  ****************************************************************
  ABENDS00C4 occurs in IEFWS21D attempting to
  dynamically deallocate IMSACB of the staging ACBLIB during DEDB
  Alter utility execution.
  
  This problem occurred after APAR PI45422.
  

Problem conclusion

• APAR PI45422 changed the way to invoke the staging ACBLIB
  Services processor to serialize the staging ACBLIB access.  This
  in turn caused the ABENDS0C4 in IEFWS21D at dynamic deallocation
  of IMSACB staging ACBLIB during DEDB Alter utility execution.
  
  Module DBFDASP0 has been modified to restore to call the staging
  ACBLIB Services processor directly for the master IMS.
