Identifying the Target System on a Linkage

Use the SYSID parameter on the LINK command to define the scope (target systems) to which cross-system commands can be issued. You can specify one or more systems by system ID, or you can use one of the following keywords to identify a group of systems:

ALL

Identifies all systems in a MIMplex. This is the default if you omit the SYSID parameter.

EXTERNAL

Identifies all systems except the local system.

LOCAL

Identifies the local system only.

You can use the DEFSYS statement to define system IDs. For more information on the DEFSYS statement, see the CA MIM Resource Sharing for z/VM Programming Guide.

For information about changing the value for the SYSID parameter, see Modifying Linkages. To learn how to remove systems from a linkage, see Deleting Linkages.
