Error description

  • Sometimes during a period of very high IWSz workload, an
    occurrence inserted via ETT is not released by the tracker.
    The operation has these flags set:
    
    Submit=No and Release=Yes
    
    The Operation is Ready and gets a Job Number but no  $AJ
    command is issued by the tracker to release the job.
    When this problem occurs, releasing the job ($AJxxxxx) manually
    corrects the problem.
    
    PI83411 was applied but the problem still occurred.
    .
    This is how the problem can be recreated:
    .
    when the job JTWS#ETT is submitted, the A1 event
    is sent to the controller that adds the occurrence of
    J922870#TWS#ETT to the CP; but in this specific case
    (virtual WS used) the destination of the A1 was not stored.
    This caused the missing release command.
    One scenario to reproduce the problem is the following:
    1. add an occurrence of J922870#TWS#T011 to the CP and make
       sure that the 255 operation is in W status
    2. submit externally the JTWS#ETT job on a destination of the
       virtual WS of the operation 1 of J922870#TWS#ETT
    3. make sure that the operation 255 of J922870#TWS#T011
       becomes completed
    4. at this point you can see that the operation 1
       will be in * status and it is not released

Problem conclusion

  • The problem occurs when the A1 event is received and the
    operation is in Waiting status and run on a virtual work
    station. In this case some internal fields were
    incorrectly set.
