About ARMBGPS

Use the ARMBGPS program to create a set of object sets to be used for backup and recovery.

ARMBGPS automatically divides the objects identified by the object set definition into multiple balanced object sets. These object sets can then be treated as independent units for backup and recovery purposes.

Warning

ARMBGPS is designed to drive the backup process and is not intended to be run at recovery time.

The patterns that you use for object set definition determine the object sets created.

Warning

You must make a full image copy of the full subsystem directly after running ARMBGPS. Only then can you can make full or incremental copies of all or part of the subsystem and make use of the XUNCHANGED option of ARMBGEN. For more information about XUNCHANGED, see ARMBGEN—Backup and recovery JCL. How frequently you run ARMBGPS depends on the volatility of the DB2 system’s objects. If table spaces are created frequently or significantly change size frequently, run ARMBGPS each time before you make full copies of the entire subsystem. Never run ARMBGPS more frequently than the full copy cycle. The object sets created by ARMBGPS must match the grouping of the full copies of the full system.

With each new release of BMC AMI Recovery Manager, you must rebuild your ARMBGPS object sets for subsystem recovery.

If you use INCLUDE patterns for object set definition, ARMBGPS builds object sets for a subset of the Db2 subsystem. These object sets are called ARMBGPS application object sets. Creating ARMBGPS application object sets is a new way to create object sets in BMC AMI Recovery Manager and simplifies the method for generating multiple jobs for an application. (Recovery Object Sets is an entry on the Object Selection panel (ARMUS001) to generate ARMBGPS JCL for these application object sets.)

ARMBGPS returns LOB, XML, and History objects with their related base table space, not by using their explicit name.

You can create ARMBGPS JCL in the following ways:

After you have created your object sets with ARMBGPS, you can then use ARMBGEN to generate one backup job and one recover job per object set. For more information, see ARMBGEN—Backup and recovery JCL. You can also use the online interface to generate backup and recover JCL.
