1 Understanding Compatibility and Interoperability

This chapter provides an introduction to compatibility and interoperability and describes how to identify areas where compatibility and interoperability considerations may arise when you are upgrading Oracle Fusion Middleware 11g components, applying patch sets, or installing new Oracle Fusion Middleware components.

- Section 1.1, "What is Compatibility?"

- Section 1.2, "What is Interoperability?"

- Section 1.3, "Understanding Interoperability and Compatibility with Supported Databases"

- Section 1.4, "Identifying Potential Compatibility and Interoperability Issues"

1.1 What is Compatibility?

For the purposes of this guide, compatibility is defined as the ability of two Oracle Fusion Middleware components of different versions (or releases) to interoperate. It is possible that you will have compatibility considerations when upgrading Oracle Fusion Middleware 11g or when applying Oracle Fusion Middleware 11g patch sets.

When upgrading, for example, you may need to know which components must be updated so that your existing integration points continue to work. When applying a patch set you may want to know if the new products will work with other products of the same release or if they will continue to work with previous versions.

Chapter 2, "Compatibility and Interoperability Between 10g and 11g Components" provides information about the compatibility of specific Oracle Application Server 10g products with Oracle Fusion Middleware 11g Release 1 (11.1.1.6.0) products.

Note:

Compatibility applies to the interaction of components that are installed as part of different Oracle Fusion Middleware patch sets, such as the compatibility of 11g Release 1 (11.1.1.3.0) components with 11g Release 1 (11.1.1.6.0) components. Compatibility issues can arise when at least 1 of the first 4 digits in the release number is different (11.1.1.4.0 and 11.1.1.5.0).

Compatibility can be further broken down into the following:

- Compatibility Between Oracle Fusion Middleware Software Suites

- Compatibility Within Oracle Fusion Middleware Software Suites

1.1.1 Compatibility Between Oracle Fusion Middleware Software Suites

When you are upgrading your Oracle Application Server 10g environment to Oracle Fusion Middleware 11g, you will likely update one area of your environment at a time.

For example, you might upgrade the middle tiers in one department to Oracle Fusion Middleware 11g in order to support new Oracle SOA Suite features. At the same time, you might leave your company-wide Oracle Identity Management components at Oracle Application Server 10g.

1.1.2 Compatibility Within Oracle Fusion Middleware Software Suites

While you are upgrading your Oracle Application Server environment to Oracle Fusion Middleware 11g, you should also consider potential compatibility issues within a specific software suite.

In most cases, issues are temporary and occur only during the upgrade process. After you finish the complete procedure for upgrading the software suite, the issues are typically resolved. However, you should still be aware of these potential concerns, because they can influence your upgrade planning.

1.2 What is Interoperability?

For the purposes of this guide, interoperability is defined as the ability of two Oracle Fusion Middleware components of the same version (or release) to work together (interoperate) in a supported Oracle Fusion Middleware configuration. Specifically, interoperability applies when the first 4 digits of the release or version number are the same. For example, Oracle Fusion Middleware 11g (11.1.1.2.0) components are generally interoperable with other 11g (11.1.1.2.0) components.

In some cases there may be interoperability issues between Oracle Fusion Middleware software suites. For example, you may experience issues with the co-existence of domains between Oracle Fusion Middleware 11gR1 products such as SOA and WebCenter.

See Chapter 3, "Interoperability Between Oracle Fusion Middleware 11g Components" for information on the interoperability of Oracle Fusion Middleware 11g (11.1.1.2.0) components with other 11g (11.1.1.2.0) components.

1.3 Understanding Interoperability and Compatibility with Supported Databases

Each release of Oracle Fusion Middleware 11g is certified against specific database versions. Specifically, you can use these certified databases to host the Oracle Fusion Middleware 11g components schemas.

In some cases, you might have to upgrade your database to a supported version before upgrading to a specific Oracle Fusion Middleware 11g release. For more information on upgrading your Oracle Fusion Middleware components, see Oracle Fusion Middleware Upgrade Planning Guide.

For the latest information about the databases supported by each Oracle Fusion Middleware 11g release, refer to Oracle Fusion Middleware Supported System Configurations on the Oracle Technology Network.

From the Supported Configurations page, you can locate the specific Oracle Application Server or Oracle Fusion Middleware release you are using, as well as the target Oracle Fusion Middleware release to which you want to upgrade. For each Oracle Application Server and Oracle Fusion Middleware release, there is a corresponding spreadsheet that lists the certified configurations, including the supported databases.

