PM62272: ABEND04E 00C90101 DSNKUNR2 ERQUAL 5007 DURING -START DATABASE SPACENAM COMMAND TO RECOVER AN OBJECT FROM GRECP

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The aforementioned abend happened because the -START DATABASE
  SPACENAM command does not build the recovery range correctly
  when the starting LRSN of members is older than the group-
  wise starting LRSN.
  
  The starting LRSN of members is older than the group-wise
  starting LRSN, and the page's PGLOGRBA is 0, with the member's
  begin RBA being 0.
                                                      (d157888)
  
  There is no known data integrity issue, storage overlay or
  incorrout associated with this issue. After the abend, GRECP
  remains on and still protects the object.

  ****************************************************************
  ABEND04E RC00C90101 may occur during the GRECP/LPL recovery
  process if the member's beginning recovery LRSN (which comes
  from DB2 checkpoint and is based on the restart point for all
  objects being modified by that member, across all buffer pools)
  is older than the group-wide LRSN (which comes from GBP
  checkpoint) and the member's begin RBA is zero. When these
  conditions exist, there is a chance that the recovery process
  will build the recovery range incorrectly.
  
  There is no known data integrity issue, storage overlay or
  incorrout associated with this issue. After the abend, GRECP
  remains on and still protects the object.
  

Problem conclusion

• The group-wide beginning recovery LRSN will be used as the
  member's beginning recovery LRSN if the member's begin RBA
  is zero.
