Specifying the repository group
The group identifier is used as a part of the record key for allocation rules and statistics catalog entries contained in the repository catalog. The group identifier is used in the search for the dynamic allocation rules for creating statistics data sets, and for adding the statistics catalog entry to the repository catalog.
The REPOSITORY_GROUP keyword is intended to provide a means to distinguish between two or more database areas having identical names. For example, to distinguish between the test and production versions of a database, set REPOSITORY_GROUP=TEST or REPOSITORY_GROUP=PROD.
When an online analysis is performed, the default value for REPOSITORY_GROUP is the IMS subsystem identifier. When an offline analysis is performed, the default value for REPOSITORY_GROUP is @@@@.
