Hello everyone,
I'm currently facing a problem with amqmdain on Microsoft Windows and MQSeries V6.0.2.1. (French). It seem that the amqmdain reg function for a specific Queue Manager does not support the "CHANNELS" stanza keyword. It only work if I don't specify a Queue Manager.
Working example :
amqmdain reg * -c add -s CHANNELS -v MaxChannels=256
Not working case:
amqmdain reg TEST -c add -s CHANNELS -v MaxChannels=256
Any ideas ?
Best regards,
Jean-Marc

You probably want MaxActiveChannels, since MaxChannels isn't used on anything other than zOS.

According to the MQSeries Admin guide for the distribute platform V6. The MaxChannels as well as the MaxActiveChannels is a valid stanza argument.
Following is from the documentation:
Channels
Use the Channels queue manager properties page from the WebSphere MQ Explorer, or the CHANNELS stanza in the qm.ini file, to specify information about channels.
MaxChannels=100|number The maximum number of channels allowed. The default is 100.
MaxActiveChannels=MaxChannels_value The maximum number of channels allowed to be active at any time. The default is the value specified on the MaxChannels attribute.
MaxInitiators=3|number The maximum number of initiators.

More over,
The command amqmdain reg * -c add -s CHANNELS work when it should not since CHANNELS is normaly a qm.ini keyword and do not belong to mqs.ini.
In Microsoft Windows term : registry specific to a QManager and not to all Queue Manager.
I also notify that the Explorer (eclipse base tool), is working fine i.e. I can specify CHANNELS properties under a specific Queue Manager and not at MQSeries level....

That doesn't mean that it's USED.
I admit, the documentation is unclear on this. The only place it's really spelled out is in the iSeries guide. I've filed feedback to get this corrected - maybe it will be someday.
But believe me. MaxChannels is not used on any platform other than zOS. You can set it all you want.
And yes, it's possible that amqmdain has some bugs.

This is weard and perhap your right. I alway set both MaxChannel and MaxActiveChannels on windows and Unix. The documentation state that when MaxActiveChannels is not specify the default value is equal to the value specify for MaxChannels.
Since the limit on the distributed is 100 channels I often use these parameters to overwrite and increase the default.
Regards,
Jean-Marc

Hello everybody,
I found (keep trying), that if you put the keyword CHANNELS as Channels it will work find...
amqmdain reg TEST -c add -s Channels -v MaxChannels=1000
work fine,
more over, if you do the same command replacing the queue manager name with *, the command will be rejected stating that Channels is not valid for all Queue Manager. Although, if you replace the keyword with
amqmdain reg TEST -c add -s CHANNELS -v MaxChannels=1000, it will work.
I believe a code review should be done by our IBM frends,
Regards and thanks to all of you who spend time looking at my problem.

I found why the original problem was confusing; the value CHANNELS is case sensitive on windows, and must be entered as Channels instead!
fails;
AMQMDAIN reg * -c add -s CHANNELS -v MaxChannels=256
works;
AMQMDAIN reg * -c add -s Channels -v MaxChannels=256
You can check it in the registry with this;
regjump MyComputer\HKEY_LOCAL_MACHINE\SOFTWARE\IBM\MQSeries\CurrentVersion\Configuration\Channels
However, I still wonder if it should be set for the exact QM, and if both values need to be set.
On my W2k box, under \Configuration\QueueManger\QM_NAME\Channels reg key, I now have two values. MaxChannels=50 which is there by default, and a new MaxActiveChannels=350 which I set. Which will be used, and should I change the 50 to match the 350 value?
This is my first post, so many thanks!

This is kind of weird...
I'm currently using MQSeries Version 6.0.2.1 and my PC is running XP pro. Now that I use amqmdain reg TEST -c add -s Channels -v xxxxxx=yyyy, I get no more problem as I stated in a previous post. But I don't get the same registry key as you are mentionning...
Here is what I have : HKEY_LOCAL_MACHINE\SOFTWARE\IBM\MQSeries\CurrentVersion\Configuration\QueueManager\TEST\CHANNELS
The key is CHANNELS in upper case !
Can you check your MQSeries version.
MaxActiveChannels is realy what MQSeries will allow to run (be active) at a giving time.
Regards

I am running MQ 5.30.7
C:\>MQVER
Name: WebSphere MQ
Version: 530.7 CSD07
CMVC level: p530-07-L040527
BuildType: IKAP - (Production)
Getting ready to roll out v6.0.2.0 to 8 factories, so I will test the results there also.
Both times I tried * and the QM_NAME, with the upper case CHANNELS value, it would fail. With Channels, mixed case, both work. Both reg keys already existed as \Channels\ and the new REG_SZ value are the mixed case value I set.
BTW, when Windoz reads the reg, it does not care what the case is, however the MQ program may. If it is working and you can change the value and it shows up in the gui (eclipe for you, mmc for me on 5.3) than all should be well.
Cheers. |
