Closed as program error.
Error description
When connecting in managed mode, the application attempts to connect to the first connection defined in the CCDT. If that connection is not reachable, the following exception is seen in MQ trace: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it 1.2.3.4:1414 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.Connect(EndPoint remoteEP) at IBM.WMQ.MQTCPConnection.ConnectUsingLocalAddr(ParsedLocalAddr localAddr, IPAddress ipad, Int32 port) However, no attempt is made to connect to the other connection name defined in the CCDT. The following is also reported in the trace: AMQ9202: Remote host '1.2.3.4(1414),5.6.7.8(1415),9.10.11.12(1416), 13.14.15.16(1417)' not available, retry later.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: MQ .NET managed connection client users who try to connect queue managers with multiple connection names specified in the CONNAME attribute of the client connection channel Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: When multiple connection names were passed in the CONNAME parameter of the channel, the MQ .NET client was attempting to connect to the first connection name. If the first connection name was not reachable, a logic error meant that it did not subsequently attempt to connect using any other connection name specified in the CONNAME parameter.
Problem conclusion
The MQ .NET managed connection client code has been modified to attempt a connection to each entry in the CONNAME, in the order specified, until either a successful connection is established, or the end of the list is reached. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.0 CD 9.0.3 v9.0 LTS 9.0.0.2 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 ---------------------------------------------------------------
