ( ( "DEPT"."DEPTNO" = "EMP"."DEPTNO" ) )

The migrated ODI mapping should look as follows:

The join condition is set to DEPT.DEPTNO = EMP.DEPTNO, and the join type is set to DEPT RIGHT_OUTER join EMP.

Scenario 3: Two Input Groups with Outer Join Using Join Input Role

Two sources joining together, the join condition is standard join, but "Join Input Role" is specified on some of the input attribute groups of Join operator. Take the following OWB mapping as an example:

The Join Input Role of INGRP1 is set to OUTER.

Join condition is: INGRP2.DEPTNO = INGRP1.DEPTNO

The generated code (only displays the select clause) from OWB side is:

SELECT
"EMP"."EMPNO" "EMPNO",
"EMP"."ENAME" "ENAME",
"DEPT"."DNAME" "DNAME"
FROM
"DEPT" "DEPT"
LEFT OUTER JOIN "EMP" "EMP" ON ( ( "DEPT"."DEPTNO" = "EMP"."DEPTNO" ) )

The migrated ODI mapping looks like the following:

The join condition is set to DEPT.DEPTNO = EMP.DEPTNO, and the join type is set to DEPT LEFT_OUTER join EMP.

Scenario 4: Two Input Groups with both (+) Style and Join Input Role

In this case, OWB will use Join Input Role to generate code and ignore the (+) style. The migrated mapping will be the same as Scenario 3.

Scenario 5: Multiple Input Groups

Take the following mapping as an example:

Join condition is:

INGRP1.SAL > 1000 and INGRP1.EMPNO(+) = INGRP2.DEPTNO
and INGRP3.ENAME = INGRP4.CUSTID and INGRP1.EMPNO = INGRP4.CUSTID
and SUBSTR(INGRP1.ENAME(+),0,2) = INGRP2.DNAME

The generated code (only displays the select clause) from OWB side is:

SELECT
/* EMP.INOUTGRP1 */
"EMP"."EMPNO" "EMPNO",
"EMP"."ENAME" "ENAME",
"EMP"."JOB" "JOB",
"EMP"."MGR" "MGR",
"EMP"."HIREDATE" "HIREDATE",
"EMP"."SAL" "SAL",
"EMP"."COMM" "COMM",
"EMP"."DEPTNO" "DEPTNO"
FROM
"EMP" "EMP" ) "INGRP1"
RIGHT OUTER JOIN "DEPT" "DEPT" ON (
(( "INGRP1"."EMPNO" = "DEPT"."DEPTNO" ))
AND (( SUBSTR ( "INGRP1"."ENAME" , 0 , 2 ) = "DEPT"."DNAME" ))
)
JOIN "ADDRESS" "ADDRESS$1" ON ( ( "INGRP1"."EMPNO" = "ADDRESS$1"."CUSTID" ) )
JOIN "BONUS" "BONUS" ON ( ( "BONUS"."ENAME" = "ADDRESS$1"."CUSTID" ) )
WHERE
( "INGRP1"."SAL" > 1000 )

The migrated ODI mapping looks like this:

The properties of JOINER would be:

The properties of JOINER1 would be:

The properties of JOINER2 would be:

The properties of Filter_JOINER would be:

Migrating a Non-ANSI Join Operator

When the property ANSI SQL syntax of OWB mapping is set to false, the OWB Join operator will be migrated to one ODI Join component.

Exception: when "ANSI SQL syntax" is set to false, but "Join input Role" is set for some of the Join operator attribute groups. The OWB Join operator may be split into binary joins as described in "Join Input Role".

Migrating a Self Join

The following mapping is allowed in OWB, but it is not well supported in ODI.

One source table operator is connected to two input groups of the Join operator.

To support this mapping, the source table operator is migrated twice, producing an ODI mapping like:

Lookup Operator

The OWB Lookup operator is not migrated to ODI directly. Instead, each of its input/output attribute group pairs is migrated to an ODI Lookup component.

If the OWB Lookup operator has multiple input/output attribute group pairs, the resulting ODI Lookup components are chained together as a binary tree.

Properties of the input/output attribute group pairs are migrated to properties of the ODI Lookup components.

Mapping Input Parameter Operator

Each attribute of an OWB Mapping Input Parameter operator is migrated as one ODI variable under the project tree panel.

The default value of an attribute in the OWB Mapping Input Parameter operator is migrated as the default value of the ODI variable. If the default value is not set, the expression of the attribute is used instead.

