The Optim Workstation will also report the following upon selecting the Optim Server:

Unable to communicate with server <server name>.
Optim directory <directory name> is unknown
Unexpected response from internal component, RC:-1

Cause

The AIX 11.x 32 bit Oracle client no longer uses the <Oracle_home>/lib32 directory and has moved to just <Oracle_home>/lib directory. The Optim server cannot find the correct Oracle client library files to use the Oracle client, thus reporting that it can't find the Optim directory

Environment

AIX 6.1 and Oracle 11.x

Resolving the problem

For Optim to operate correctly, the following symbolic links are required:

Go to $ORACLE_HOME/lib: 
ln -s libclient11.a libclient10.a

Go to $ORACLE_HOME: 
ln -s lib lib32
