Error description

• Locks/Claims Owned by Thread (ZTDTL) INCORROUT
  additional symptom:
  After applying UK75348 (APAR PM10045),
  ABEND0C1 in IRLM DXRRL050 module overlaid by zeroes:

  PROBLEM SUMMARY:
  1.Lock processing was not correct when DB2 member name was not
  equal to DB2 subsystem name.
  2.Some changes were not done to display claim and drain locks
  correctly in Classic and TEP in Omegamon V410 and V420.
  3.Some problems can happen during utility processing in Omegamon
  V410 and V420.
  
  PROBLEM CONCLUSION:
  1.Change logic to handle lock processing correctly for all
  versions when DB2 member name was not equal to DB2 subsystem
  name.
  2.Fixed the code to display resource name for global lock owner
  in a UNICODE=Y DB2 subsystem in TEP in Omegamon V410 and V420.
  3.Correct processing of lock data to display not only database
  name and pageset name but page number too in Omegamon V410 and
  V420.
  4.Change logic to calculate more precisely the number of claims
  for DB2 v8 and above in Omegamon V410 and V420.
  5.Changed code for better protection against abend during
  utility processing in Omegamon V410 and V420.
