Using DFHDBFK - The CDBM GROUP command file

Before you begin

Before you can use the GROUP command, CDBM requires a file in which all your predefined commands can be stored. This file, DFHDBFK, is the CDBM GROUP command file. It is a VSAM KSDS. The DFHDBFK file is not required until you first attempt to use the /GROUP command.

About this task

You can use whatever means you prefer to define this file and to maintain its content.

Procedure

  1. To define the file DFHDBFK and optionally to place some of your group definitions in it, use the sample JCL that is described in Defining the CDBM GROUP command data set .
    The example given there also shows you how to batch load this file if you want to do so. You can load many definitions in this way, or load none.
  2. To use the /GROUP command functions of the CDBM transaction, add the data set name of the group command file to the definition of the DFHDBFK file within the DFHDBCTL group.

What to do next

One method of maintaining the content once the file is defined is provided by CDBM which offers a Maintenance function for the DFHDBFK file.
