In environments where there are more than a single VM system or more than a single z/OS system sharing the same database, you can use the examples below as a guide in setting up your DSC parameters.
In both VM systems, the ACF2DSC PARMS file should specify the z/OS system. Choose one VM system as the primary system. In the z/OS system NODEDEF record, set up the primary VM system as a normal node, and set up the other VM system as a receive only node. This lets both VM systems send a synchronization request to the z/OS system, but the z/OS system only sends its synchronization requests to the primary VM. Since the two VM systems are sharing the database, the second VM system does not need synchronization requests from z/OS.
In both z/OS systems, the NODEDEF records should specify the VM system. Choose one z/OS system as the primary system. In the ACF2DSC PARMS file on the VM system, set up the primary z/OS system as a normal node. Set up the other z/OS system as a receiving only node. This lets both z/OS systems send a synchronization request to the VM system. The VM system only sends its synchronization requests to the primary z/OS. Because the two z/OS systems are sharing the database, the second z/OS does not need synchronization requests from VM.
