* PROBLEM DESCRIPTION: GRECP recovery fails with ABEND04E      *
*                      RC00C90101 in DSNKUNR2.                 *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
A timing window between two members connecting to a group
buffer pool (GBP) causes the first member completing the
connection to take a structure checkpoint with incorrect
recovery LRSN of the second member. If the next structure
checkpoint happens after the second member's DB2 checkpoint,
page sets using the GBP may get incorrect recovery LRSN. If
the GBP is purged or DB2 crashes, the recovery may fail
with abends.

    



Problem conclusion


    

  • DB2 GBP connection logic has been modified to initialize the
member recovery LRSNs correctly.
