Operator Commands › Defining Multiple VTAM Cross-Memory Regions › Specifying the Parameters: SYSIN Statements

Specifying the Parameters: SYSIN Statements

You should specify as many of the parameters as possible with SYSIN statements to manage multiple regions easily.

The REGION parameter is positional and must be specified in the PARM= statement of the cross-memory task JCL.

You should specify the following parameters in the PARM= statement:

SUBSYS=
RMOAPPL=
XMS=

You can specify the rest of the parameters with SYSIN DD statements. If you place the SYSIN statements in a PDS member, you can alter the parameters without shutting down the cross-memory region; however, the parameters do not take effect until the next time the region is shut down and restarted.