By default, the attribute name is migrated to the ODI variable name. If the name already exists, a number is automatically appended to create a unique name. If multiple attributes of the same name are migrated, increasing numbers are used to create unique names.

Properties of the Attributes of the Mapping Input Parameter Operator

OWB Property Name

ODI Property Name

Description

Physical Name

Name

If the name already exists, a number is automatically appended to create a unique name.

Default Value

Default Value

The default value of the attribute in the OWB Mapping Input Parameter will be migrated as the ODI Variable's default. If the default value of the attribute in the input parameter is not set, use the expression of the attribute instead.

Data Type; one of:

- TIMESTAMP

- TIMESTAMP_WITH_LOCAL_TIME_ZONE

- TIMESTAMP_WITH_TIME_ZONE

- DATE

Data Type: DATE

The attribute's default value (or expression if no default value is set) is converted to text and the ODI variable's data type is configured as SHORT_TEXT or LONG_TEXT:

- If the length of the converted text exceeds 250, the ODI variable's data type is configured as LONG_TEXT.

- Otherwise, the ODI variable's data type is configured as SHORT_TEXT.

Data Type; one of:

- NUMBER

- NUMERIC

- FLOAT

- BINARY_DOUBLE

- BINARY_FLOAT

- INTEGER

Data Type: NUMERIC

If the attribute's default value (or expression if no default value is set) cannot be parsed to numeric, it is converted to text and the ODI variable's data type is configured as SHORT_TEXT or LONG_TEXT:

- If the length of the converted text exceeds 250, the ODI variable's data type is configured as LONG_TEXT.

- Otherwise, the ODI variable's data type is configured as SHORT_TEXT.

Data Type; one of:

- VARCHAR2

- VARCHAR

- CHAR

- NCHAR

- NVARCHAR2

Data Type: SHORT_TEXT

If the length of attribute's default value (or expression if no default value is set) exceeds 250, the ODI variable's data type is configured as LONG_TEXT.

Data Type: Other

Not Supported

If the attribute's type in OWB is some other type, the operator will not be migrated.

Migration Logic

The following diagram provides an example of how the OWB Mapping Input Parameter is migrated to ODI. In this diagram, note the following:

1. Each attribute inside the Mapping Input Parameter EMP_RANGE is migrated to a standalone variable; for example, EMP_RANGE.EMPNO_MIN is migrated to the ODI project variable EMPNO_MIN.

2. The attribute's default value or expression is migrated to the ODI variable's default value; for example, the expression 4001 of EMP_RANGE.EMPNO_MIN in OWB is migrated to the ODI variable EMPNO_MIN's default value of 4001.

3. The downstream expressions of OWB Mapping Input Parameter attributes are parsed to use the variable; for example, the FILTER condition expression has been converted to #OPERATOR_MIGRATION.EMPNO_MIN.

How the Default Value Is Used

Once a mapping that contains an Input Parameter operator been migrated to ODI, it can be executed through the generated mapping scenario. During the execution, all the ODI variables migrated from OWB will be populated with the default value (OWB input parameter attribute's default value or expression). If necessary, you can change the value as needed, as shown in the following figure:

Input attributes of the OWB Pivot operator are not migrated.

Output attributes are migrated. Name, Data Type, Length, Precision, Scale, Second Precision and Description are general properties described in "Mapping Attribute". Migration of the Row Locator property is described in "Row Locator". The Expression property of the OWB Output attribute is migrated to the Expression property of the ODI Output attribute.

Pluggable Mapping Operator

The OWB Pluggable Mapping operator is migrated to the ODI Reusable Mapping component.

For general information about migrating pluggable mappings, see OWB Pluggable Mappings.

Properties of the Pluggable Mapping Operator

No specific properties of the Pluggable Mapping operator need to be migrated.

Attribute Groups and Attributes of the Pluggable Mapping Operator

Attribute groups and attributes in the Pluggable Mapping operator are not migrated.

In ODI, when a Reusable Mapping component is bound to a Reusable Mapping, the connector points and attributes of the Reusable Mapping component are created automatically according to the binding Reusable Mapping. Thus, if an OWB Pluggable Mapping operator is not consistent with its bound object in OWB, migration issues might arise. To avoid any such issues, synchronize the Pluggable Mapping operator before migration.

Migrating an Unbound Pluggable Mapping Operator

A mapping containing an unbound Pluggable Mapping operator will not be migrated unless the MIGRATE_UNBOUND_OPERATOR migration configuration option is set to true.

