A new environment variable, SYBOCS_CFG, allows you to override the following default external configuration file paths:
UNIX: $SYBASE/$SYBASE_OCS/config/ocs.cfg
Windows: %SYBASE%\%SYBASE_OCS%\ini\ocs.cfg
To configure SYBOCS_CFG, see the Open Client and Open Server 15.0 Configuration Guide for your platform.
