Our developers are in the infancy stages of creating applications to communicate through WMQ and I have a question as an administrator trying to get my head around this. I believe they will be communicating through application queues created locally for each tied to the QM. Will they also require a svrconn channel def for each of those applications as well ? I've seen that noted in one the forums. I'm trying to connect the dots between the application through the local QM to the other end. Trying to make sure that all the pieces are configured. Any help appreciated. We have clustered QM's.
Currently, I have a QM, QM alias, DLQ, NL, cluster rcvr and sdr chl's created, and admin svr conn.
Thanks |

The NL doesn't provide any help, unless you have a specific reason for it that you've not mentioned.
The only question that determines whether the applications will require a svrconn is what machine they will run on.
If it is the same machine as the queue manager, then the apps will not strictly require a svrconn. they may choose to use one, or you may choose to force them to use one, but it is not technically required.
If it is not the same machine, then they must use a svrconn to connect to some queue manager - the one that hosts the qlocal copies of the queues they need to read from. |

The (NL) namelist is used for our cluster naming. We have a dev, test, and prod cluster. The applications will run on the same box (as400) as the local QM, but will communicate to other boxes (as400) with their own local QM. at least in the prod environment. In test and dev, the QM's are all local, just pointing back to the same box. The full repository QM's, are hosted on other servers for all three environments.
I wasn't sure how the svrconn chl was going to be used. We want to run the applications under a group id assigned in application(not associated with end user running app) and have the proper authority to the QM and queues established.
So, do I have all the pieces to this puzzle ? Sorry, i'm a newbie to this stuff.

I think you'll find that AS400 apps, or even almost any other app on OS400 can't actually make client connections.
And I also think you'll find that cluster namelists cause problems in the long run. |

Unfortunately not. We got a quick overview from a vendor who came in and performed implementation services, but it was far from thorough. That's why I've headed to this forum to find some answers. |

You won't get much help from this forum if you have not taken your own initiative.
Taking your own initiative can include reading the InfoCentre and going to class. People here frown on you if you don't do the homework and expect us to bail you out. We won't write your code for you if you don't invest in yourself first.

Sorry, to offend, but I'm not asking for anyone to write any code or bail me out. I'm asking some basic questions about setup and configuration from someone who hasn't been there and administered MQ for 5+ years as I expect you have. Forums are for asking questions about issues you don't have answers for, so sorry if a newbie has asked too many questions. As for the infor center, I've been there, but the pieces haven't come together for me as I have liked. As for training.. that's only if you had enough prep time and funds made available to you prior to being given this task. Please don't assume you know everything about what homework I've done before coming here to this forum. All I'm looking for is some informative answers.
Thanks |

Which you find the answers to in the InfoCentre or the class.
What stops you from registering for the class today?

The suggestion is to be careful of how you ask things.
This is a place to receive assistance, but it's not a place to receive instruction.
So if you explain your situation clearly and explain the steps you've taken, you'll find that it's a better response than if you merely ask how to do something. |

At least the last time I used AS/400 they couldn't. Though that was a few years ago. I do observe the WMQv7 client documentation doesn't mention AS/400

At least until you have more experience with the WMQ software & topology.

Assuming that the applications can use a SVRCONN then yes you do.
