Commands for Restoring 

Use

The Database Manager supports the restore of the database instance after hardware faults. The last state of the database is restored. A prerequisite for this is that all the data in the backup history is available.

To obtain the highest possible throughput of data, full and incremental data backups can be imported from a number of backup media simultaneously. The number of parallel media used for the restore does not depend on the number of parallel media used to make the backup originally. Even a backup made to single medium plus continuation media can be imported in parallel.

You define the maximum number of media that can be imported concurrently using the parameter MAX_BACKUP_DEVS. The use of up to 32 tape devices allows you to reduce backup and restore times considerably.

Prerequisites

Note the DBM operator authorizations for each of the DBM Server commands.

The prerequisite for executing all other restore commands is to first execute the command for restoring a database instance.
