  ****************************************************************
  After applying V8 PTF UK21411 or for all DB2 9 Utility users the
  following problem can occur:
  A LOAD RESUME YES utility was run on an empty COMPRESS YES
  table space where the INDDN specified on the LOAD statement
  (INDDN SYSREC00) did not match the actual JCL DD card
  (//SYSREC).  The LOAD issued MSGDSNU047I - A REQUIRED DD CARD
  OR TEMPLATE IS MISSING.  NAME=SYSREC00 and MSGDSNU560I -
  TABLESPACE tsname PARTITION 1 IS IN RECOVER PENDING STATE and
  ended with RC8.  The table space should not be left in a RECP
  state when failing early in reload initialization.
  
  The problem can also occur for LOAD RESUME YES on an empty
  COMPRESS YES partition on a partitioned table space and for
  LOAD RESUME NO on an empty COMPRESS YES table space.
  
  After applying V7 PTF UK21410, V8 PTF UK21411, or for all DB2 9
  users the following problem can occur:
  LOAD RESUME YES SHRLEVEL CHANGE on a partitioned table space
  with both empty and non-empty partitions may encounter a
  performance degradation in the UTILINIT phase.  The performance
  degradation was caused by the check which determined if the
  partitions were empty causing additional GETPAGEs compared to
  before.  This check should have only been done for LOAD RESUME
  YES SHRLEVEL NONE on COMPRESS YES partitions.
  

Problem conclusion

• Code has been modified for a LOAD RESUME YES or NO on an empty
  table space to remove the RECP state immediately following the
  procedure that required it.  This will leave the object
  available if an initialization error occurs.
  
  Code has been modified for LOAD RESUME YES to only check for
  empty partitions if SHRLEVEL NONE and COMPRESS YES is
  defined on the partition.
