Parent topic: Getting Started with the Installation
The Oracle Universal Installer (OUI) is a graphic installation program that prompts you for the input required to install the Oracle GoldenGate binaries and working files, and set the database environment in which Oracle GoldenGate will operate. To use OUI to install Oracle GoldenGate, the following requirements must be satisfied before running the installer.
OUI is a graphical Java application. The host platform must be Java-enabled. The required Java Runtime Environment (JRE) is automatically installed with OUI.
If this is the first time you are installing an Oracle product with OUI, you are prompted to create the Oracle central inventory, which also creates a subdirectory for Oracle GoldenGate to contain inventory information. This subdirectory typically requires 150 kilobytes of disk space.

Oracle GoldenGate uses shared libraries. When you install Oracle GoldenGate on a Linux or UNIX system, you must use the following steps before you run GGSCI or any other Oracle GoldenGate process.
If you will be running an Oracle GoldenGate program from outside the Oracle GoldenGate installation directory on your system:
(Optional) Add the Oracle GoldenGate installation directory to the PATH
environment variable.
(Required) Add the Oracle GoldenGate installation directory to the shared-libraries environment variable.
For example, given an Oracle GoldenGate installation directory of /users/ogg
, the second command in the following example requires these variables to be set:
Command | Requires Oracle GoldenGate libraries in environment variable? |
---|---|
|
No |
|
Yes |
To Set the Variables in Korn Shell
PATH=installation_directory:$PATH export PATH shared_libraries_variable=absolute_path_of_installation_directory:$shared_libraries_variable export shared_libraries_variable
To Set the Variables in Bourne Shell
export PATH=installation_directory:$PATH export shared_libraries_variable=absolute_path_of_installation_directory:$shared_libraries_variable
To Set the Variables in C Shell
setenv PATH installation_directory:$PATH setenv shared_libraries_variable absolute_path_of_installation_directory:$shared_libraries_variable
Where shared_libraries_variable
is one of the variables shown in Table 2-1:
Table 2-1 UNIX and Linux Library Path Variables Per Platform
Platform | Environment variable |
---|---|

|
|
The following is an example of how to set the path in Bourne shell:
=> export LD_LIBRARY_PATH=/ggs/12.3:$LD_LIBRARY_PATH
Note:
To view the libraries that are required by an Oracle GoldenGate process, use the ldd
goldengate_process
shell command before starting the process. This command shows an error message for any that are missing.
