Problem IC74090
|
Status: Closed |
CRASH RECOVERY INCORRECTLY UPDATES ACTIVE LOG FILES CORRUPTING THEM |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
With OVERFLOWLOGPATH set and infinite logging enabled
(LOGSECOND=-1) DB2 fails to successfully finish crash recovery.
If DB2 needs log files that have been archived to perform crash
recovery it will retrieve them to the OVERFLOWLOGPATH. During
crash recovery DB2 will check only the OVERFLOWLOGPATH for log
files missing any in the active log path thus ending the forward
(redo) phase prematurely.
The switch from redo to undo phase will result in the incorrect
update to the active log files.
It is only after the switch that DB2 detects the premature end
of the forward phase aborting recovery. Once the files have been
incorrectly updated further attempts at crash recovery are not
possible. |
