Data group record (DBGRP, DBDSGRP, RECOVGRP)

You can use a DBDSGRP record to define the following types of named groups: DBDSGRP, DBGRP, and RECOVGRP.

The named groups are:
  • DBDSGRP, a group of DBDSs and DEDB areas
  • DBGRP, a group of DL/I DBs and DEDB areas that can be named in the DATAGROUP parameter for the /STA, /STO, and /DBR commands
  • RECOVGRP, a group of DL/I DBs and DEDB areas that are logically related for database recovery purposes

All groups must have unique names. For example, a DBDSGRP cannot have the same name as a DBGRP.

You use the INIT.DBDSGRP, CHANGE.DBDSGRP, DELETE.DBDSGRP, and LIST.DBDSGRP commands to manipulate all three data group types.

Recommendation: Although any type of group can be named in the DATAGROUP parameter for the /STA, /STO, and/DBR commands, the use of a DBDSGRP is not recommended because it is inefficient.
