I am having AMQ9513 on iSeries and mq 6.0.2.5, but according to the documentation the MaxChannels variable is no longer used:
| Code: |
MaxChannels=100|number You can still use this stanza, but it is now ignored. Your system resources are the only constraint on the number of channels you can define.
|
The server has lots of free mem and cpu, so I don't know what should I do to avoid these issues. |

What does the documentation say about MaxActiveChannels?

These are the variables, I read them before posting, but that didn't help me.
| Code: |
MaxChannels=100|number You can still use this stanza, but it is now ignored. Your system resources are the only constraint on the number of channels you can define.
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.

What happens if you increase MaxActiveChannels (and restart the queue manager obviously)?

So the point here is that MaxChannels was a control over how many channel objects could be defined using mqsc or etc. This didn't seem to have a lot of value - who cares if you have defined 100000 channels if you only ever use one during runtime.
MaxActiveChannels is the number of channels that can be running at any given time, regardless of how many are defined at all. So if you are hitting any issues during runtime, they are because of a deficit in MaxActiveChannels, not in MaxChannels.
Or because of a well meaning developer who forgot to put MQDISC in an exception handling routine. |
