Backing Up the Database

As part of its backup cycle, CA View optionally backs up to tape the current disk archive generation of SYSOUT, along with the master index. The TBACKUP initialization parameter determines whether backup and DR processing are done.

CA View allows you to produce a duplicate of its backup tapes. A subparameter of the STORGRPn parameters (unit2-name) determines whether tape duplexing is done.

CA View can also create a DR tape if the DRTAPE parameter is set to YES or ACTIVE. Be aware of the following conditions:

• This tape is not a mirror image of the primary or duplex tape. The DR tape is written during the current Standard or Interim backup cycle and can be sent to the DR site.
• A new DR backup tape can be created for both the Standard and Interim backup cycles depending on how the DRMOD parameter is set, as follows:
  • NEVER—The backup cycle does not append reports to an existing DR backup tape.
  • ALWAYS—The backup cycle always appends reports to an existing DR backup tape until it becomes full.
  • STD—The backup cycle appends reports to an existing DR backup tape during Interim backup cycles and creates a new DR backup during Standard backup cycles.

If you define tape storage groups with the STORGRPn initialization parameters, we recommend that you make STORGRP1 the largest group, to enhance the performance of the backup cycle.

The master index contains the location and attributes of all archived SYSOUT; therefore, we recommend that you let CA View back up the master index automatically. The master index is always backed up to the tape storage group defined by the initialization parameter STORGRP0.
