Regions Separated by REGIONIDs and APPLID

Each separate VTAM region attached to a SUBSYS must have a unique REGIONID.

You must specify the REGIONID as the first parameter of the PARM= statement in the start procedure JCL for the cross-memory online retrieval task. A region does not start if another region with the same REGIONID is already running for the same SUBSYS.

Each separate VTAM region attached to a SUBSYS must have a unique VTAM APPLID.

The USSTAB (defined in Step 2 of Installing the VTAM Online Retrieval Option in the Installation Guide) or your session manager passes all VTAM logon requests to the Primary VTAM APPLID. CA View reroutes requests to other regions if the Primary is full or marked as unavailable. Each VTAM APPLID must have AUTH=(ACQ,PASS) and you must specify the cross-memory parameter VTAMPASS=YES for all of the regions.
