Problem IC74235
|
Status: Geschlossen |
POSSIBLE ABEND CALLING BACKUP AND SNAPSHOT APIS IN MULTITHREADED APPLICATION |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
When a multithreaded application is using different db2 APIs
e.g.db2Backup and db2GetSnapshot
and they do not operate within separate contexts, then the
application may possibly abend with a number of possible stack
traces.
e.g.
csmSetCursorBuf
sqlak_callbDrdaOutput
sqlak_callbDrdaExecuteOutput
sqljrParseExecuteReply
sqljrParse
sqljrDrdaArCall
sqleproc
sqlerInvokeKnownProcedure
The recommendation to this is to use a separate context for each
thread. This is documented under the
"Concurrent transactions and multi-threaded database access in
embedded SQL applications"
topic in the Online DB2 documentation
(
