The ccm_home variable represents the path to the Rational Synergy installation. The default installation directory is /user/local/ccm.
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 ccmdb variable represents the path to the Rational Synergy database directory on the server. Individual databases are in this directory.
The databases in the ccmdb directory must be visible to all engine hosts that accesses those databases and must, therefore, be either local or mounted across the network. The databases must also be visible (that is, use the same logical path) on computers running Rational Synergy processes.
