After installing Oracle GoldenGate for Db2 z/OS on the required operating system, you need to set the following environment variables, before running OGGCA for creating a deployment:

IBMCLIDRIVER: This needs to point to the Db2 clidriver directory.

LD_LIBRARY_PATH: This needs to point to the lib subdirectory under the clidriver directory.

If you do not set these environment variables for Db2 z/OS, the Oracle GoldenGate deployment creation will fail.
