Problem IC88637
|
Status: Closed |
DB2 DATABASE SERVER RUNS OUT OF ENTRIES IN RESYNC LIST |
| product: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problem description: |
In a distributed unit of work (DUOW) environment, transactions
which have been prepared but not yet committed are kept in a
linked resync list. This list is used to recover from
transaction commit or rollback failures due to network,
hardware, or software failures. The resync list is stored in the
resync heap with a fixed size, which is in the shared memory of
the server.
If there are a lot of outstanding DUOW transactions, DB2
database server can run out of entries in Resync List during
user activities or during crash recovery with the following
message in db2diag.log:
2011-09-23-15.08.39.785187-420 E1503306A441 LEVEL: Severe
PID : 758298 TID : 110442 PROC : db2sysc

FUNCTION: DB2 UDB, base sys utilities, sqleAddEntryToResync,

MESSAGE : Out of ResyncEntries!
In case that crash recovery hits this symptom, crash recovery
fails. In other cases, if APAR IC79235 has not been fixed yet,
DB2 database server traps afterward, otherwise user's sql fails. |
