The ccmdb upgrade command converts a database
from a previous release.
Here is a brief description of the ccmdb upgrade command.
For a detailed description and UNIX usage
instructions, see Upgrading Rational Synergy on Windows or Upgrading Rational Synergy on UNIX.
The upgrade program converts
a database from Releases 6.3, 6.4, or 7.0 to Release 7.1. You must
upgrade a database from a previous release before using it with Release
7.2.
The upgrade program performs the following actions on each
database that it upgrades:
- Updates the target database schema to the Release 7.2 schema.
- Updates the target database version to 7.2.
- Saves the previous migrate rules as database_path/lib/Unix/migrate.old.
- Saves the previous pt directory as database_path/oldpt.
- Saves the previous bin directory as database_path/oldbin.
- Saves the previous notify directory as database_path/lib/oldnotify.
- Protects the target database.
- Exports any types that were modified since a previous model installation
to the database_path/old_types directory.
If the upgrade cannot determine the time of the previous model installation,
it exports all standard types. Then, it uses alternative algorithms
to identify any modified types.
- Finds the list of models installed in the target database.
- Installs the required list of models and model additions from
the model database to the target database.
- Unprotects the target database.
- Restores the original migrate rules file saved in step 3, and
performs any upgrade that is required.
- Starts a 7.2 session on the target database.
- Runs the ccm db_update -update command to update
the data in the target database to 7.2 format.
- Removes obsolete files from the target database.
- Assigns the new database to the appropriate server.
