I have successfully run the compiled C# sample "SampleConsumer.cs" on our MQ Server, and it works a treat, I can see it connect to the queue manager and download messages from the specified queue.
However, if I try to run it on a client system, it doesn't work.
Someone has told me that, in order for this to work, I need to configure a server connection (SVRCONN) channel setup.
I have no idea what this is, can anyone advise on where to start?
Thanks. |

You'll find full details on configuring a client connection in the Clients manual (or matching part of the InfoCenter).
You'll also need to relink your code to use client libraires. You'll find that described in the Clients manual, and detailed infomation on the connection types in the .NET manual.
Or you could just search the InfoCenter for "SVRCONN" or "server connection".

Ok, so I've found the clients section of Infocenter. I've got as far as the verification, but I get this error in the LOG file:
| Code: |
04/01/2012 09:35:51 - Process(2328.1) User(graffr-adm) Program(amqsputc.exe)
Host(AVN-AS-30-R)
AMQ9547: Type of remote channel not suitable for action requested.
EXPLANATION:
The operation requested cannot be performed because channel 'TAS_AMC1.AMC_EGW1'
on the remote machine is not of a suitable type. For example, if the local
channel is defined as a sender the remote machine must define its channel as
either a receiver or requester.
ACTION:
Check that the channel name is specified correctly. If it is, check that the
remote channel has been defined correctly.
----- cmqxrfpt.c : 457 -------------------------------------------------------- |
How do I define the remote machine's requester channel? I can see a section named Defining a client-connection channel using MQSERVER but I don't understand why it doesn't specify anything relating to the remote machine that is trying to make the connection. I'm imagining that I will need to tell the queue manager TAS_AMC1 to expect connections from my client AVN-AS-30-R. |

Ok, so I noticed that we'd set up a sender channel for our client, so I created a similar sender channel for my client machine. I've specified the IP address of my client machine, and the queue that I want to connect to.
Unfortunately, when I run the CS sample, I still get error 2035 (07F3) (RC2035): MQRC_NOT_AUTHORIZED.
Any idea why?
I've also tried this command:
| Code: |
amqsputc AMC_EGW1 TAS_AMC1
|
...but I get
| Code: |
| MQCONN ended with reason code 2058 |
..MQRC_Q_MGR_NAME_ERROR, which seems to imply that I got the queue manager name wrong, but I'm sure that TAS_AMC1 is the name of the queue manager.
Any ideas? |

The thing that perhaps I'm getting confused about, as I read the documentation, is that the manuals talk about setting up connections from local queue managers to remote queue managers, however, this isn't what I'm trying to do.
All I need to do is run the C# sample (or something similar), to read messages from the queue from a remote machine.
In case it's relevant, I am able to ping the MQ server via IP address from my client machine. |

You can only ever read messages (MQGET) from a local queue.
Messages may arrive on that local queue as a result of being put to a remote queue somewhere else.
If you are using a client connection to a "remote" QM, the queue is still local as far as MQ is concerned. |

Ok, so then I guess the question is, how do I set up my "local queue" on my client? Is this not what my new sender channel is doing? |

Am I barking up the wrong tree by using amqsputc to verify my set up?
I ask, because amqsputc seems to imply that I'm trying to put a message on a queue. This isn't what I'm trying to do. All I need to do is read messages from a queue. |

Not sure if this is relevant, but we have set up:
- 1 Queue Manager
Under queues:
- 8 x local queues
- 2 x remote queues
Under Channels:
- 2 x Receiver Channels
- 1 x Server-Connection (SVRCONN) Channel
- 2 x Sender Channels linked to Queue 1 (AMC_EGW1)
- 1 x Sender Channel linked to Queue 2 (AMC_EGW2)
One of the sender channels linked to Queue 1 is a TCP channel, linked to my client's IP address via port 1414. |

You need to read the Intercommunication manual more closely, especially the section on client applications. You need to delineate more clearly what you mean by client - do you mean client applications, i.e. applications invoking WMQ client libraries, or do you mean client queue managers, i.e. queue managers receiving messages from your queue manager, or do you mean clients, i.e. business partners to whom you connect, or connect to you, via WebSphere MQ infrastructure?
SENDER\RECEIVER channels are for queue-manager-to-queue-manager communication; SVRCONN channels are for client applications.
As you have found the PUT sample, go seek and find the GET sample

Channels do not link queues, channels link queue managers.

Hi Exerk, sorry for any confusion, I definitely mean client applications, as apposed to client queue managers.
Currently, we have two channels set up which both have SVRCONN in the name. One, which already existed before today, is of channel type "Server-connection", and is running.
The other, is the sender channel that I set up earlier today, which I named "REMOTE.SVRCONN". I'm guessing that I don't need this one.

Ok, well this is interesting, if I run
| Code: |
| amqsget AMC_EGW1 TAS_AMC1 |
i get this error:
| Code: |
| This application has failed to start because MQM.dll was not found. Re-installing the application may fix this problem. |
If I run
| Code: |
| amqsgetc AMC_EGW1 TAS_AMC1 |
I get this error:
| Code: |
Sample AMQSGET0 start
MQCONN ended with reason code 2058 |
So, to clarify, we do have a Server-Connection channel set up, and it is running. Is there something else I need to do, in order to allow my client application to connect? |

| If by client, you mean MQ client - these don't hold queues. |

Channels do not link queues, channels link queue managers. |
I see now that this is wrong, so I will delete this channel. |
