Oracle® GoldenGate Application Adapters

Installing Oracle GoldenGate Adapters

Release 12c (12.1.2.1.1)

E61859-01

May 2015

This document provides information on how to install a new instance of the Oracle GoldenGate Adapters.

The document contains the following sections:

- Section 1, "Preparing for Installation"

- Section 2, "Installing Oracle GoldenGate Adapters"

- Section 3, "Documentation Accessibility"

1 Preparing for Installation

Prepare your Java environment by ensuring that you have the correct version of Java installed, and that the environmental variables have been set up and configured correctly.

1.1 Installing Java

The Oracle GoldenGate Adapters are certified for Java 1.7. Before installing and running Oracle GoldenGate for Java, you must install Java (JDK or JRE) version 1.7 or later. Either the Java Runtime Environment (JRE) or the full Java Development Kit (which includes the JRE) may be used.

1.2 Setting up Environmental Variables

To configure your Java environment for Oracle GoldenGate for Java:

- The PATH environmental variable should be configured to find your Java Runtime

- The shared (dynamically linked) Java virtual machine (JVM) library must also be found.

On Windows, these environmental variables should be set as system variables; on Linux/UNIX, they should be set globally or for the user running the Oracle GoldenGate processes. Examples of setting these environmental variables for Windows and UNIX/Linux are listed below.

Note:
There may be two versions of the JVM installed when installing Java; one in JAVA_HOME/.../client, and another in JAVA_HOME/.../server. For improved performance, use the server version, if it is available. On Windows, only the client JVM may be there if only the JRE was installed (and not the JDK).

1.2.1 Java on Windows

After Java is installed, configure the PATH to find the JRE and JVM DLL (jvm.dll):

Example 1 Configuring Path for Java on Windows

set JAVA_HOME=C:\Program Files\Java\jdk1.7.0
set PATH=%JAVA_HOME%\bin;%PATH%
set PATH=%JAVA_HOME%\jre\bin\server;%PATH%

In the example above, the directory %JAVA_HOME%\jre\bin\server should contain the file jvm.dll.

Verify the environment settings by opening a command prompt and checking the java version:

C:\> java -version
java version "1.7.0_30" Java(TM) SE Runtime Environment (build 1.7.0_30-b13)

1.2.2 Java on Linux/UNIX

Configure the environment to find the JRE in the PATH, and the JVM shared library, using the appropriate environmental variable for your system. For example, on Linux (and Solaris, etc.), set LD_LIBRARY_PATH to include the directory containing the JVM shared library as follows (for sh/ksh/bash):

Example 2 Configuring path for Java on Linux

export JAVA_HOME=/opt/jdk1.7
export PATH=$JAVA_HOME/bin:$PATH
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/i386/server:$LD_LIBRARY_PATH

In the example above, the directory $JAVA_HOME/jre/lib/i386/server should contain the file libjvm.so. The actual directory containing the JVM library depends on the OS and if the 32-bit or 64-bit JVM is being used.

Verify the environment settings by opening a command prompt and checking the java version:

$ java -version
java version "1.7.0_30"
Java(TM) SE Runtime Environment (build 1.7.0_30-b02)

2 Installing Oracle GoldenGate Adapters

To install the Oracle GoldenGate Adapters, download a zip file of the build for your operating system and platform; then follow the installation steps.

2.1 Installation Overview

This section provides an overview of the installation contents and the Oracle GoldenGate instances used with the Oracle GoldenGate Adapter

2.1.1 Contents of the Installation Zip File

The Oracle GoldenGate Adapters installation zip file contains:

- Oracle GoldenGate Java Adapter

- Oracle GoldenGate Flat File Adapter.

- A version of Oracle GoldenGate designed to run the adapters. This version is sometimes labeled generic because it is not specific to any database, but it is platform dependent.

2.1.2 Using the Generic Build of Oracle GoldenGate

For JMS capture, the Java Adapter must run in the generic build of Oracle GoldenGate. However, the generic build is not required when using the adapter for delivery of trail data to a target; in this case the Oracle GoldenGate Flat File or Java Adapters can be used with any database version of Oracle GoldenGate.

