Installing Oracle GoldenGate Application Adapters
Release 12c (12.2.0.1)
E76797-01
June 2016
This document provides information on how to install a new instance of the Oracle GoldenGate Application Adapters.
The document contains the following sections:
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.
The Oracle GoldenGate Application Adapters are certified for Oracle Java 1.7. Before installing and running Oracle GoldenGate, you must install Oracle Java release 1.7 or later. Either the Java Runtime Environment (JRE) or the full Java Development Kit (JDK), which includes the JRE, may be used.
To configure your Oracle Java environment for Oracle GoldenGate:
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 or 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 or Linux are as follows:
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).
After Java is installed, configure the PATH to find the JRE and JVM DLL (jvm.dll):
Example 1-1 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)
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 or UNIX, set LD_LIBRARY_PATH to include the directory containing the JVM shared library as follows (for sh/ksh/bash):
Example 1-2 Configuring path for Java on Linux and UNIX
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)
Note:
For AIX platforms, you must set LIBPATH as follows:
LIBPATH=JAVA_HOME/jdk7/jre/lib/ppc64:$LIBPATH
To install the Oracle GoldenGate Application Adapters, download the compressed file of the release for your operating system and platform; then follow the installation steps.
This section provides an overview of the installation contents and the Oracle GoldenGate instances used with the Oracle GoldenGate Application Adapter
The Oracle GoldenGate Application Adapters installation compressed 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 though it is platform dependent.
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. This is the recommended installation though the Oracle GoldenGate Java Adapter works with any source trail of the same or older supported Oracle GoldenGate release. These source trail files can be generated from any source supported database certified with Oracle GoldenGate (Oracle, MySQL, Sybase, Teradata, DB2 for i, and so on). When you use this generic build, Oracle GoldenGate reads from the trail file generated, and then streams operation data to flat files, JMS, and custom adapters.
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 that are compatible with releases of the adapters. When you use a non-generic build (database-specific release of Oracle GoldenGate) that monitors and the changes data in a source database then writes the changed data to a trail file.
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 Application 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 Application 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, 12.1.2.x with 12.1.2.x, and 12.2.0.1.x with 12.2.0.1.I.
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.
If you decide to install the Java user exit to a non-generic instance of Oracle GoldenGate, extract to a temporary location first, and then copy the adapter files to your Oracle GoldenGate installation location
To do this, follow these steps:
Install the non-generic version of Oracle GoldenGate into your Oracle GoldenGate installation directory.
Extract the Oracle GoldenGate Application Adapters compressed file to a temporary directory.
Copy or move the files from the temporary directory ggjava subdirectory into the Oracle GoldenGate installation directory.
Copy or move the shared libraries from the temporary location into the Oracle GoldenGate installation directory.
(Optional) You can also copy gendef and flatfilewriter.so or flatfilewriter.dll. (There is no need to copy the shared library ggjava_vam because it only works with the generic build.)
Delete the temporary directory.
Oracle GoldenGate Application 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 platform.
Note:
If you are not planning to use the generic build included in the installation, ensure that the major release of the Oracle GoldenGate Application Adapters release you download matches (or is known to be compatible with) the major release of the Oracle GoldenGate instance that you will use it with.

If you decide to install the Java user exit to a non-generic instance of Oracle GoldenGate, extract to a temporary location first, and then copy the adapter files to your Oracle GoldenGate installation location
To do this, follow these steps:
Install the non-generic version of Oracle GoldenGate into your Oracle GoldenGate installation directory.
Extract the Oracle GoldenGate Application Adapters compressed file to a temporary directory.
Copy or move the files from the temporary directory ggjava subdirectory into the Oracle GoldenGate installation directory.
Copy or move the shared libraries from the temporary location into the Oracle GoldenGate installation directory.
(Optional) You can also copy gendef and flatfilewriter.so or flatfilewriter.dll. (There is no need to copy the shared library ggjava_vam because it only works with the generic build.)
Delete the temporary directory.
Perform the following steps to install the Oracle GoldenGate Application Adapters:
Create an installation directory that has no spaces in its name. Then extract the compressed file into this new installation directory:
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, use this command also:
Shell> tar -xf installation_tar
This extracts the files into several of the subdirectories Installation Directory Structure.
From the installation directory, start GGSCI.
Create the remaining subdirectories in the installation location:
Shell> ggsci GGSCI> CREATE SUBDIRS
Create a Manager parameter file:
GGSCI> EDIT PARAM MGR
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
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.
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.
