The CDBM GROUP command data set, DFHDBFK, is a VSAM
key-sequenced data set (KSDS). The CDBM transaction uses this data set to
provide a repository for stored groups of DBCTL commands, .
Procedure Create the DFHDBFK data set by running an IDCAMS job, an example
of which is shown in Figure 1 . Figure 1. Sample job to define and initialize the DFHDBFK
data set

where dbfkvol is the volume on which the DFHDBFK data
set is to be created and dbfkunit is the unit type for
that volume.
Use this job to load IMS commands or use the maintenance
function within the CDBM transaction.
