    <p>I'm guessing the problem (or at least <em>a</em> problem) is here:</p> <pre><code>MQQueue mqQueue = new MQQueueManager(queueName, props); </code></pre> <p>This should be </p> <pre><code>queueManager = new MQQueueManager(queueManagerName, properties); </code></pre> <p>If you have installed the WebSphere MQ client to the default location, there are many sample programs under the following directory:</p> <pre><code>C:\Program Files (x86)\IBM\WebSphere MQ\tools\dotnet\samples\cs\base\ </code></pre> <p>There are a number of sample programs there for various tasks. If you have the latest V7.1 client installed then you will see the following programs:</p> <pre><code>SimpleAsyncPut SimpleClientAutoReconnectGet SimpleClientAutoReconnectPut SimpleGet SimpleMessageProperties SimplePublish SimplePut SimpleReadAhead SimpleSharingConversation SimpleSubscribe SimpleXAGet SimpleXAPut </code></pre> <p>There are also WCF and XMS samples.</p> <p>If you need the client code, please see my response to another SO question <a href="https://stackoverflow.com/questions/10957612/what-is-the-latest-websphere-mq-client-version/10957643#10957643">here</a> for links.</p> <p><strong>Update:</strong> </p> <p>Here's the normal diagnostic process.</p> <ol> <li>If the WMQ components were installed by relocating libraries or classes from somewhere else, perform an install using the full vendor-supplied client media. This includes troubleshooting utilities such as trace, dspmqver, etc. It also resolves any library or class mismatch issues.</li> <li>Use the pre-compiled client programs to test the connection. The <code>amqsputc</code>, <code>amqsgetc</code> and <code>amqsbcgc</code> programs require the <code>MQSERVER</code> environment variable <a href="http://publib.boulder.ibm.com/infocenter/wmqv7/v7r1/topic/com.ibm.mq.doc/cs12280_.htm" rel="nofollow noreferrer">as described here</a>. The Q program from <a href="http://ibm.co/SupptPacMA01" rel="nofollow noreferrer">SupportPac MA01</a> is a separate download but has the advantage of NOT requiring any environment variables, CCDT files or other dependencies.</li> <li>If the sample programs fail, check the QMgr's error logs at <code>[WMQ install]/qmgrs/[QMgr name]/errors/AMQERR01.LOG</code> for messages. Also check for FDC files and errors in <code>[WMQ install]/errors</code>.</li> <li>If no errors on the QMgr side, attempt the connection again while using a client-side trace as described <a href="http://publib.boulder.ibm.com/infocenter/wmqv7/v7r1/topic/com.ibm.mq.msc.doc/xms_ctrouble_trace_net.html" rel="nofollow noreferrer">here</a> and <a href="http://publib.boulder.ibm.com/infocenter/wmqv7/v7r1/topic/com.ibm.mq.doc/cs12880_.htm" rel="nofollow noreferrer">here</a>.</li> </ol> <p>Most client problems are resolved through installation of the full WMQ client as supplied by IBM. (Conversely that implies most people are installing by grabbing DLL or JAR files.) If the problem persists, error log inspection on the QMgr and client side usually reveals the underlying cause. If these do not work then tracing usually diagnoses the remaining issues.</p> <p><strong>UPDATE 2:</strong><br> Per the error messages <a href="http://www.mqseries.net/phpBB2/viewtopic.php?p=332547#332547" rel="nofollow noreferrer">posted at MQSeries.net</a>, the channel has a security exit set. A security exit is external code that the channel calls out to when starting a channel. There is no way to know what the exit expects or does without having access to the code or docs of the exit. If the exit is written in-house, you'll need to talk to the programmer to figure out what it requires. If the exit is a commercial product then you will need to get the documentation for it. </p> <p>Alternatively, alter the channel so that <code>SCYEXIT</code> is blank to disable the exit.</p> <p>The data posted at MQSeries.net was as follows:</p> <pre><code>MQ9575: DCE Security: failed to get the user's login name. EXPLANATION: System call 192.168.50.55 to get the login name of the user running WebSphere MQ client application process 5 failed with error value -1. This occurred in security exit function create_cred. The exit will now attempt to open channel using the DCE default login context. ACTION: If you wish to run using the DCE default login context take no action. If you wish to run using the user's login name as the DCE security exit principal examine the documentation for the operating system on which you are running MQ clients and reconfigure the operating system as necessary to allow the 192.168.50.55 call to succeed. </code></pre> <p>Note that it states the call is failing in the security exit.</p>

    1. COsorry about the typing error I just copied parts of the code. I don't believe its a code error because when I used the samples and the console of mq it still doesn't work. It gives me: MQRC_CHANNEL_CONFIG_ERROR how should I configure the server?

    2. COHow did you install the .Net classes? If they were installed with a WMQ Server, it is necessary to select the WMQ client components during the install. Also, the QMgr must have the channel specified and a running listener on the port specified. You can test this using the `amqsputc` program in `C:\Program Files (x86)\IBM\WebSphere MQ\tools\c\Samples\Bin`. You can also test using the Q program from SupportPac MA01 http://ibm.co/SupptPacMA01 If these work then you have a code issue. If not then its a config issue.

    3. COHi, thanks for the help. It still doesn't work with the same error - CONFIG_ERROR **What config error can it be?** I saw that MQRC_CHANNEL_CONFIG_ERROR is [one of these](http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/index.jsp?topic=%2Fcom.ibm.mq.amqzao.doc%2Ffm20910_.htm) but how do I solve these problems? and how do I know which one is it..
