ON-Bar catalog tables

ON-Bar uses the catalog tables in the sysutils database to track backup and restore operations. The onsmsync utility uses other catalog tables to track its operations.

ON-Bar uses the following catalog tables in the sysutils database to track backup and restore operations:
  • The bar_server table tracks instances of the database server.
  • The bar_object table tracks backup objects. A backup object is a backup of a dbspace, blobspace, sbspace, or logical-log file.
  • The bar_action table tracks all backup and restore attempts against each backup object, except some log salvage and cold restore events.
  • The bar_instance table describes each object that is backed up during a successful backup attempt.
The onsmsync utility uses and maintains the following tables to track its operations:
  • The bar_ixbar table contains the history of all unexpired successful backups in all timelines.
  • The bar_syncdeltab table is normally empty except when onsmsync is running.

For a description of the content of these tables, see ON-Bar catalog tables.
