The Database Manager supports the restoring of the database instance after hardware errors. The last state of the database is restored. A prerequisite for this is that all the data specified 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 backup media used for the restore does not depend on the number of parallel backup 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 backup media that can be imported concurrently using the parameter MAX_BACKUP_DEVS. The use of up to 32 tape devices allows you to reduce restore times considerably.
Prerequisites
Note the operator authorizations required for the particular DBM commands.
The prerequisite for executing all other restore commands is to execute the command to restore the database instance first.