During migration, a Reusable Mapping will be created in ODI based on the unbound Pluggable Mapping operator. The created Reusable Mapping is placed in the STAND_ALONE folder under the project where the mapping is placed. The unbound Pluggable Mapping operator is migrated to a Reusable Mapping component and bound to the newly created Reusable Mapping.

Post_Mapping Operator

Sequence Operator

OWB Sequences are migrated to ODI Sequences as described in "OWB Sequence to ODI Sequence". The OWB Sequence operator is not migrated; however, references to OWB Sequences in expressions are migrated to ODI as part of the migration of the expressions.

Set Operator

The OWB Set operator is migrated to the ODI Set component.

Properties of the Set Operator

Set Operation

Set operation is an operator level property in OWB. It has four choices: UNION, UNIONALL, INTERSECT, and MINUS.

ODI has a similar property, but the property is set on the input connector point. Hence, the operator-level OWB Set Operation property is migrated to each input connector point of the Set ODI component except the first input connector point which is left as empty.

The following table displays the migration from OWB Set Operation to ODI set operation type.

Attribute Groups and Attributes of the Set Operator

The operator attribute groups of the OWB Set operator are migrated to ODI component connector points. No specific properties need to be migrated for attribute groups of the Set operator.

Input attributes of the Set operator are not migrated.

Output attributes are migrated. The Output attribute of the ODI Set component can have multiple expressions. Each expression is associated with an input connector point. During migration, the expressions for the ODI attribute will be constructed according to the input attributes of the OWB Set operator. Take the following mapping as an example:

Union1 is a Set operator in OWB. It has two output attributes, and the two input attributes INGRP1.EMPNO and INGPR2.DEPTNO are mapped to OUTGRP1.DEPTNO.

Because INGRP1.EMPNO is connected from EMP.INOUTGRP.EMPNO and INGRP2.DEPTNO is connected from DEPT.INOUTGRP.DEPTNO, the expressions for the output attribute UNION1.DEPTNO in the ODI Set component are set to refer to EMP.EMPNO and DEPT.DEPTNO.

Splitter Operator

The OWB Splitter operator is migrated to the ODI Splitter component.

Properties of the Splitter Operator

Split Condition

Split Condition is an attribute group-level property in OWB. ODI has a similar property, which is set on the output connector point. The Split Condition property on the output attribute group in OWB is migrated to the split condition expression on the output connector point in ODI.

Attribute Groups and Attributes of the Splitter Operator

Output attribute groups of the Splitter operator in OWB are migrated to output connector points in ODI. The output attribute group with the name REMAINING_ROWS in OWB is migrated to the Remainder output connector point in ODI.

Attributes of the Splitter operator are not migrated.

Subquery Filter Operator

The OWB Subquery Filter operator is migrated to the ODI Subquery Filter component.

Properties of the Subquery Filter Operator

Name and Description

The physical name of the Subquery Filter operator is migrated to the Subquery Filter component name. The description is migrated to the component description.

Subquery Filter Condition

The OWB subquery filter condition is mapped to the ODI subquery filter condition.

The subquery filter condition for the ODI Subquery Filter component is as follows:

Subquery Filter Input Role

The OWB subquery filter input role is migrated to the ODI subquery filter input role.

The subquery filter input role for the ODI Subquery Filter component is as follows:

Map Attribute Groups

The OWB Subquery Filter operator has two attribute groups: input attribute group and inout attribute group. The input attribute group of the OWB Subquery Filter operator is migrated to the ODI SUBQUERY_FILTER_INPUT connector point of the ODI Subquery Filter component. The OWB inout attribute group of the Subquery Filter operator is migrated to the ODI DRIVER_INPUT connector point and the output connector point. The two connector points use the default name instead of the OWB inout attribute group name.

Attributes

Attributes in the input attribute group are not migrated. Attributes in the inout group of the OWB Subquery Filter operator are migrated to output attributes of the ODI Subquery Filter component.

An output attribute of the Subquery Filter component has two expressions. The following example describes how these two expressions are set during migration.

Using the following OWB mapping as an example:

This OWB mapping is migrated to the following ODI mapping:

The expressions for each migrated attribute are as follows:

Expression for DRIVER_INPUT Connector Point

For output attributes of the OWB Subquery Filter operator that are connected from an upstream attribute, the expression of these output attributes is set to the ODI DRIVER_INPUT connector point, and the expression references the upstream projector attribute.

In the previous OWB mapping, the attribute SUBQUERY_FILTER.INOUTGRP1.EMPNO is connected from EMP.EMPNO. After migration to ODI, the expression set on the DRIVER_INPUT connector point is EMP.EMPNO.

