Domino DB2 enabled Notes database restore, rollforward, and activation
Concepts that are associated with Domino DB2 enabled Notes database restore, rollforward, and activation are provided.
Restore
Using Data Protection for HCL Domino you can restore a single DB2 enabled Notes database or a group of DB2 enabled Notes databases. A Domino 8 DB2 Group can be restored from either a full DB2 database backup image or a DB2 table space backup image. Only one DB2 Group can be restored at a time if the DB2 Group is being restored from a DB2 Group backup. The DB2 Group is restored to an alternative DB2 database within the same DB2 instance. If more than one DB2 Group is restored, each DB2 Group must be restored to a different DB2 database. Otherwise, restoring more than one DB2 Group to the same alternate DB2 database overwrites the previously restored DB2 Group. If the DB2 Group is being restored from a full DB2 backup image, then more than one DB2 Group can be restored to the same alternate DB2 database.
A Domino 8 DB2 database can be restored from a full DB2 database backup image to an alternate DB2 database. Using the alternative database, frees the individual DB2 enabled Notes databases for restore. The DB2 database can also be restored directly to the Domino DB2 database. This type of restore operation is useful for disaster recovery purposes.
Rollforward
Rollforward is an intermediate step that is required when the Domino DB2 database is enabled for rollforward recovery. This task rolls the Domino DB2 database forward to the specified point in time and marks the rollforward as complete. The DB2 database can be an alternate DB2 database or the Domino DB2 database.
The Domdsmc query DB2rollforward command displays a list of DB2 databases available to rollforward.
Activation
Activation is the last step of the three stage recovery process. This function brings DB2 enabled Notes databases online for use by the Domino server. DB2 enabled Notes databases that are restored from a DB2 table space backup image can be activated after first rolling the alternate DB2 database forward to the wanted point-in-time. The DB2 enabled Notes database can be restored to a time later than the backup time by applying necessary transaction log files by specifying the /applylogs parameter during the rollforward operation. The logs are then applied to the alternate DB2 database or to the Domino DB2 database if it is an existing restore. The DB2 application automatically archives transaction log files when they become full. The active transaction log files must be archived before you start the rollforward operation to ensure that the latest transactions are available. The necessary logs that are archived are automatically restored during the rollforward operation. The DB2 enabled Notes databases are then copied into the Domino 8 DB2 database to their original filename location or to a new filename location.
DB2 enabled Notes databases that are restored from a full DB2 database backup image are activated in the same manner as described for activating DB2 enabled Notes databases that are restored from a DB2 table space backup image. However, DB2 enabled Notes databases on different table spaces can be rolled forward simultaneously if more than one table space is restored from the full backup image.
The Domdsmc query DB2pendingdbs command displays a list of restored DB2 enabled Notes databases that are available for activation.
