Operator Commands › Defining Multiple VTAM Cross-Memory Regions › Regions Separated by REGIONIDs and APPLID

Regions Separated by REGIONIDs and APPLID

Be aware of the following:

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 should pass all VTAM logon requests to the Primary VTAM APPLID.

Notes:

• 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.