2.1.3 Considerations for Using a Non-generic Instance of Oracle GoldenGate

There are both advantages and disadvantages to installing the adapters to a non-generic Oracle GoldenGate instance. Also, there are limitations in the releases of Oracle GoldenGate core that are compatible with releases of the adapters.

Advantages

- The non-generic instance allows you to configure Extract to login to the database for metadata. This removes the need to use a source definitions file that must be synchronized your the source database DDL.

- There is no need to manage two separate versions of Oracle GoldenGate when doing database capture and JMS delivery on the same server.

Disadvantages

- If you need to patch Oracle GoldenGate core instance, you must also copy the adapters into the new patched installation of Oracle GoldenGate.

- The Oracle GoldenGate Adapters are only tested and certified with the generic version of Oracle GoldenGate core. New patches of the core can trigger incompatibilities.

Limitations

- The Oracle GoldenGate Adapters can only be installed with an Oracle GoldenGate instance that is the same major release. Therefore, 11.1.x releases of the adapters can only be installed to 11.1.x releases of Oracle GoldenGate; 11.2.x with 11.2.x, and 12.1.2.x with 12.1.2.x.

- The generic build must be used with JMS capture, as this is the only version of Extract that is capable of loading the VAM.

- A DEFGEN utility is not included with the adapters. To generate source definitions, you will need a version of Oracle GoldenGate that is built specifically for your database type.

2.1.4 Installing to a Non-Generic Instance of Oracle GoldenGate

If you decide to install the Java user exit to a non-generic instance of Oracle GoldenGate, unzip to a temporary location first and then copy the adapter files to your Oracle GoldenGate installation location

To do this, follow these steps:

1. Extract the Oracle GoldenGate installation zip file to a temporary directory.

2. Extract the Oracle GoldenGate installation zip file into your Oracle GoldenGate installation directory.

3. Copy or move the files from the temporary directory ggjava subdirectory into the Oracle GoldenGate installation directory.

4. Copy or move the shared libraries from the temporary location into the Oracle GoldenGate installation directory.

5. Optionally you can also copy Gendef and flatfilewriter.so or flatfilewriter.dll. (There is no need to copy the shared library ggjava_vam since it works only with the generic build.)

6. Delete the temporary directory.

2.2 Downloading Oracle GoldenGate Adapters

Oracle GoldenGate Adapters are available for Windows, Linux, and UNIX (32 and 64 bit). To download, first visit the Oracle support site to see if there is a patch available for your operating system and architecture.

Note:
If you are not planning to use the generic build included in the installation, ensure that the major release of the Oracle GoldenGate Adapters build you download matches (or is known to be compatible with) the major release of the Oracle GoldenGate instance that will be used with it.

2.4 Installation Steps

Perform the following steps to install the Oracle GoldenGate Adapters:

1. Create an installation directory that has no spaces in its name. Then extract the zip file into this new installation directory. For example:

Shell> mkdir installation_directory
Shell> cp path/to/installation_zip installation_directory
Shell> cd installation_directory
Shell> unzip installation_zip

If you are on Linux or UNIX also:

Shell> tar -xf installation_tar

This will download the files into several of the subdirectories Section 2.3, "Directory Structure."

2. Stay on the installation directory and bring up GGSCI to create the remaining subdirectories in the installation location.

3. Shell> ggsci
GGSCI> CREATE SUBDIRS

4. Create a Manager parameter file:

GGSCI> EDIT PARAM MGR

5. Specify a port for the Manager to listen on by using the editor to add a line to the Manager parameter file. For example:

PORT 7801

6. If you are on Windows and running Manager as a service, set the system variable PATH to include jvm.dll, then delete the Manager service and re-add it.

7. Go to GGSCI, start the Manager, and check to see that it is running:

GGSCI>START MGR
GGSCI>INFO MGR

Note:
To check for environmental variable problems locating the JVM at runtime:

- Add the parameter GETENV(PATH) for Windows or GETENV(LD_LIBRARY_PATH) for UNIX to the Extract parameter file.

- Start the Extract process

- Check the output for the report using the GGSCI command: SEND EXTRACT group_name REPORT
