Step 35A: Specify Required Control Region Parameters

Modify all IMS Control region and IMS DB control region JCL to specify the following parameter:

CMDMCS=Y

This is required for correct operation of IMS product automation.

Note: Depending on your security requirements and authority assignments, CMDMCS can also be set to values of R, C, or B. For more information, refer to the IMS System Definition Reference.

Modify the IMS DBCTL control region JCL to specify the following parameter:

PREMSG=N

This is required for correct operation of IMS Product Automation.

Note: If PREMSG=Y is selected, all system messages and command responses are issued as multi-line messages. The first line is: DFS000I MESSAGE(S) FROM ID=XXXX where XXXX is the IMSID. The message starts on the second line. As a result, IMS message automation will not work as expected.