However, even if a database is certified for use with a particular database version, there may be additional considerations or limitations of that certification. The following section describe a use case scenarios that require additional consideration when using Oracle Fusion Middleware components:

- Section 1.3.1, "Oracle Adaptive Access Manager with Oracle Database"

1.3.1 Oracle Adaptive Access Manager with Oracle Database

Until recently, the Enterprise Edition was the only version of the Oracle database that Oracle Adaptive Access Manager (OAAM) supported. While the Enterprise Edition is still the recommended database version for use with OAAM, some users may now use the Standard Edition if appropriate.

Customers who are considering using Oracle Database Standard Edition with OAAM must be able to answer 'Yes' to each of the following questions:

1. Can your business and IT owners accept production downtime for regular database maintenance? SE has no Online Index Rebuild feature.

2. Does your deployment utilize a single data center? SE does not provide Streams or DataGuard for fail-over.

3. Does your deployment have traffic volumes with less than 200K logins and transactions per day total? SE does not support Partitioning.

If you answered 'Yes' to all three questions above, Oracle will support you using Oracle Database Standard Edition with OAAM.

1.4 Identifying Potential Compatibility and Interoperability Issues

The following sections describe how to identify and answer common compatibility and interoperability issues using information from this guide, Oracle Technology Network (OTN) and other Oracle documents:

- Before You Begin

- Using This Guide

- Using Oracle Certification Matrices

- Understanding the Compatibility Matrices in this Guide

- Collecting Your Component and Infrastructure Information

- Using Release Notes

- Using the Oracle Fusion Middleware Documentation Library

1.4.1 Before You Begin

If you are installing a new product or updating an existing one (either to a new major version or a patch set), interoperability and compatibility issues may arise. During a new product component installation, interoperability considerations relate to the capability of the new product to integrate with other Oracle Fusion Middleware components of the same release.

Compatibility considerations relate to the capability of the new product to integrate with previous versions of Oracle Fusion Middleware products which may have already been installed. During product updates, the question is mainly one of compatibility and you may need to consider the other components that need to be updated so that existing integration points continue to work.

Table 1-1 provides a list of tasks that will help you collect the information necessary to plan your Oracle Fusion Middleware upgrade and installation strategy.

Table 1-1 Tasks for Preparing to Identify and Solve Interoperability Considerations

Task

Description

Documentation

Task 1 - Gather release and version information for your installed components and supporting infrastructure.

In order for you to identify potential interoperability and compatibility issues with your Oracle Fusion Middleware components, you must first collect the release and version information for each component or suite of components you have installed or plan to install or upgrade.

In addition, you should also have version and release information for your operating system, database, JDKs and other third-party products.

See Section 1.4.5, "Collecting Your Component and Infrastructure Information"

Task 2 - If you are planning an upgrade, you should develop an upgrade strategy and understand the supported starting points for upgrading to Oracle Fusion Middleware 11g.

An upgrade starting point is a specific version of Oracle Application Server that you must be running in order to upgrade to Oracle Fusion Middleware 11g. If you are not running a version of Oracle Application Server that is a supported upgrade starting point, then you must first upgrade to a supported starting point using documentation from a previous release.

The Oracle Fusion Middleware Upgrade Planning Guide provides detailed information for developing and implementing an Oracle Fusion Middleware upgrade plan.

In addition, each of the Oracle Fusion Middleware products has an upgrade guide that details the upgrade process and identifies any post-upgrade configuration tasks that must be completed. See Section 1.4.7, "Using the Oracle Fusion Middleware Documentation Library" for more information on locating the correct documentation for your upgrade.

Task 3 - If you are applying a patch set, you should understand the patching requirements for your components and supporting infrastructure.

Patching involves copying a small collection of files over an existing installation. A patch is normally associated with a particular version of an Oracle product and involves updating from one minor version of the product to a newer minor version of the same product (for example, from version 11.1.1.2.0 to version 11.1.1.3.0).

The Oracle Fusion Middleware Patching Guide describes the tools available for you to patch your existing Oracle Fusion Middleware or upgrade your existing Oracle Application Server environment. The guide also describes product-specific prerequisites that must be met before patching.

Information about the latest patches and patch sets is located in the Oracle Fusion Middleware System Requirements and Specifications Document at http://www.oracle.com/technology/software/products/ias/files/fusion_requirements.htm

Task 4 - If you are Installing new Oracle Fusion Middleware components, you should understand the installation requirements and the supported starting points.

