If you did not set up CCM_HOME and PATH for
user informix during installation, set
these environment variables now.
The ccmdb backup command also runs the following commands, which improves the speed of database queries:
ccmdb check (UNIX on Informix®) or ccmdb check (UNIX on Oracle)
ccmdb update_statistics (UNIX on Informix)
This synchronization is accomplished by locking the database, dumping the database data, saving the storage root files, and then unlocking the database. While users need not exit their sessions during a backup, the changes they make to their files during a backup might not be backed up.
Information must reside in the database to be successfully backed up. If data is in a user work area, but not in the database, it is not backed up. The ccmdb backup and ccmdb pack commands archive information from the metadata and file systems of the database. They do not back up work areas. Users with copy-based work areas must reconcile changes before the administrator runs the backup. If changes are not reconciled, changes to work areas must be backed up separately.
Use either the ccmdb backup and ccmdb pack command to ensure that the backup contains all required information. Do not rely on file system backup utilities to back up the Rational Synergy database. Ensure successful recovery by using only Rational Synergy backup commands.
You also can use database server archive and restore procedures, or a database dump, but these procedures can require more manual steps. Use ccmdb backup if it is possible and practical for your site.
