Websphere application server not closing MQ server connection channel, if no load is there.
Do any parameter needs to be set at MQ level to close the unused connections. |

You need to check and eventually set the discint paramater to a desidered numerical value ,probably your channel never disconnects because discint
(disconnect interval) has a zero value... |

If a SVRCONN is being used, that attribute is only valid on z/OS. That said, just because there is no 'load' does not necessarily mean the WAS instance should disconnect - in client terms it is not invalid to connect and stay connected.

Hello ,
i would like to see the output of the command DSPMQMCHL
when done on the channel that never disconnects .
However this type of behaviour could be right ,if we consider the potential performance issues of disconnect and reconnect
as exerk rightly pointed out . |

There's no particular reason that WAS would disconnect from a queue manager during a period of 'inactivity'.
Among other things, if there are Message Driven Beans, then WAS needs to stay connected in order to drive those beans as soon as messages arrive. |