Each Fusion Middleware product suite has an installation guide that describes prerequisites, supported starting points and post-installation configuration procedures. It is important to read and follow the installation procedures to avoid potential interoperability and compatibility issues.

1.4.4 Understanding the Compatibility Matrices in this Guide

Interoperability and compatibility matrices are used throughout the book to identify potential issues and to provide links to additional information. When you use the interoperability and compatibility matrices in this guide, the level of support can be defined in one of the following ways:

Table 1-4 How To Use the Matrices in This Guide

Status

Description

Example

Compatible or Interoperable

Integration between the components involved is expected to work with appropriate configuration. It is important to note, however, that compatibility is not a statement of certification. Certification information is located in the certification matrices described in Table 1-3.

For example, the Oracle HTTP Standalone Server 10.1.3 is compatible with Forms, Portal, Reports, Discoverer 10.1.2, but you may have some restrictions depending on your configuration.

Not Compatible or Interoperable

Integration between the components involved is not expected to work.

For example, Oracle HTTP Server 11gR1 is not compatible with Forms, Portal, Reports, Discoverer 10.1.2 and Oracle highly discourages their being used together.

A reference to a specific guide or section

This reference is provided when an individual guide provides more detailed information about the compatibility requirements and considerations that you should review when upgrading, patching or installing Oracle Fusion Middleware 11g.

For example, refer to the Oracle Fusion Middleware Upgrade Guide for Oracle Identity Management for specific information about the interoperability of Oracle Application Server 10g Identity Management components with the Identity Management 11g components.

N/A

Not Applicable.

For example, there is normally no communication or interaction between custom Java EE Applications and Oracle Portal, Forms, Reports, and Discoverer installations.

1.4.5 Collecting Your Component and Infrastructure Information

Oracle Fusion Middleware release and version information is available for each installed component on your system. This information is required before you can effectively identify and solve interoperability or compatibility issues. The certification matrices described in Section 1.4.3 provide certification and system requirements information for Oracle Fusion Middleware components.

This section provides information for the following:

- Locating Oracle Fusion Middleware Product Release Information

- Locating your database-specific version and release information:

- Locating Your Oracle Database Release Information

- Locating your Microsoft SQL Server Version Information

- Locating your DB2 Version Information

- Locating JDK Version Information

1.4.5.1 Locating Oracle Fusion Middleware Product Release Information

To find specific release and version information for your Oracle Fusion Middleware components, see the installed product information using the Oracle Universal Installer (OUI). For more information, see "Viewing Release Numbers" in the Oracle Fusion Middleware Administrator's Guide.

Note:

You can also find version and release information in the installation log files located in the oraInventory/logs directory of your Oracle Home.

1.4.5.2 Locating Your Oracle Database Release Information

To determine the release information of your Oracle database:

Start SQL*Plus from the Oracle home directory:

sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> select * from v$version;

The command returns the release information, such as the following:

Oracle9i Enterprise Edition Release 9.2.0.8.0 - Production
PL/SQL Release 9.2.0.8.0 - Production
CORE 9.2.0.8.0 Production
TNA for 32-bit Windows: Version 9.2.0.8.0 - Production
NLSRTL Version 9.2.0.8.0 - Production

1.4.5.3 Locating your Microsoft SQL Server Version Information

To determine the release information of your Microsoft SQL database:

From the command line, enter the following:

exec xp_msver ProductVersion

The command returns the product version information, such as the following:

ProductVersion 589824 9.00.1399.06

1.4.5.4 Locating your DB2 Version Information

To determine the release information of DB2, do the following:

- From the Windows operating system command line, navigate to the following:

\Program Files\IBM\SQLLIB\BIN>db2level

The command returns the database version and applicable fix pack information such as the following:

DB21085I Instance “DB2? uses “32? bits and DB2 code release “SQL09011? with level identifier “01020107?.
Informational tokens are “DB2 v9.1.100.129?, “s061104?, “WR21374?, and Fix Pack “1?.
Product is installed at “D:\PROGRA~1\IBM\SQLLIB” with DB2 Copy Name “DB2COPY1?.

- From UNIX operating system command line, type the following:

db2ls

This command shows the installation path, version level, fix pack information and installation date of the installed DB2 product. Output from this command goes to the console by default.

Install Path        Level   Fix Pack    Install Number     Install Date
--------------------------------------------------------------------------
/opt/ibm/db2/V9.1   9.1.0.0        0          1    Fri Sep 3 10:26:33 2010 EDT

1.4.5.5 Locating JDK Version Information

Many Fusion Middleware Components are dependent on having a supported JDK installed and configured. The currently supported JDK version information is documented in the Oracle Fusion Middleware Supported System Configurations matrix as described in Section 1.4.3.

