Hi all! We are trying to upgrade Websphere MQ to version 7.1. In our current configuration, MQ Server version is 6.0.2.7 and MQ Client version is 7.0.1.2, with Message Service Client for .NET version 2.0.0.7. We have tried upgrading MQ Client to version 7.1, with Message Service Client version 2.0.0.8. In the client .NET application, we use managed non XA client for transport property. This works fine on the old version, but on 7.1 I get an MQRC_UNEXPECTED_ERROR on initializing the queue manager. If i use unmanaged non XA client, I do not get this error. I have tried following the network traffic and I have found that in version 7.0.1.2 after sending the initial data (queue manager name, channel), User Data and Status Data, the following comands are issued: MQCONN, MQOPEN, MQINQ and MQCLOSE. In version 7.1 everything stops after sending Status Data and the connection is not initialized. I get a MQRC_UNEXPECTED_ERROR, reason code 2195. Here is the code:
ConnectionOptions = new Hashtable();
ConnectionOptions.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_MANAGED);
ConnectionOptions.Add(MQC.HOST_NAME_PROPERTY, HostName);
ConnectionOptions.Add(MQC.CHANNEL_PROPERTY, Channel);
ConnectionOptions.Add(MQC.PORT_PROPERTY, Port);

//here is where I get the error:
QueueManager = new MQQueueManager(QueueManagerName, ConnectionOptions);

Did anyone run into this problem? Any help is welcome!
Thanks,
Florina

What does the associated FDC say? Specifically the ProbeId?

When running the application from our test environment (without any modification for the new version), the FDC created contained Probe Id CO052000. When I debug the application localy, with the dlls from version 7.1, no FDC is created on the server.

Are you sure you have the right version of the dll in the gac?

This is locally. On the test server we had to roll back to v 7.0.1.2 and I didn't have time to check this.

I have tried and it works fine for me. I am able to connect to a remote MQ v6 queue manager from a system that has MQv7.1 installed. I have the complete installation of v7.1 both server and client. But I don't think that makes any difference.

BTW: There is no need to install Message Service Client (XMS) separately as MQ v71 installs XMS. Also XMS 2.0.0.8 is shipped with MQ v701 client and that may not work with MQ v71 client.

Here is my test program:

Code:

public void RunUserIdTest()
{
MQQueueManager qmgr = null;
Hashtable props = new Hashtable();

props.Add(MQC.HOST_NAME_PROPERTY, "remotehost");
props.Add(MQC.PORT_PROPERTY, 2000);
props.Add(MQC.CHANNEL_PROPERTY, "SYSTEM.DEF.SVRCONN");
props.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_MANAGED);

try
{
qmgr = new MQQueueManager("MQQM", props);
int openOptions = MQC.MQOO_FAIL_IF_QUIESCING | MQC.MQOO_OUTPUT;
MQQueue q = qmgr.AccessQueue("SYSTEM.DEFAULT.LOCAL.QUEUE", openOptions);
}
catch (MQException ex)
{
Console.Write(ex);
}
catch (Exception ex)
{
Console.Write(ex);
}
}

Here is my test program:

I removed Message Service Client and reinstalled Websphere client with all features. I tried using your code from a console application and I still get MQRC_UNEXPECTED_ERROR when creating the MQQueueManager. I enabled a trace on websphere and this is what I've got (this happens after sending UserID info):

I have also tried connecting to a v7.1 queue manager and I get the same error with a similar trace.
Do I need to configure anything else in the client application or on the machine running it?

I have also tried the sample program SimpleAsyncPut from tools/dotnet/samples and I get the same error and the same trace. Is there any configuration option that would cause the sever not to receive managed connections from a v7.1 client?

Is your userid longer than 12 characters/ bytes?

I think this is APAR IC82112 (in open state so not externally visible yet)... try contacting IBM support showing the trace info you have and this reference.

We seem to have found the issue. For all channels to which the clients connect (SRVCONN) we have a security exit set to BlockIP. We are able to connect to the channel with v7.1 client without security exit and object authorization. We are still trying to solve this problem without removing the security exit.
Thank you very much for your help!

Most if not all of the features provided by BlockIP are fully supported and available in MQ 7.1.

You may not need the security exit to retain your secured configuration.

I think BlockIP2 has rather more features. I would prefer to use standard features, but seems unlikely for a while.

We also have previously had a long debate about the merits of using DNS names rather than IP numbers.
