Problem IC61857

Status: Geschlossen |
DB2 SERVER RUNNING AS A GETAWAY TO ANOTHER LUW SERVER MAY TRAP IN SQLJSPARSEXASYNCCTL() WHILE RUNNING XA APPLICATION |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
DB2 server accessed by an XA application doing many local
transactions may abort with a SEGV signal in
sqljsParseXASyncctl() function. This happens only when LUW
Server is used as a gateway to another LUW server.
The EDU which traps is db2agentg.
The problem is caused if the application had at least 3 internal
rollbacks for local transactions previously. For example
deadlocks (SQL0911) could cause such rollbacks.
A typical stack trace from the trap file may look like this:

| Problem-Zusammenfassung: |
Users Affected: ALL
Problem Description: See Error Description.
Problem Summary: See Error Description. |
| Local-Fix: |
If possible avoid using the DB2 LUW server as a gateway.
For example when accessing the database via a catalogued local
loopback you will be using the gateway. So in this case connect
to the local database directly and not via the loopback. |
