  ****************************************************************
  During the DB2 11 ENFM process three catalog table spaces are
  converted and their tables are moved into individual PBG
  table spaces: SYSSTR, SYSCOPY, and SYSRTSTS. The original three
  table spaces are then dropped at the end of their ENFM
  processing steps.
  
  The DSNDB06 object descriptors for these three table spaces are
  marked invalid during the DROP process but they will be kept
  in memory until their use count goes down to zero. An in-process
  utility will still have pointers to these invalidated object
  descriptors (OBD). Since various OBD fields are zeroed out
  during DROP processing it is possible for these in-process
  utilities to come across a zeroed pointer for one of these three
  dropped catalog table spaces. This is what happened in the
  reported case and the COPY utility abended:

Problem conclusion

• Code has been changed so that catalog objects dropped during
  an ENFM process are properly handled. While the reported case
  involved the COPY utility, the code fix ensures that all DB2
  utilities will properly handle these same situations.
