Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar utility to back up and restore database server data. This will enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.
ON-Bar backup and restore system
Back up with ON-BarYou can use the ON-Bar utility to back up and verify storage spaces (dbspaces, blobspaces, and sbspaces) and logical-log files.
onbar -b syntax: Backing upUse the onbar -b command to back up storage spaces and logical logs.
Use ISM during a backupUse the ism_watch command to monitor backups and restores sent to the HCL® OneDB® Storage Manager server. During a backup, the ISM server automatically routes storage-space data to volumes in the ISMData volume pool and logical-log files to volumes in the ISMLogs volume pool.
Backing up the ISM catalogThe ism_catalog -create_bootstrap command creates a full backup of the HCL® OneDB® Storage Manager catalog when the catalog is first used. Afterwards, the ism_catalog -create_bootstrap command performs incremental backups.

Backing up the ISM catalog

The ism_catalog -create_bootstrap command creates a full backup of the HCL® OneDB® Storage Manager catalog when the catalog is first used. Afterwards, the ism_catalog -create_bootstrap command performs incremental backups.

Therefore, the media or volume containing the first bootstrap creation is always necessary in order to restore the bootstrap successfully.

To avoid the need for the first media or volume during bootstrap restore, a full bootstrap backup must be performed every time. The level must be specified explicitly by using, the underlying savegrp command that ism_catalog -create_bootstrap calls.

To perform a full backup of the ISM catalog every time, run the $ONEDB_HOME/bin/savegrp -O -l full ISMData command as the user root.

In this command, -O is a capital O (not a zero), and ISMData is the pool name where the bootstrap data is saved.

You can edit the $ONEDB_HOME/bin/onbar shell script to replace the ism_catalog -create_bootstrap command with the savegrp command.

Redirect the output (both stdout and stderr) of the savegrp command to the ON-Bar activity log file (specified by the BAR_ACT_LOG configuration parameter in onconfig file).