To locate your installed JDK version information, navigate to the ORACLE_COMMON_HOME which contains the binary and library files required for Fusion Middleware Control and Java Required Files (JRF). Note that there can be only one Oracle Common home within each Middleware home. Typical Oracle WebLogic Server installations include either an Oracle JRockit SDK or Sun SDK as shown in the examples below:

ORACLE_COMMON_HOME/jrockit_160_17_R28.0.0-679

Or:

ORACLE_COMMON_HOME/jdk160_20

Oracle JRockit JDK 6 R28.0.0 indicates the 28.0.0 release of JRockit JVM used with Java SE 6; similarly, Oracle JRockit JDK 5.0 R28.0.0 indicates the 28.0.0 release of the JRockit JVM used with J2SE 5.0.

The following is an example of a complete release number:

R28.0.0-637-126675-1.6.0_17-20100111-2121-windows-ia32

In this example, R28.0.0 is the JRockit JVM release, 1.6.0_17 is the Java version, and windows-ia32 is the platform on which the release runs.

1.4.6 Using Release Notes

Refer to the Oracle Fusion Middleware Release Notes for specific information about required patch sets that address specific interoperability and compatibility issues which may surface during upgrade or patching process. The release notes for each release are available on the Oracle Technology Network (OTN):

http://docs.oracle.com/

1.4.7 Using the Oracle Fusion Middleware Documentation Library

2.2.3 Oracle Identity Management Suite Interoperability

This section provide answers to specific Oracle Identity Management Interoperability issues:

- Interoperability of Oracle Internet Directory 11g and Single Sign-On 10g

- Oracle Application Server 10g Dependencies on Oracle Identity Management 10g

- Oracle Identity Management 10g Components in a Collocated Home

2.2.3.1 Interoperability of Oracle Internet Directory 11g and Single Sign-On 10g

Oracle Fusion Middleware 11g Release 1 (11.1.1) provides an upgrade path for Oracle Single Sign-On users. Specifically, you can upgrade your Oracle Single Sign-On environment to Oracle Access Manager 11g.

You can also continue to use your existing Oracle Single Sign-On 10g environment with your newer Oracle Fusion Middleware 11g components. However, after upgrading your Oracle Internet Directory (and Oracle Directory Integration Platform) instances to 11g, there are some post-upgrade tasks required in order for Oracle Single Sign-On 10g to work successfully with the upgraded Oracle Internet Directory instance.

For more information, follow the instructions for upgrading Oracle Internet Directory and Oracle Directory Integration Platform in the Oracle Fusion Middleware Upgrade Guide for Oracle Identity Management.

For additional information, see "Evaluating Single Sign-On Installations" in the Oracle Fusion Middleware Installation Guide for Oracle Identity Management

2.2.3.2 Oracle Identity Management 10g Components in a Collocated Home

A collocated Oracle Identity Management 10g Oracle home contains all four of the primary Oracle Identity Management 10g components (Oracle Internet Directory, Oracle Directory Integration Platform, Oracle Single Sign-On, and Oracle Delegated Administration Services). However, you can upgrade only Oracle Internet Directory and Oracle Directory Integration Platform to 11g.

For complete information about the required post-upgrade tasks for Oracle Internet Directory and Oracle Directory Integration Platform, see "Upgrading Your Oracle Internet Directory Environment" in the Oracle Fusion Middleware Upgrade Guide for Oracle Identity Management.

2.2.3.3 Oracle Application Server 10g Dependencies on Oracle Identity Management 10g

Some of the components in Oracle Application Server 10g Release 2 (10.1.2) depend upon specific Oracle Identity Management 10g components. As a result, you should consider the following when you upgrade Oracle Identity Management or Oracle Portal, Forms, Reports, and Discoverer to Oracle Fusion Middleware 11g:

- If you upgrade the Oracle Portal, Forms, Reports, and Discoverer middle tier components to 11g before you upgrade the associated Oracle Identity Management components, then there are no known interoperability restrictions.

- If you upgrade the Oracle Identity Management components to 11g before you upgrade the Oracle Portal, Forms, Reports, and Discoverer components, then the only restriction to consider is when the Oracle Identity Management 10g components are in a collocated Oracle home. See Section 2.2.3.2, "Oracle Identity Management 10g Components in a Collocated Home".

