| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
The following very specialized set of circumstances may cause a
trap during recovery:
- Concurrent forward / reverse index scans are taking place
- An undo of a split of an index leaf is being performed at the
same time
- Isolation level is uncommitted read (UR)
If the problem occurs, the recovery will fail and it will have
to be restarted. |
| Problem Summary: |
The problem is that in the error code path index manager passes
a NULL pointer where it is not expected to be NULL. As a result,
the trap occurs and the recovery fails. |
