Specifying alternate systems—DFHCLT TYPE=LISTSTART

This macro defines the start of the set of commands and messages that the alternate CICS® issues when it takes over from the active CICS. (There may be no commands or messages, but you still need a CLT, so that authorization checks can be made.)

FORALT=((applid1,jobname1)[,(applid2,jobname2),...] )
Specifies pairs of alternate and active CICS systems.
applid1
The name of the alternate CICS that issues the set of commands and messages when it takes over. This name must be the specific APPLID, defined in the APPLID system initialization parameter. It is used as an authorization check.
jobname1
The name of the active CICS system from which the alternate system is taking over. This name must be the MVS™ JOBNAME for the active CICS system. It is used as a security check, to ensure that the alternate system does not attempt to cancel any job other than one of that name.

You may extend this, using more pairs of applid and jobname, so that you can use one CLT for several alternate CICS systems.
