Problem IC66501
|
Status: Geschlossen |
RARE CONDITION MAY LEAD TO ROLLFORWARD / CRASH RECOVERY PARALLEL FAILURE |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 910 - 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"
There is also a chance that this problem is hit in the following
code path as well:
sqloDumpEDU + 0x14
sqle_panic__Fv + 0x34
sqlb_panic + 0x88
sqlb_panic@glue134 + 0x74
sqlbSetupObjDesc + 0x1AC

sqleSubCoordProcessRequest + 0x1C0

Note again this issue only occurs during recovery. |
