PM80394: ABEND04E RC00C90101 DSNOALLO ERQUAL5006 AFTER ALTER TABLE ROTATE PARTITION

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An ALTER batch job was run on member A. eg
  ALTER TABLE ADF.ADF_LOG_LOB ROTATE PARTITION
            FIRST TO LAST
            ENDING AT ('yyyy-mm-dd') RESET;
  Then intermittently an abend occurred with title:
  DSN ABND 04E 00C90101 U=userid
  M=(N) C=910 DMC DSNIISRT M=DSNTFRCV LOC DSNOLLM DSNOALLO 5006
                                                                 .
  The abend occurred because the last used high level space map
  according to the LOB table space header page is x'00000001' .
  However the LSD , Lob Space Descriptor in dump storage showed
  it as x'5EFE11'. It looks like the LSD value was not updated.

  ****************************************************************
  The last used high level space map page is cached by each
  data sharing member during the physical open of the LOB
  table space. This cached value is used to validate the
  correct space map page number during the extend of the
  high level space map page. It is also being reset to the
  the first high level space map page during the ALTER
  ROTATE PARTITION operation. However, this value is only
  reset on the member that operates ALTER ROTATE PARTITION and
  not other data sharing members. As the result, the subsequent
  extend of the high level space map, will trigger
  DSNOALLO: 5006 sanity check on any other data sharing
  member. In this case, it is a false detection.
  

Problem conclusion

• DB2 code is modified to remove this sanity check.