3 Interoperability Between Oracle Fusion Middleware 11g Components

The following sections describe interoperability scenarios to consider when you are using Oracle Fusion Middleware 11g components with other Oracle Fusion Middleware 11g components.

This chapter contains the following sections:

- Section 3.1, "Oracle Web Services Interoperability"

- Section 3.2, "Oracle Identity Management Interoperability"

- Section 3.3, "Middleware Home and Domain Extension Interoperability"

- Section 3.4, "Patch Set Interoperability"

3.1 Oracle Web Services Interoperability

Web services are Web-based applications that use open, XML-based standards and transport protocols to exchange data with clients. Web services are developed using Java Technology APIs and tools provided by an integrated Web services category.

Oracle supports the following Web services categories, which are associated with specific Oracle Fusion Middleware products and components:

- JAX-WS Web Services for Oracle WebLogic Serve

- Web Services for ADF Business Components

- Web Services for Oracle SOA Suite

- Web Services for Oracle Service Bus 11g

These Oracle Web services categories support a variety of Web services message formats, capabilities, and security features. While this support varies from one category to another, all the Oracle Web services categories support the following standard features in the communication messages they send and receive:

- Plain SOAP

- WS-Security, With SSL

- WS-Security, No SSL

As a result, if you develop Web services applications that support these types of Web services messages, then the services you create can be used interoperably with any of the Oracle Web services security categories.

For a more information about the supported WS-Security scenarios between the categories and information on how to configure Web services endpoints, refer to the Oracle Fusion Middleware Interoperability Guide for Oracle Web Services Manager.

For more information about each of the Oracle Web services categories, see the following sections:

- JAX-WS Web Services for Oracle WebLogic Server

- Web Services for ADF Business Components

- Web Services for Oracle SOA Suite

- Web Services for Oracle Service Bus 11g

3.1.1 JAX-WS Web Services for Oracle WebLogic Server

JAX-WS is designed to take the place of JAX-RPC in Web services and Web applications. To compare the features that are supported for JAX-WS and JAX-RPC, see "How Do I Choose Between JAX-WS and JAX-RPC?" in Oracle Fusion Middleware Introducing WebLogic Web Services for Oracle WebLogic Server. For information about migrating a JAX-RPC Web service to JAX-WS, "Migrating JAX-RPC Web Services and Clients to JAX-WS."

3.1.2 Web Services for ADF Business Components

ADF Business Components simplify the development, delivery, and customization of business applications for the Java EE platform by providing a library of reusable components and supporting design time facilities in Oracle JDeveloper.

For more information, see "Integrating Service-Enabled Application Modules" in Oracle Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework.

3.1.3 Web Services for Oracle SOA Suite

Oracle SOA composite applications include the SOA service components. SOA service components are the basic building blocks of SOA applications, implementing a part of the overall business logic functionality.

Note that you can deploy SOA service components to the Oracle Fusion Middleware environment. For more information about developing SOA service components, see Oracle Fusion Middleware Developer's Guide for Oracle SOA Suite.

3.1.4 Web Services for Oracle Service Bus 11g

Oracle Service Bus uses the underlying WebLogic security framework as building blocks for its security services. Specifically, the Oracle Service Bus uses the WebLogic Server JAX-RPC stack to implement its web services and that the WebLogic Server security framework is used for protecting these services.

For information about configuring and attaching policies, see "Using WS-Policy in Oracle Service Bus Proxy and Business Services" in Oracle Fusion Middleware Developer's Guide for Oracle Service Bus.

3.2 Oracle Identity Management Interoperability

This section describes Oracle Identity Management interoperability considerations:

- Interoperability Between Oracle Identity Management and Other Oracle Fusion Middleware Products

- Interoperability Between Oracle Identity Management Components and Oracle Identity and Access Management Components

- Using Oracle HTTP Server 11g WebGates with Oracle Identity Management

3.2.1 Interoperability Between Oracle Identity Management and Other Oracle Fusion Middleware Products

Before you install new Oracle Identity Management components or configure your Oracle Fusion Middleware products to use Oracle Identity Management services, review:

- The Oracle Fusion Middleware certification information to identify which Oracle Identity Management products are compatible with the Oracle Fusion Middleware products you are using. For more information, see Section 1.4.3, "Using Oracle Certification Matrices".

- The information in this chapter, to be sure you are installing and configuring versions of the Oracle Fusion Middleware software that will be compatible with existing and future Oracle Fusion Middleware components.

