The ccm_home variable represents the path to the Rational Synergy installation. The default installation directory is /user/local/ccm.
The installation includes both Rational Synergy and Informix® executable files. The Informix executable files are in the informix directory, under $CCM_HOME.
You must be able to write to ccm_home as user root. If the file system is on a local disk, you can install the Rational Synergy software without changing your mount options.
The informix_chunkfiles variable represents the path to the Informix chunk files (dbspace) on the server.
The chunk file directory must be on the Informix server and must be a local file system. Your chunk file paths must be fewer than 66 characters. Use raw disks for chunk files (for more information, see Creating Informix chunk files.
You can use NFS file systems for databases and work areas, but not for chunk files. If you use NFS file systems for databases and work areas, NFS attribute caching must be turned off.
