Ahn... these "grep", "tail" commands... are for Linux, right?
I´m using windows. =( |
So what! Go get GNU utilities for Win32 and you will be able to do those commands too.

I use them all all the time on Windows.

Connections in MQ usually refer to programs MQCONNected to a qmgr. This has no impact on the number of channels.
Your qustion about how to decide the appropriate number to expand the channel status table (active) and maximum (maximum) has to do with the number of channels that connect one qmgr to another qmgr. No guesswork here. Count the number of channels you plan to implement; then add that.
Or am I completely misunderstanding this post? This is possible. |

Svrconn/clntconn channel pairs count against MaxActiveChannels.
MaxChannels isn't enforced except on zOS.

I´m sorry but I don´t understand what you mean. 
What I mean is: some days ago I counted the connections that were active in each channel (not a nice work to do). Totally there were 198. My MaxActiveChannel was set to 200.
Later that day, we received message "Maximum number of channels reached." I guess that happend because the number of connections went over 200. Right?
People are asking me if there is a way I won´t have to count the connections mannualy... channel by channel. They want it displayed somewhere... but i cannot find out how. If there was an easier way to do that we wouldn´t have waited the connections to reach 198 and then 200.
I´m sorry to bother you guys... i cannot download the gnu utilities. It´s a big company... they have rules... And I sooo don´t know MQseries as you.
Well, complicated.
Again, thank you for answering my post! |

How many channel definitions have you created? What kind?
What applications? MQ client conn? WAS? .NET? JMS? Something else?
Is this a brand-new issue for you? If so, what changed? |

I'd guess this is a client connection issue, and would suspect a badly behaved app is not dropping the connections it's finished with.
And yes, I know that's obvious to a lot of people. But possibly not everyone.
If this is a brand new issue then the question "what changed" is especially relevant, particually if there's been a code release recently!

There are receiver, server connection and sender, but mostly server connection.
MQ Clientconn.
Nothing changed and yet it is a new issue. |

We just use the free MO71 suppot pach which makes it very easy to see what the total # of active channels are, the # of a particular named channel, the # from a particular IP, the # of anything-channel-parm-you-can-think-of.
That works for a manual check.
For automated alerting we built a script on windows (I can post it if you want tomorrow) that counts the channels every few minutes. If its over our threshold we put a message to a queue and QPASA fires us an email when that q depth goes up by 1.
We also opened a request to MQSoftware to beef up QPASA to include monitoring and alerting for channel counts. Seems like a pretty basic requirement. I was surprised when we found no way to do it in the current release of QPASA.

That is surprising.

So.. I found it on Candle.
It´s not exactly what I wanted but it helps me a lot. It gives the connections by type of channel and since we have mostly server connections it´s now easier to count them.
Thank you very much! |