Expression for SUBQUERY_FILTER_INPUT Connector Point

For output attributes of the OWB Subquery Filter operator with an IN Matching Attribute property set, the expression of this property is set to the SUBQUERY_FILTER_INPUT connector point.

For example, if the IN Matching Attribute value is DEPTNO, when migrating to ODI, DEPT.DEPTNO is set as the expression for the SUBQUERY_FILTER_INPUT connector point in ODI.

Notes About Match Column When Updating Row

Although the property of MATCH_COLUMN_WHEN_UPDATING_ROW in OWB is migrated to KEY_INDICATOR in ODI, several rules govern how the key indicator for the ODI map attribute is set.

When the property "Match by constraint" of the OWB Table operator is set to ALL_CONSTRAINTS, the value set on the property MATCH_COLUMN_WHEN_UPDATING_ROW is not migrated, and the key indicator is set to true for the ODI attribute whose bound object is referenced by any PK/AK.

When the property "Match by constraint" of the OWB Table operator is set to NO_CONSTRAINT, the key indicator of the ODI attribute is set according to the property MATCH_COLUMN_WHEN_UPDATE_ROW of the OWB attribute. If MATCH_COLUMN_WHEN_UPDATE_ROW is set to YES, the key indicator of the ODI attribute should be set to true.

When the property "Match by Constraint" of the OWB Table operator is set to a specific constraint, an update key is set on the ODI Datastore component. The key indicator of the ODI attributes is set automatically when the update key is set.

Migrating an Unbound Table Operator

Mappings that contain an unbound Table operator are not migrated, unless the migration configuration option MIGRATE_UNBOUND_OPERATOR in the migration utility configuration file is set to true.

If the migration configuration option MIGRATE_UNBOUND_OPERATOR is set to true, a data store is created in ODI based on the unbound Table operator. The unbound OWB Table operator is migrated to the ODI Datastore component and is bound to the newly created ODI data store.

Table Function Operator

The OWB Table Function operator is migrated to the ODI Table Function component. OWB has a bound Table Function operator (the operator is bound to a table function) and an unbound Table Function operator, and these two kinds of operators are migrated to an unbound Table Function component in ODI. The OWB Table Function operator can have one input attribute group and one output attribute group. The attribute groups of the Table Function operator are migrated to ODI map connector points.

Migrating the Table Function Operator

Scenarios for the Table Function operator in OWB mappings are as follows.

Scenario 1: Table Function operator acts as source, no input map attribute group, only return group (output attribute group).

OWB mapping:

Mapping in ODI after migration:

The OWB output attribute group RETURN is migrated to the output connector point RETURN in ODI.

OWB output attributes in the group RETURN are migrated to output attributes in the connector point RETURN in ODI.

Scenario 2: Table Function Operator has one input attribute group and one output attribute group, data type of input attributes is scalar

OWB mapping:

Mapping in ODI after migration:

The operator CONSTANT_1 is not migrated. The expressions on its attributes are migrated to the ODI Table Function component attribute.

The OWB input attribute group INGRP1 of the Table Function operator is migrated to the input connector point INGRP1 in the ODI Table Function component. Attributes in the group INGRP1 are migrated to attributes in the connector point INGRP1. The property PARAMETER_TYPE of the input connector point INGRP1 is set to SCALAR.

The OWB output attribute group RETURN is migrated to the output connector point RETURN in ODI. Attributes in the group RETURN are migrated to attributes in the connector point RETURN. If the property RETURN_TABLE_OF_SCALAR of the output attribute in OWB is set to true, the expression of the corresponding output attribute in ODI is set to TABLE_FUNCTION_NAME.COLUMN_VALUE.

Scenario 3: Table Function operator has one input attribute group and one output attribute group, some data types of input attributes are REF_CURSOR

The following figure shows an OWB mapping for which the data type for attribute C in the operator TF_INREF_INSCA_REFREC is a PL/SQL Ref Cursor type, and the operator REF1 is responsible for constructing the Ref cursor.

If the input attribute group contains one or more REF_CURSOR type attributes in the Table Function operator in OWB, an input connector point is added for each REF_CURSOR type in ODI. If the REF_CURSOR type is constructed by a Constructed operator in OWB, the input attribute group of the Construct operator is used to define the REF_CURSOR input connector point for the Table Function component in ODI.

In this scenario, the OWB mapping in the preceding figure is migrated to the ODI mapping in the following figure:

Source TFO_SRC_T2 is connected to TF_INREF_INSCA_RETREC through the input connector point INGRP1. The property PARAMETER_TYPE of INGRP1 is set to REF_CURSOR. The property PARAMETER_TYPE of INGRP11 is set to SCALAR.

