mf.mvs.casspool Properties

This component provides JCL workload management, such as job submission, dispatch, printing and held SYSOUT.

The following table lists the properties of the mf.mvs.casspool component and shows the event information that can be included in the trace for each property.

Property Property Description Level Event Id Event Description
ACTIVE Movement of a job into active status. The job is given to the batch initiator for execution and upon completion of the job the batch initiator signals that it is ready for more work. DEBUG 4 Compiled JCL has been executed.
COMP Submission of JCL by Enterprise Server to be syntax checked. DEBUG 2 A JCL file has been submitted for syntax scanning.
DELETE Removal of a job from the input, output, held, printing or active queues. DEBUG 7 A job has been removed from one of these quese. This could have occurred for the following reasons:
  • an active job has been killed
  • output has been requeued
  • a purge has taken place
DISP Movement of a job from the input queue so that it can be executed by a batch initiator. DEBUG 3 The next available compiled JCL for a given class and priority has been requested for scheduling in an available batch initiator.
OPEN Opening and closing of the casspool.dat file. DEBUG 10 casspool.dat is accessed when starting and stopping an initiator, initializing and terminating an enterprise server, and restarting a generic SEP.
OUTPUT Movement of a job that has completed from the active queue to the output queue and performing of any associated cleanup tasks. DEBUG 5 Compiled JCL has finished executing.
PRINT Routing of a job to a batch printer or a batch printer exit. DEBUG 9 This routing occurs upon job completion for active batch printers or when a SYSOUT is driven to the printer by requeuing.
REPL Replacement of a job that has either been made active or had been requested for execution into either the input or output queues. DEBUG 6 A job bas been replaced. This could have happened for the following reasons:
  • the job was previously active and canceled
  • a protection violation occurred in the batch initiator
  • a protection violation occurred in one of your programs
  • job was canceled by the operator

If the job was previously active it is moved to the output queue for review. If it was never made active then it is replaced in the input queue.

RETRIEVE Requests to retrieve information about a job or SYSOUT DDs that are associated with a job. DEBUG 8 These requests typically occur because of an interaction with ESMAC or when the casout utility needs to retrieve SYSOUT information.
