Problem IC90894
|
Status: Geschlossen |
POSSIBLE HANG IN INDEX CLEANUP LOGIC WHEN MULTIPLE ASYNCHRONOUS CLEANUP OPERATIONS ARE ACTIVE ON THE SAME TABLE |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problembeschreibung: |
If a partitioned table has a global index and multiple
partitioned are detached at once, then the Asynchronous
Background Processing
will start a number of db2taskp edus to perform the Asynchronous
Index Cleanup.
It is possible that these edus will start contending with each
other over a particular area of the index and they get stuck in
an endless loop.
Taken call stacks repeatedly should show a pattern where these
stacks can be seen :
sqloWaitEDUWaitPost
sqlplWaitOnWP
sqlplMakeNewRequestNonSD
sqlplrq
sqlilidx
sqliTryToMerge
sqliCleanupKeysOnLeaf
procLeaf2Del