Similarly, before you apply an Oracle Fusion Middleware patch set, review your current environment and verify that applying the patch set won't affect the interoperability between your Oracle Identity Management components and the Oracle Fusion Middleware products that depend on them. For more information, see Section 3.4, "Patch Set Interoperability".

3.2.2 Interoperability Between Oracle Identity Management Components and Oracle Identity and Access Management Components

Oracle offers two distinct identity management solutions:

- Oracle Identity Management
For more information about the Oracle Identity Management software components available in the current release, see the Oracle Fusion Middleware Installation Guide for Oracle Identity Management

- Oracle Identity and Access Management
For more information about the Oracle Identity and Access Management components available in the current release, see in the Oracle Fusion Middleware Installation Guide for Oracle Identity and Access Management.

These two identity management solutions are often updated independently, as illustrated in Table 3-1, which shows the availability of the Oracle Identity Management and Oracle Identity and Access Management software in recent 11g patch sets.

As a result, you should be aware of any interoperability issues between the available versions or patch sets of the Oracle Identity Management components and Oracle Identity and Access Management components.

In general, unless otherwise noted, you can use different versions of these solutions together, as long as they are not configured within the same domain. For more information, see Section 3.4.4, "Patch Set Interoperability Between Oracle Identity Management and Oracle Identity and Access Management".

Table 3-1 Summary of Oracle Identity Management Patch Set Releases and Oracle Identity and Access Management Patch Set Releases

Oracle Identity Management Availability

Oracle Fusion Middleware 11g Release 1 (11.1.1.6.0)

3.2.3 Using Oracle HTTP Server 11g WebGates with Oracle Identity Management

Oracle HTTP Server WebGates integrate with Oracle Fusion Middleware 11g through the following:

- Weblogic

- Weblogic Identity Assertion Provider that will reside in Weblogic Server

- Oracle HTTP Server 11g Web Tier Utilities

- Oracle HTTP Server 11g Webgates

For more information, see "Introduction to Single Sign-On in Oracle Fusion Middleware" in the Oracle Fusion Middleware Application Security Guide.

- Websphere

- Websphere connector that will reside in Websphere

- IBM HTTP Server 11g Web Tier Utilities

- IBM HTTP Server 11g Webgates

For more information, see Oracle Fusion Middleware Configuration Guide for IBM WebSphere Application Server.

Review the following Oracle Access Management (OAM) integration considerations:

- If you are using a OAM 10g Release 3 (10.1.4.3) backend or server, then use OAM 10g Release 3 (10.1.4.3) versions of OHS 11g WebGates for integration with Oracle Fusion Middleware components.

- If you are using OAM 11g Release 1 (11.1.1), then use OAM 11g Release 1 (11.1.1) versions of OHS 11gR1 webgates.

Note:

For more information about individual Oracle Fusion Middleware product details integrating with OAM, see the product-specific documentation.

For more information about certified versions, see the Oracle Identity Management certification matrix at: http://www.oracle.com/technetwork/middleware/id-mgmt/identity-accessmgmt-11gr1certmatrix-161244.xls.

3.3 Middleware Home and Domain Extension Interoperability

The following sections provide information about the interoperability of Oracle Fusion Middleware products when installing products in a Middleware home and when extending existing Oracle WebLogic Server domains:

- Middleware Home Interoperability

- Domain Extension Interoperability

3.3.1 Middleware Home Interoperability

When installing Oracle Fusion Middleware products, be sure that each Middleware home you create contains only products that are at the same version or patch set. Each product has its own maintenance schedule and it is possible that future interoperability issues could result.

For example, unless otherwise documented, do not install Oracle SOA Suite 11g Release 1 (11.1.1.5.0) in the same Middleware home with Oracle WebCenter Portal 11g Release 1 (11.1.1.6.0).

This rule applies when installing new products, as well as when apply patch sets. For more information, see Section 3.4, "Patch Set Interoperability".

3.3.2 Domain Extension Interoperability

You can extend an existing Oracle Fusion Middleware product domain to support another Oracle Fusion Middleware product, as long as they are the same version number or patch set. For example, if you have an existing SOA Suite 11g Release 1 (11.1.1.4.0) domain, do not attempt to extend or patch that domain using Oracle WebCenter Portal 11g Release 1 (11.1.1.6.0). To avoid potential interoperability issues, wait until both suites are available at equivalent versions.

Table 3-2 describes scenarios when two different products from different Oracle Fusion Middleware suites are collocated within the same domain. In these particular scenarios you will not be able to extend, upgrade, or patch one of the products before the other is available at the same version.

