Defining Structured Infostorage Records › SYSID Concepts › Using MSYSID

Using MSYSID

Sites using multiple SYSIDs to secure their systems can use the standard
CA ACF2 for VM masking technique and a special parameter (MSYSID) with the CHANGE subcommand to change one VMO record for multiple SYSIDs.

ACF
SET CONTROL(VMO)
CHANGE OPTS MSYSID(cpu*) DATE(mdy)
END

The MSYSID parameter applies the change to the VMO record for all SYSIDs that begin with CPU and end with any alphanumeric character. You can also apply this parameter to the LIST subcommand. To list the OPTION records for all SYSIDs, enter the following commands:

ACF
SET CONTROL(VMO)
LIST MSYSID(-) OPTS
END

To list all MAINT records for all SYSIDs, use the following command:

ACF
SET CONTROL(VMO)
LIST MSYSID(-) LIKE(MAINT-)
END

Because MAINT records are qualified, enter the specific name with the qualifier or use the LIKE parameter with a mask.
