Problem IC66505 | Status: Geschlossen |
RARE CONDITION MAY LEAD TO ROLLFORWARD / CRASH RECOVERY PARALLEL FAILURE | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 | |
Problembeschreibung: | |
During parallel recovery, a rare timing condition may cause some internal data to be cleaned up before the other process tries to read it. This could cause a logical assertion to fail during recovery and the instance to be abend. The internal data being prematurely cleaned up is called the object descriptor. In a customer build the problem will fail in function sqlbfix, probe 5 with the following message in the db2diag.log: "fixCB::pageKey and fixCB::obj do not match" Note again this issue only occurs during recovery. | |