Table 3-2 Domain Extension Interoperability Considerations

Scenario

Description

Solution

Extending a domain with a WebLogic SIP Server

SIP servers cannot be collocated in an existing Fusion Middleware domain.

When extending an existing Fusion Middleware domain deselect the Basic WebLogic SIP Server Domain.

Extending a domain with Oracle Portal, Forms, Reports, and BI Discoverer

Oracle Portal, Forms, Reports, and BI Discoverer should not be collocated with other Oracle Fusion Middleware components

Create a separate domain for Portal, Forms, Reports and Business Intelligence Discoverer.

Extending an Oracle Identity Management domain

Oracle Identity Management does not currently support sharing a domain with any of the other products.

Do not extend an Oracle Identity Management domain with any other Oracle Fusion Middleware components except for those in the SOA Suite.

3.4 Patch Set Interoperability

This section describes some general interoperability guidelines and considerations when you are applying an Oracle Fusion Middleware 11g Release 1 (11.1.1) patch set to an existing Oracle Fusion Middleware environment.

This section contains the following topics:

- Installing Different Patch Sets Within the Same Middleware Home

- Using Different Patch Sets Within a Single Domain

- Patch Set Interoperability Between Oracle Identity Management and Other Oracle Fusion Middleware Products

- Patch Set Interoperability Between Oracle Identity Management and Oracle Identity and Access Management

- Patch Set Interoperability with Oracle WebLogic Server

3.4.1 Installing Different Patch Sets Within the Same Middleware Home

When you are applying an Oracle Fusion Middleware 11g Release 1 (11.1.1) patch set, ensure that all the products within the selected Middleware home are supported by the patch set.

For example, unless otherwise documented, do not install 11g Release 1 (11.1.1.6.0) and 11g Release 1 (11.1.1.5.0) products within the same Middleware home. Each product has its own maintenance schedule and it is possible that future interoperability issues could result.

An exception to this rule is Oracle WebLogic Server 11g (10.3.5), which you can continue to use after you apply the 11g Release 1 (11.1.1.6.0) patch set. For more information, see Section 3.4.5, "Patch Set Interoperability with Oracle WebLogic Server"

3.4.2 Using Different Patch Sets Within a Single Domain

When you configure a domain, ensure that all products configured within the domain are at the same patch set. For example, do not configure Oracle Identity and Access Management 11g Release 1 (11.1.1.5.0) in the same domain with Oracle SOA Suite 11g Release 1 (11.1.1.6.0).

Similarly, if you have configured a domain with Oracle Identity Management 11g Release 1 (11.1.1.5.0) components and Oracle Identity and Access Management 11g Release 1 (11.1.1.5.0) components, do not apply the Oracle Identity Management 11g Release 1 (11.1.1.6.0) patch set until an equivalent patch set for Oracle Identity and Access Management is available.

3.4.3 Patch Set Interoperability Between Oracle Identity Management and Other Oracle Fusion Middleware Products

Oracle often releases Oracle Identity Management products on a schedule different from the schedule for the other Oracle Fusion Middleware products. As a result, it is common to use a different release or patch set of an Oracle Identity Management product with your Oracle Fusion Middleware products, as long as they are not configured within the same domain.

For example, you can use Oracle Identity and Access Management 11g Release 1 (11.1.1.5.0) products with your Oracle SOA Suite 11g Release 1 (11.1.1.6.0) products, if they are in separate domains. In these scenarios, the Oracle Identity Management products are typically installed on a separate host and in a separate Middleware home.

For complete information about the supported Oracle Identity Management patch sets and versions you can use with your other Oracle Fusion Middleware products, refer to the certification information on the Oracle Technology Network (OTN). For more information, see Section 1.4.3, "Using Oracle Certification Matrices".

3.4.4 Patch Set Interoperability Between Oracle Identity Management and Oracle Identity and Access Management

You can configure an Oracle Fusion Middleware environment where Oracle Identity Management and Oracle Identity and Access Management components are at different patch sets, as long as the products are not configured within the same domain.

Do not attempt to configure a single domain that contains Oracle Identity Management components at one patch set and Oracle Identity and Access Management components at another.

For example, as shown in Table 3-3, Oracle does not support the configuration of a domain that contains Oracle Identity Management 11g Release 1 (11.1.1.6.0) components and Oracle Identity and Access Management 11g Release 1 (11.1.1.5.0) components.

Further, if you have an existing domain that contains both Oracle Identity Management components and Oracle Identity and Access Management components, do not apply a patch set unless you can apply the patch set to both the Oracle Identity Management components and Oracle Identity and Access Management components.

