Dear All,
I have added the following lines in qm.ini file of production server becasue it was quickly required by client.
Channels:
MaxChannels=700
MaxActiveChannels=600
TCP:
KeepAlive=Yes
ListenerBacklog=700
Just clear me 2 things:
1- It is necessary to increase log file after these addition in qm.ini file ???
2- what are the possible impact / Issues may occure after these addition in qm.ini file. or what any other configuration changes are required after these changes ????

Don't double post! If you thought this was in the wrong place ask for it to be moved?

Why would you think that? What connection does the log have with these?

Isn't it a bit late if you've already made these changes? Didn't the client look into this before he urgently required these changes? Presumably the client had a reason, or a problem, and looks to this change to fix it? Why did you make the change if you don't know the impact, especially in production? If you made the change at the client's insistance, why are you worried about the consequences?

Why would you think that? What connection does the log have with these?Actually i m asking about No: of log file because i saw an error in application server logs which is putting messages on MQ queue. error shows the code "WMQ Reason : 2003".

I am asking this just for getting an expert opinion. i m an professional consultant for MQ. problem is that in the environment. i m working my client become more satisfied when some one from IBM support recommend the changes. no other issue. i know that no changes should be done direct on production.
I would be better if you provide me you expert opinion rather then digging out this type of things.
i hope you will take it positive.

I'd be surprised if this was a log problem. I'd suspect the application doesn't handle the connection changes too well, and is throwing 2003 as a result.

Then raise a PMR - we're not IBM and I doubt your client will be reassured by a bunch of volunteers on the Internet.

Not being able to get inside your head and know your thought processes, Vitor was covering questions etc. that any half-decent admin/designer would ask. It was only in your second post (or third  ) that you stated your depth of knowledge, and your first post was more akin to what a newbie might post.

I don't expect a great impact on your system by changing these values, but if these channels are really used it may exhaust memory, cpu-ressources, log space ...

Generally, if you change something for the QM via runmqsc, it takes effect immediately, whereas changes to the qm.ini file need a QM restart to pick up the change.
This guideline is not written anywhere in the manuals, and may not be 100% true, but its always worked for me.

Both with you and my most worthy associate.
I've never seen it written down anywhere (links welcomed) but I'd certainly follow any change to qm.ini with a bounce of the queue manager.

Not quite any... OCSPAuthentication values (in the SSL stanza) can be changed, and the resulting change picked up with a REFRESH SECURITY TYPE(SSL) command (I learned this the hard way  )
EDIT: Forgot to state V7.0.1 onwards...

Note the sneaky get-out: "...Any changes you make to a configuration file usually do not take effect until the next time the queue manager is started..."
