DB2 SERVER RUNNING AS A GETAWAY TO ANOTHER LUW SERVER MAY TRAP IN SQLJSPARSEXASYNCCTL() WHILE RUNNING XA APPLICATION | |
product: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problem description: | |
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: <StackTrace> -------Frame------ ------Function + Offset------ 0x090000000278A0DC sqljsParseXASyncctl 0x0900000002789B28 sqljs_ddm_syncctl 0x0900000000DCB3A4 sqljsParseRdbAccessed 0x0900000000E03D54 sqljsParse 0x0900000000AC33F0 sqljsSqlam 0x0900000000B8CEF8 sqljsDriveRequests 0x0900000000B8CC04 sqljsDrdaAsInnerDriver 0x0900000000B8C98C sqljsDrdaAsDriver 0x0900000000B69850 RunEDU 0x0900000000B695B0 EDUDriver 0x0900000000B642EC sqloEDUEntry </StackTrace> Stack traceback can also contain following functions: sqljsParseDrdaSyncctl sqljs_ddm_syncct sqljsParseRdbAccessed sqljsParseP13sqljsDrdaAsCbP14db2UCinterface sqljsDrdaAsDriver sqeAgent sqzEDU sqlzRunEDU sqloEDUEntry | |

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. | |
