OMVS considerations

OMVS is a started task (STC) that IBM z/OS starts at IPL time if you have properly installed and configured IBM z/OS Unix Systems Services.

The OMVS address space stays in storage after issuing the stop command F OMVS,SHUTDOWN. Therefore, TOM must detect the presence of OMVS in the system differently from all other STM objects.

Important

This section is applicable only if you have applied PTF BQO4239 in TOM 8.3 and you have not changed the OMVS cataloged procedure name in z/OS by using the STARTUP_PROC parameter in the BPXPRMxx configuration member.

To define the OMVS object, specify the following:

  • Product: Started Task Management
  • Restart only: Yes (z/OS starts OMVS instead of TOM, unless it abends)
  • Start MVS Command type F OMVS,RESTART
  • Stop MVS Command type F OMVS,SHUTDOWN
  • Auto Detection: Yes (default)
  • No Active Check Program
  • No start or stop validation events

TOM's STM Extension automatically detects the state of OMVS by using the OMVS kernel-ready flag and the MVS DISPLAY OMVS command internally. This is different from other STM objects, which are normally detected by examining the z/OS ASCB control block.

STM also dynamically adds the following start and stop message-type validation events for the OMVS object as BMC AMI Ops Automation hidden rules to signal TOM when OMVS has completed initialization or termination:

BPXI004I OMVS INITIALIZATION COMPLETE

BPXI056E OMVS SHUTDOWN REQUEST HAS COMPLETED SUCCESSFULLY

Important

If you haven't applied PTF BQO4239, or you have changed the STARTUP_PROC parameter, define the OMVS object by specifying the following:

  • Product: Started Task Management
  • Restart only: Yes (IBM z/OS starts OMVS instead of TOM, unless it abends)
  • Start MVS Command type F OMVS,RESTART
  • Stop MVS Command type F OMVS,SHUTDOWN
  • Start validation message-type event: BPXI004I
  • Stop validation message-type event: BPXI056E
  • Auto Detection: No
  • Active Check Program
    • MVS type command: DISPLAY OMVS
    • Response: ACTIVE
    • Response line: 2
    • Interval: 00:00:00 (Is requested on demand by TOM)
