Auto Routing monitor types

The Control-M JCL Verify monitor which receives the processing request directly from the user is called the Receiver monitor.

The Receiver monitor routes the request, according to the routing parameters (NODE, SYS, or IE) provided by the user, to the Submission monitor, which processes the JCL, checking what would be the results if the JCL would be submitted on the target system. The Submission monitor resolves the Control-M AutoEdit variables.

If Auto Routing is enabled in the request, the Submission monitor then analyzes the JCL for JES routing commands or JOB card keywords that provide instructions for forwarding the JCL to another JESPLEX or SYSTEM for execution. If the JCL includes routing instructions, the Submission monitor routes the JCL to the correct monitor on the target JESPLEX/SYSTEM.

The final monitor where the JCL is fully processed is called the Execution monitor.

The following log report messages indicates the three different types of monitors:

• Receiver monitor
  • CTJM36I Request received by monitor XXXXXXXX on system XXXXXXXX
• Submission monitor
  • CTJM37I Request submitted by monitor XXXXXXXX on system XXXXXXXX
• Execution monitor
  • CTJM0DI Request executed by monitor XXXXXXXX / XXXXXXXX on System XXXXXXXX

If AUTOROUTE=Y and one of the routing parameters (NODE, SYS, or IOAENV) is specified then remote verification can be performed by two remote CTJMONs as follows:

• In the SUBMIT SYSTEM where the JOB will be submitted.

  If CTM AutoEdit and JCL modification is requested, it will be performed by the CTJMON on the SUBMIT SYSTEM.

  Minimal JCL checks are performed by the CTJMON on the SUBMIT SYSTEM to find out whether it is also the final EXECUTE SYSTEM or not.

  If not, it is validated that the JCL will not fail during submission.

• In the EXECUTE SYSTEM where the JOB will be executed.

  Full JCL verification is performed by the CTJMON on this system.

The NODE, SYSTEM, and IOAENV parameters specified by the user in the JCL Verify request, define the SUBMIT SYSTEM where the given JCL will be submitted. Control-M JCL Verify first sends the given JCL to the CTJMON that is associated with the IOAGATE with the mapped IOAGATE NODE name. This CTJMON forwards the request to the target CTJMON in the same SYSPLEX based on the SYSTEM and IOAENV parameters.

When AUTOROUTE=N, the target CTJMON is the final target that will perform the verification request.
