Question

I have some strange problem. I think I followed documentation correctly but my code doesn’t work. I have this very simple hard coded test (NUnit):

[TestFixture]
public class MQQueueTests {

    public const string MessageContent = "<test>This is test message</test>";

    public static void Main(string[] args) {
        var tests = new MQQueueTests();
        tests.PutAndGetMessage();
    }

    [Test]
    public void PutAndGetMessage() {
        var properties = new Hashtable
                             {
                                 {MQC.HOST_NAME_PROPERTY, "TestServer"},
                                 {MQC.CHANNEL_PROPERTY, "Test.Channel"},
                                 {MQC.PORT_PROPERTY, 1415},
                                 // Is this correct? It looks like it is not 
                                 // enough because adding this line didn't solve 
                                 // the problem.
                                 {MQC.CCSID_PROPERTY, 437}  
                             };

        using (var manager = new MQQueueManager("Test.Queue.Manager", properties)) {
            using (MQQueue queue = manager.AccessQueue("Test.Queue", 
                MQC.MQOO_OUTPUT | MQC.MQOO_INPUT_AS_Q_DEF)) {

                MQMessage message = new MQMessage();
                message.WriteUTF(MessageContent);
                queue.Put(message);

                MQMessage readMessage = new MQMessage();
                queue.Get(readMessage);

                Assert.AreEqual(MessageContent, readMessage.ReadUTF());

                queue.Close();
            }
            manager.Disconnect();
        }
    }
}

I’m running the test application either from console or through Resharper 6 test runner. If I run the application in test runner I always get following exception:

IBM.WMQ.MQException : MQRC_CHANNEL_CONFIG_ERROR (reason code is 2539)

The exception is thrown by MQQueueManager.Connect (called by its constructor).

If I check MQ logs I see:

AMQ9541: CCSID supplied for data conversion not supported.

EXPLANATION: The program ended because, either the source CCSID ‘437’
or the target CCSID ‘852’ is not valid, or is not currently supported.

ACTION: Correct the CCSID that is not valid, or ensure that the
requested CCSID can be supported.

If I run the application from the console I got the same error but if I change the code page for console by calling

chcp 437

My test application works. How can I configure code page from code?

Answer 1

Well I found a workaround – it can probably solve my problem but I’m not very satisfied with it. I can set up MQCCSID environment variable either globally or by calling:

Environment.SetEnvironmentVariable("MQCCSID", "437");

That will configure code page. Still I would like to use properties of a new MQQueueManager instance to setup code page.
