|
Status: Geschlossen |
SMALL TIMING WINDOW WHERE PARALLEL RECOVERY (ROLLFORWARD OR CRAS H RECOVERY) MAY HANG AFTER ALL LOG RECORDS HAVE BEEN PROCESSED. |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
Customer will see that crash recovery or rollforward is not
making progress after it appears that all log records have been
processed. If you generate call stacks, you may see something
similar to this.
The redo master process is waiting :
