PH25835: THE DSENQSHR=DISALLOW KEYWORD IN THE M0 INTERNAL JOB, PREVENTS THE INTERNAL JOBS OF OTHER OSC DRIVER JOBS FROM BEING SUBMITTED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The DSENQSHR=DISALLOW keyword in the M0 internal job, which is
  used to serialize the ONLINE CHANGE jobs, prevents the internal
  jobs of other OSC driver jobs from being submitted.
  
  When multiple OSC driver jobs are executed simultaneously in an
  IMSplex, the OSC internal job data set is used exclusively by
  one of the OSC driver jobs during its online change process,
  preventing other OSC internal jobs from being submitted by their
  OSC driver jobs.

  When multiple OSC driver jobs are executed simultaneously in an
  IMSplex, the OSC internal job data set is used exclusively by
  one of the OSC driver jobs during its online change process,
  preventing other OSC internal jobs to be submitted by their OSC
  driver jobs.
  

Problem conclusion

• This APAR provides a new ENQDSN keyword and OSC has been
  modified to use the new ENQ data set instead of the internal job
  data set for serializing the ONLINE CHANGE jobs.
  
  By this APAR, multiple ONLINE CHANGE jobs are serialized as same
  as before, but no longer prevent other OSC internal jobs to be
  submitted by their OSC driver jobs.
