APAR status

• Closed as documentation error.

Error description

• Hundreds of ANTPC2 RC28 RSN189C18A4 events are recorded in
  LOGREC due to a PET table initialization failure ( RC6307 ).
  Every subsequent attempt to access data areas in the PET table
  are going to fail because the mpetp_in_head_ptr is zero,
  until another restart of ANTMAIN is done.

Problem conclusion

• A documentation change will been made.
  
  The following updates will be reflected in a future revision
  of z/OS MVS System Messages, Volume 1(ABA-AOM)(SA38-0668):
  
  In the ADR Messages section under ADR735W, reason code 10,
  the following information will be amended:
  
  If DSS message ADR735W is issued with reason code 10,
  indicating that the system data mover is not available, and
  there is a previous SDM message ANTM6999E with RC=6307, then
  any storage shortages that may exist must be resolved and the
  ANTMAIN address space must be refreshed (Cancel of the ANTMAIN
  address space).
  If the ANTM6999E/RC=6307 continues to be observed, ensure there
  are no existing storage shortages and then refresh ANTMAIN
  again.
  
  
  In the ANT Messages section under message ANTM6999E, the
  following will be added to the end of the System Programmer
  Response section:
  
  System programmer response: If return_code is 6307,
  there might be insufficient ECSA available to allocate the
  table. Either increase the system ECSA, or reduce the size of
  the table. See z/OS DFSMS Advanced Copy Services for
  instructions on modifying PET table size. After all system ECSA
  issues have been resolved, the ANTMAIN address space must be
  refreshed (by executing a CANCEL command to ANTMAIN).  If the
  return_code 6307 continues to be observed and all storage
  issues have been resolved report the problem to the IBM Support
  Center. For other errors, search problem reporting databases
  for a fix for the problem. If no fix exists, report the problem
  to the IBM Support Center.
