You should back up Repository, State, Runtime and Historical databases before you run any new WebSphere® Business Monitor Database Definition Language (DDL) scripts, whether they deploy a new model obchodních ukazatelů or update an existing one.
Backup ensures a safe rollback point if something fails. If you are not concerned with recent data collection, you can roll the database back to a prior state that does not contain tables for a recently deployed model obchodních ukazatelů.
For more information about database backup and restore, refer to DB2® data recovery section.
