Issue/Introduction
For CA Workload Automation CA 7 Edition, use the CA Datacom DBUTLTY BACKUP command to back up the database. If a restore is required, use the CA Datacom DBUTLTY LOAD command. CA Datacom supports many types of backups, with each type suited for a different purpose. For CA 7, the backups are known as Stable Backup and Hot Backup.
Resolution
Stable Backup
Stable Backups are used for sites that are not concerned with recovering data to the point of failure. For example, a CA 7 in your test environment or a planned disaster recovery may require only a weekly backup since you do not require an up to the minute of failure.
For a stable backup use the JCL from CAL2JCL member AL2DBKUP. CA 7 must be down to run this backup as it requires exclusive access to the data.
To restore the stable backup, use CAL2JCL member AL2DLOAD.
Hot Backup
Hot Backups are used for sites that are concerned with recovering data up to the minute of point of failure. It is also for sites that do not want to stop CA 7 just to run a backup of their data.
You can only use hot backup if your CA Datacom MUF has an option of LOGRCV set to NO and the recovery files are being generated using LXX Spilling.
To run the hot backup, use the JCL that is provided in CAL2JCL member AL2DBHOT. We recommend that you run AL2DBHOT nightly, preferably during a low period of CA 7 activity.
To restore from the hot backup, you will need to use the data output from the last AL2DBHOT job and restore using CAL2JCL member AL2DLOAD. Once this is complete, run the JCL that is in CAL2JCL member AL2DBREC using the spill files created since your last hot backup.
** NOTE ** Before you restore the hot backup for your production data, call CA Datacom and CA 7 support and open a severity one issue.
