Using the CHANGE.DBDSGRP command

IMS provides the parameters, ADDRECOV and DELRECOV for the CHANGE.DBDSGRP DBRC command.

Use ADDRECOV to identify one or more full-function databases, HALDB partitions, and DEDB areas to add to a recovery group.

Use DELRECOV to identify one or more full-function databases, HALDB partitions, and DEDB areas to delete from a recovery group.

In the following example, the first CHANGE.DBDSGRP command adds members to the recovery group and the second command deletes members from the recovery group:

//CHANGEG1 JOB
//S01 EXEC PGM=DSPURX00,...
.
.
.
//SYSIN DD   *
   CHANGE.DBDSGRP  GRPNAME(DBDSG1)     -
                   ADDRECOV(DB4,DB5)
   CHANGE.DBDSGRP  GRPNAME(DBDSG1)    -
                   DELRECOV(DB1,DB2)
