Multiple System SYSID Use

Sites using multiple systems can use a different SYSID name for each system to secure each system. This lets you create a different set of VMO records for each SYSID, or you can share one or more VMO records between systems.

You define the naming conventions for the SYSID. For example, in the ACFFDR of each system, you can specify:

@SYSID CPU1
@SYSID CPU2

To share a VMO record between multiple CPUs, use masking characters in the SYSID field. For example, to share the VMO record between CPU1 and CPU2, set the SYSID to the CPU ID that the OPTS VMO record controls. You can create a new VMO record through one of the VMO records as an example. The new record uses a SYSID that contains masked characters. You can then delete the VMO records for CPU1 and CPU2 with the ACF command.

ACF
SET CONTROL(VMO) SYSID(cpu*)
INSERT OPTS USYSID(cpu1)
DELETE OPTS SYSID(cpu1)
DELETE OPTS SYSID(cpu2)
END
