Error description

• ABEND0C4-04 in DSNXAAPC+1D66 OFFSET1D66 or 1D96 during package
  authorization cache expansion.  A fallout abend could be
  ABEND04E RC00E70005 in DSNXAAPC at P120.
  Possible abends are also in v8.
  ABEND0C4-04 IN DSNXAAPC + 1D96
  ABND04E RC00E20028 DSNSVSTK+0304
  During package authorization cache expansion, the authority
  control exit was seen to be installed, but it was not installed
  into DB2 at startup processing like it should be.  During
  package authorization cache expansion, the length of the cache
  as used when an authority control exit exists was used to clear
  out the old cache.  However, these two lengths are not the same
  and DB2 ended up overwriting storage that was not part of
  the package authorization cache, and subsequently abended.
  Keywords: SMCOVERLAY.  This error applies to DB2 V8 also.
  

Local fix

• Ensure your Authority Control Exit is up to date and follows the
  documented API.  If your exit has not been updated since you
  applied PK92315, then this exit needs to be updated to avoid
  this abend. See OEM info APAR II14490 for details.

  ****************************************************************
  During package or routine authorization cache refresh, the
  following abends occurred:
  
  V9:
  ABEND0C4-04 in DSNXAAPC+1CBE
  ABEND0C4-04 in DSNXAAPC+1D66
  ABEND0C4-04 in DSNXAAPC+1D96
  A possible fallout abend is
  ABEND04E RC00E70005 in DSNXAAPC at P120.
  ABEND0C4-04 in DSNXAANC+27AC
  V8:
  ABEND0C4-04 IN DSNXAAPC + 1D96
  ABND04E RC00E20028 DSNSVSTK+0304
  
  The access control authorization exit was not installed as
  documented, leading DB2 to build a smaller package and routine
  authorization cache at DB2 startup. During cache refresh, DB2
  detected the access control authorization exit was installed
  and used an incorrect size for cache refresh, leading to the
  abends.
  

Problem conclusion

• DB2 code has been fixed to use the correct length during
  package authorization cache and routine authorization cache
  refresh.