For more information about Oracle Identity Management and Oracle Identity and Access Management interoperability, see Section 3.2.2, "Interoperability Between Oracle Identity Management Components and Oracle Identity and Access Management Components".

Table 3-3 Interoperability of Oracle Identity Management and Oracle Identity and Access Management Patch Sets Within the Same Domain

Oracle Identity Management 11g Release 1 (11.1.1.2.0)

Oracle Identity Management 11g Release 1 (11.1.1.3.0)

Oracle Identity Management 11g Release 1 (11.1.1.5.0)

Oracle Identity Management 11g Release 1 (11.1.1.6.0)

Oracle Identity and Access Management 11g Release 1 (11.1.1.3.0)

Oracle Identity and Access Management 11g Release 1 (11.1.1.5.0)

3.4.5 Patch Set Interoperability with Oracle WebLogic Server

Each version and patch set of Oracle Fusion Middleware is certified with a specific release of Oracle WebLogic Server. Create domains for a specific Oracle Fusion Middleware product release only with the certified version of Oracle WebLogic Server.

In the case of Oracle Fusion Middleware 11g Release 1 (11.1.1.6.0), the Oracle Fusion Middleware software is certified to work with both Oracle WebLogic Server 10.3.5 and Oracle WebLogic Server 10.3.6. This allows you to apply the Oracle Fusion Middleware 11g Release 1 (11.1.1.6.0) patch set to an 11g Release 1 (11.1.1.5.0) installation without updating Oracle WebLogic Server.

Note, however, that if you configure Oracle Fusion Middleware 11g Release 1 (11.1.1.6.0) components using Oracle WebLogic Server 10.3.5, you will not be able to take advantage of any of product features that depend upon Oracle WebLogic Server 10.3.6. For information on the new features available in Oracle WebLogic Server 11g (10.3.6), see Oracle Fusion Middleware What's New in Oracle WebLogic Server.

4 Interoperability with Custom and Client Applications

This chapter describes the interoperability considerations of your custom (or client) applications when upgrading Oracle Fusion Middleware components or when applying patch sets. The chapter contains the following sections:

- Section 4.1, "What are custom and client applications?"

- Section 4.2, "Oracle WebLogic Server Interoperability with Custom and Client Applications"

- Section 4.3, "Oracle SOA Suite Interoperability with Custom and Client Applications"

4.1 What are custom and client applications?

When you upgrade from Oracle Application Server 10g to Oracle Fusion Middleware 11g, or if you apply any patches on an existing Oracle Fusion Middleware 11g environment, you should consider the impact on your custom applications as defined as:

- Applications written using JDeveloper

- Applications using any other IDE, but also using any of the Oracle Fusion Middleware public Java APIs.

Specifically, the information in this section applies in the following situations:

- If you have created custom applications that you have deployed on Oracle Application Server 10g or Oracle Fusion Middleware 11g.

- If you have created or if you maintain client applications that interact with applications you deployed on Oracle Application Server 10g or Oracle Fusion Middleware 11g.

Oracle attempts to support binary and source-level compatibility between the current version of Fusion Middleware and patch set updates applied to it. Where incompatibilities arise with public interfaces, they are documented in the related API reference guides at http://download.oracle.com/docs/cd/E14571_01/ref.htm.

Oracle recommends that you ensure the business applications adopting these patch sets and upgrades are tested through your normal release process to ensure there are no regressions.

4.2 Oracle WebLogic Server Interoperability with Custom and Client Applications

In general, applying Oracle WebLogic patch sets should require no additional changes to your custom or client applications. When upgrading, however, you should expect some changes.

For more information on WebLogic Server compatibility, see "WebLogic Server 10.3.1 Compatibility with Previous Releases" in Oracle Fusion Middleware Upgrade Guide for Oracle WebLogic Server.

4.3 Oracle SOA Suite Interoperability with Custom and Client Applications

This section provides information about the interoperability between your upgraded Oracle SOA Suite 10g applications and the client applications that depend upon them.

When you upgrade your Oracle SOA Suite applications to 11g, you must review your client applications and make modifications to the clients before they can interoperate with the upgraded Oracle SOA Suite applications.

In some cases, a patch is necessary before the clients can work with Oracle SOA Suite 11g. For more information, see "Upgrading Oracle SOA Suite Client Applications" in the Oracle Fusion Middleware Upgrade Guide for Oracle SOA Suite, WebCenter Portal, and ADF.
