CNGRPxx (specify console groups)

Use the CNGRPxx parmlib member to define console groups. You can specify Start of change HMCS, End of change MCS, SMCS, and extended MCS consoles as members of these groups.

Start of change HMCS, End of change MCS, and SMCS consoles are defined to your system through the CONSOLxx Parmlib member, which is described in CONSOLxx (console configuration definition). For information about defining extended MCS consoles to your system, see z/OS MVS Planning: Operations.

You can use console groups in the following situations:

To specify the order in which consoles are to receive synchronous messages. You specify this group on the DEFAULT statement in the CONSOLxx parmlib member.
To identify the consoles that must be inactive for the system to place the system console into problem determination state. You specify this group in the AUTOACT keyword on the CONSOLE statement for the system console.
