I wrote an application that connected to local queue using this
function call:
MQQueueManager mqQMgr = new MQQueueManager("QM_QueueName");
Now I need to connect to remote queue on another computer.
I can successfully connect to remote queue using MQ Explorer from my development PC using QM_ComputerName as queue name, S_ComputerName as channel and ComputerName as connection name. So it is accessible from my desktop.
However, when I try to connect via .Net I get MQRC_Q_MGR_NAME_ERROR no matter what I try.
I tried specifying
MQEnvironment.Hostname = "ComputerName";
MQEnvironment.Channel = "S_ComputerName ";
and then calling
mqQMgr = new MQQueueManager("QM_ComputerName");
I also tried calling
mqQMgr = new MQQueueManager("QM_ComputerName", "S_ComputerName", "ComputerName");
I get error in both cases.
Anyone can advise? |

Pedantically, you're connecting to a queue manager. Hence the class you're using.

Calling a queue manager a queue will confuse people. Like me. So what you mean is you're got the queue manager to appear in MQExplorer by using these values?

What kind of connection are you using? If you're still using a binding connection then that's not going to work.

It's a shorter way of asking my question about connection types, and also part of the answer. Look it up here

| Vitor: my original post was confusing. I did use "queue" instead of "queue manager". I updated original post to fix that. |

Yes, default port - 1414 |
And what was the outcome of the connection type question?

As I mentioned in my OP - I get MQRC_Q_MGR_NAME_ERROR no matter what I try. I think I just can't get argument right. |

No, I meant our question about what connection type you're using. NMQ_MQ_LIB and so forth. As above.

Oh, I see what you mean now. I don't set NMQ_MQ_LIB or MQC.TRANSPORT_PROPERTY explicitly. This could be the source for my problems. Call me dumb, but I looked at help article that you provided and I am still not clear how to specify them. Can you provide a sample code snippet? |

Almost certainly. As shown here, if you don't explicitly set a connection type it's decided based on if you have server installed or not. Your OP talks about a local queue manager, implying you hav. Hence you're getting a server connection which won't work for what you're trying to do.

Ok, you're dumb. 
NMQ_MQ_LIB is an environment variable. I suspect you won't have got this far through a programming career without setting one of those. The documentation (link repeated above for your convienience) says:
| Quote: |
You can specify the transport property as follows:
By setting the property MQC.TRANSPORT_PROPERTY in a hashtable entry on an MQQueueManager constructor:
public MQQueueManager(String queueManagerName, Hashtable properties) |
If you're still having trouble, code samples are supplied with the server install. If you didn't install them with the software check your media.

Until the previous post the fact that NMQ_MQ_LIB is environment variable (and yes, I did set a lot of them over my career) was not mentioned. Neither it was mentioned in the help article. However your responses did point me in the correct direction and this is how I got it to work - hope it will help someone in the future (setting NMQ_MQ_LIB is not needed):
| Code: |
MQQueueManager mqQMgr=null;
Hashtable props = new Hashtable();
props.Add(MQC.HOST_NAME_PROPERTY, "HostNameOrIP");
props.Add(MQC.CHANNEL_PROPERTY, "ChannelName");
props.Add(MQC.PORT_PROPERTY, 1414);
props.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_MANAGED);
MQQueue mqQueue = null;
try
{
mqQMgr = new MQQueueManager("QueueManagerName", props);
mqQueue = mqQMgr.AccessQueue(
QueueName,
MQC.MQOO_OUTPUT // open queue for output
+ MQC.MQOO_FAIL_IF_QUIESCING); // but not if MQM stopping
}
catch (MQException mqe1)
{
} |

And on behalf of those future readers I thank you for posting your solution.

This is true - it's an optional method perhaps more suited to a global connection solution.
Either way, glad you got it working.
