Hi,
Can anybody guide me on how to check max no of possible SVRCONN connections configured?...we don't have any such parameter set in qm.ini/mqs.ini.
But still when web server starts sending messages, i am able to see multiple instances of JAVA.CHANNEL of type SVRCONN running and after some time web server connection to MQ goes down. And MQ log shows max no of channel reached.
Regards |

First, off.
The name "JAVA.CHANNEL" is entirely useless. Don't use it, don't allow your developers to use it.
Second off, MQ does not have a built in way to limit the number of connections on a particular channel.
If you search around, you'll find that there are solutions available. If it's a production system, you probably want to put in a solution that is adequately supported for production use.

You should search for MaxActiveChannels parameter in ini file to see max active channels.

If you need this functionality you can do it with security exit.

we don't have any value set for MaxActiveChannels in ini file. Thats why i was interested to find out if MQ use any default no.
Jeff, JAVA.CHANNEL is created to identify and separate message traffic sent to MQ Queue Manager from particular application adapter. Can you pls clarify why we should avoid using it? |

Becuase it should be named after the application adapter, not after a programming language.

The limit on the maximum number of channels applies to all channel connections to a queue manager (svrconn, senders, etc all combined).
The default is, I believe, 100. If you want to allow more connections in total, it must be added to the configuration of the queue manager. The method depends upon the operating system. I believe all platforms require the queue manager to be recycled for the new parameter to take effect. |
