Error description
If a .NET application is talking to a server which does not support SPI query calls, the application fails with a 2298 (FUNCTION_NOT_SUPPORTED) when it attempts to query the SPI levels. This results in the MQCONNX call failing. The following exception is seen in a WebSphere MQ trace: -----}! SPINewHObj (rc=MQRC_FUNCTION_NOT_SUPPORTED) ----} UnmanagedNmqiMQ.SPIQuerySPI(Hconn,int,ref int, ref int,ref int,ref int,out int,out int) (rc=OK) ---} UnmanagedNmqiMQ.MQCONNX(String,ref MQCNO,Hconn, Phconn,out int,out int) (rc=OK) --} UnmanagedNmqiMQ.MQCONNX(String,MQConnectOptions, Phconn,out int,out int) (rc=OK) MQException CompCode: 2 Reason: 2298
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All users of .NET talking to WebSphere MQ systems which do not support the SPI verbs, such as WebSphere MQ for VSE. Platforms affected: Windows **************************************************************** PROBLEM SUMMARY: The .NET unmanaged layer assumed that it could query the supported SPI interfaces, and failed to take into account there are systems, such as on VSE, which do not even implement the query function. When used against such a system, an unexpected MQRC_FUNCTION_NOT_SUPPORTED was being returned but not handled.
Problem conclusion
The .NET unmanaged interface has been modified to correctly handle a MQRC_FUNCTION_NOT_SUPPORTED when querying the supported SPI versions, and handle that return code correctly as though no SPI verbs are supported. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.2 -------- -------------------- Windows U200316 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available, information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
