Error description
Intermittent core dump occurs when disconnecting WTX DB2 Database Adapter connection running under Message Broker. The following stack trace is from the failing thread: #14 0x0000020001427300 in SQLFreeEnv () from /usr/WMB70/lib/libbipodbc.so #15 0x000002001b205260 in FreeSqlEnv () from /usr/WSDTX/libs/libm4db2.so #16 0x000002001b21901c in DBS_CleanupConnection () from /usr/WSDTX/libs/libm4db2.so #17 0x000002001b219466 in DBS_FreeConnection () from /usr/WSDTX/libs/libm4db2.so #18 0x000002001af3c52a in DBDisconnect () from /usr/WSDTX/libs/libdbutil.so #19 0x000002001a3bd294 in CMpiUserConnection::Disconnect() from /usr/WSDTX/libs/libdstxpi.so #20 0x000002001a3cc59c in mpiConnectionDisconnect () from /usr/WSDTX/libs/libdstxpi.so #21 0x000002001aa33f62 in _AdapterDisconnect () from /usr/WSDTX/libs/libmercrmgr.so #22 0x000002001aa35748 in InvokeAdapterMethod () from /usr/WSDTX/libs/libmercrmgr.so #23 0x000002001aa35946 in RMThread () from /usr/WSDTX/libs/libmercrmgr.so
Local fix
WTXCQ - WTX00037419 LV / LV Circumvention: None
Problem summary
Users Affected: WebSphere Transformation Extender Launcher, WESB or Message Broker installation that is employing maps that perform DB2 operations. Problem Description: In Message Broker environments, the DB2 adapter causes a crash whenever disconnecting from the very last DB2 connection. The same problem can be seen in other WTX environments if both DB2 and ODBC adapters are used at the same time. Platforms Affected: Linux, zLinux
Problem conclusion
The 64-bit DB2 adapter on Linux and zLinux properly disconnects from the very last DB2 connection. Prior to this fix, when running WTX and attempting to disconnect from the last DB2 connection, the DB2 Adapter invoked the wrong library function (SQLFreeEnv). Now the DB2 adapter invokes the same function, but within the DB2 driver library versus the Broker's ODBC library or IDBC driver library. Delivered in: 8.2.0.6, 8.3.0.5
