I'm trying to use XMS.Net to connect using a CCDT, but all I get is an error with reason 2277.
Error log says:
AMQ9498: The MQCD structure supplied was not valid.
EXPLANATION:
The value of the 'ChannelName' field has the value '0'. This value is invalid
I'm getting the ConnectionFactory from a .bindings file, and all works fine when the ChannelName is set explicitly and I use Managed mode. However, when I switch to use a CCDT and UnManaged mode (for SSL) I get the error.
My digging in the last few days turned up APAR IZ76986
which says XMS doesn't support WMQ_CCDTURL and to use environment variables intstead. However, this doesn't work either, and neither does using the Channels stanza of mqclient.ini.
I've run some traces to comare my app with amqsputc, which does work.
This is my code
| Code: |
private void button1_Click(object sender, EventArgs e)
{
this.txtLog.Text = "Starting..." + Environment.NewLine;
try
{
IConnectionFactory connectionFactory = CreateConnectionFactory();
Log("Found connection factory...");
Log(connectionFactory.ToString());
Log("End of connection factory settings");
Log(XMSC.WMQ_CCDTURL + ": " + connectionFactory.GetStringProperty(XMSC.WMQ_CCDTURL)); // To prove it is blank
using (IConnection connection = connectionFactory.CreateConnection(null, null))
{
using (ISession session = connection.CreateSession(false, AcknowledgeMode.AutoAcknowledge))
{
using (IDestination destination = (IDestination)this.initialContext.Lookup(this.txtDestinationName.Text))
{
using (IMessageProducer producer = session.CreateProducer(destination))
{
// Start the connection
connection.Start();
IMessage msg = session.CreateTextMessage(this.txtMessage.Text);
producer.Send(msg);
Log("Message Sent");
}
}
}
}
}
catch (Exception ex)
{
Log(ex.ToString());
}
}
private IConnectionFactory CreateConnectionFactory()
{
IConnectionFactory cf;
// Create an initial context instance
Hashtable env = new Hashtable();
env[XMSC.IC_URL] = this.txtICUrl.Text;
this.initialContext = new InitialContext(env);
cf = (IConnectionFactory)this.initialContext.Lookup(this.txtConnFactoryName.Text);
if (cf == null)
throw new Exception(String.Format("Failed to find Connection Factory called {0} in initial context at {1}", this.txtConnFactoryName.Text, this.txtICUrl.Text));
// Set properties not provided by InitialContext
cf.SetIntProperty(XMSC.WMQ_CONNECTION_MODE, (int)XMSC.WMQ_CM_CLIENT_UNMANAGED);
return (cf);
}

This is the trace from it

Note that XMSC_WMQ_CHANNEL is blank, not 0, but somehow the lower level classes think they are being passed an badly formed MQCD.
I'm using MQ Client version 7.0.1.4
I've hunted through the docs for XMS and the .Net classes and I haven't seen anything that says this shouldn't work.
What am I missing?

Try the latest v 7.0.1.6 I believe there were some fixes in the XMS area since 7.0.1.4

I've upgraded to 7.0.1.6 but I get exactly the same behaviour and same error.

How exactly are you setting up your connection factory?

I'm just looking it up from the InitialContext. The settings are as you can see in the last code block, ie I have set the queue manager, host, port, connection type, left the channel blank, and everything else is default. I've set the ccdt url but that isn't read from the bindings file.
If I run it in managed connection mode, I get a 2059 (Q_MGR_NOT_AVAILABLE) through apparently this can be caused
"If the client channel fails to connect, perhaps because of an error with the client-connection or the corresponding server-connection channel definitions."
Again, if I specify a channel name, it all works fine so I don't believe there is an issue which the queue manager itself.

Ok ... if you are using a CCDT you should only set the qmgr name as defined in the client channel. Host, channel and port are provided by the CCDT.  client manual in the infocenter.
Have fun

Makes sense. However MQExplorer won't let me create a ConnectionFactory without a port set. Even if I then edit the file and blank or remove all the port entries, the ConnectionFactory loaded by my app still has Port set to the default 1414 and I get the same error.

Are you sure you are marking the right radio button on MQExplorer that says use CCDT?

I've done this:
ie set the CCDTURL and left the channel blank.
I see no other radio buttons I can set. |

Don't know which version you're looking at...
On my MQE/WMBE I choose:
Add remote qmgr --> use chltable --- fill in qmgr name
Next screen asks for the channel table location... nothing about a channel name...

| We finally solved this mystery, and the cluprit was MQExplorer. By using JMSAdmin we were able to create a .bindings file with the bare minimum of settings (ie no host, port or channel set), and this worked perfectly. |