D Special Migration Cases

This appendix provides examples of special migration cases.

The following topics are addressed here:

- Tables with Multiple Primary Keys

- Special Cases for Mappings

Tables with Multiple Primary Keys

OWB tables are migrated to ODI data stores. In OWB, tables can have multiple primary keys. In ODI, data stores can have only one primary key. In the case of multiple primary keys, the first primary key is migrated as the primary key in ODI, and the others are migrated as alternate keys.

When this situation occurs, the following warning message is written to the migration utility log file:

{0}:{1} has multiple primary keys. Only one primary key is allowed in ODI, the redundant primary keys will be migrated as alternate keys.

Special Cases for Mappings

Some OWB mappings have different graph structures after they are migrated to ODI. The migration utility attempts to migrate OWB mappings to ODI as closely as possible, but in some cases the resulting ODI mappings may not correspond to the original OWB mapping structure.

The following special cases for mappings are addressed here:

- Two Operators Connected to Same Downstream Operator

- Multiple Operators Connected From and To Same Operator

- Lookup Operator Has a Constant as Input

- Lookup Operators Have No Driver Table (Mapping Is Invalid)

- Multiple Operators Connected to Same Operator, Some with No Upstream Source

- Multiple Operators Connected to Same Operator, All with Different Upstream Operator

Two Operators Connected to Same Downstream Operator

The following figure shows an OWB mapping for which operators EMP and EXPRESSION are both connected to operator TGT_EMP through the same map attribute group INOUTGRP1. This is not allowed in ODI, because each input connector point in ODI can only be connected once.

The OWB mapping in the preceding figure is migrated to the ODI mapping in the following figure.

Multiple Operators Connected From and To Same Operator

The following figure shows an OWB mapping for which operators FILTER and EXPRESSION are both connected to operator TGT_EMP through the same map attribute group INOUTGRP1. This is not allowed in ODI.

During migration, the FILTER and EXPRESSION operators are chained together to ensure that only one is connected to TGT_EMP. As a result, the ODI mapping may be EMP > FILTER > EXPRESSION > TGT_EMP or EMP > EXPRESSION > FILTER > TGT_EMP.

The OWB mapping in the preceding figure is migrated to the ODI mapping in the following figure.

Lookup Operator Has a Constant as Input

The following figure shows an OWB mapping for which the Lookup operator has no upstream source operator, and is only connected from a constant.

The OWB mapping in the preceding figure is migrated to the ODI mapping in the following figure (DEP is the lookup table of the Lookup operator).

The constant operator CONSTANT in the OWB mapping is not migrated to any map component in ODI. Instead, the expression of the constant attribute is migrated, and that expression is set on the Lookup component.

For example, in OWB, if the expression of the attribute CONSTANT.OUTGRP1.NO is set to 5, and the lookup condition of LOOKUP_DEPT is OUTGRP1.DEPTNO = INGRP1.NO, then after migration the lookup condition of LOOKUP_DEPT in ODI is DEP.DEPTNO = 5.

Lookup Operators Have No Driver Table (Mapping Is Invalid)

The following figure shows an OWB mapping for which several Lookup operators are connected to operator TGT_EMP, but some of the Lookup operators have no upstream operators as driver tables. This mapping is invalid, but will also be migrated. Only one map component can be connected to TGT_EMP in ODI. As a result, Lookup operators without driver tables will lose the connection to operator TGT_EMP.

The OWB mapping in the preceding figure is migrated to the ODI mapping in the following figure.

Note that expressions for the target attributes are migrated, even though these two lookup components are not connected.

Multiple Operators Connected to Same Operator, Some with No Upstream Source

The following figure shows an OWB mapping for which two operators are connected to the same operator TGT_EMP. The EXPRESSION operator has an upstream source operator, while the JOINER operator does not. Only one map component can be connected to TGT_EMP in ODI. As a result, the operator with no upstream source operator will lose the connection to TGT_EMP.

The OWB mapping in the preceding figure is migrated to the ODI mapping in the following figure.

Multiple Operators Connected to Same Operator, All with Different Upstream Operator

The following figure shows an OWB mapping for which two operators are connected to the same operator TGT_EMP. Both operators have an upstream operator. Only one map component can be connected to TGT_EMP in ODI. As a result, one operator will lose the connection to TGT_EMP.

The OWB mapping in the preceding figure is migrated to one of the ODI mappings in the following figures.
