| In our system, there are often too many client connections occupied by the applications , therefore, no more connections can be established. I am wondering whether it is possible for MQ server to close the client connections which are not used for a specific time period. Thanks for your help. |

If the client connections are not used but valid, that is, there is still a live MQClient application on the other end, there is nothing you can set to automatically dump them.
If the client connections are orphaned, that is the MQServer has the connection open but there is no one home on the other side, what you can do is use KeepAlive. Make sure it is on for the QM, and then maybe lower the value from the default of 2 hours (its a server setting effecting all apps, not just MQ).
KeepAlive will dump those stale connections after KeepAliveTime.
The real problem is the client apps are just ending without closing the queues and issuing the MQDISC call. If they were doing that, the MQServer would know when they are ending and would then clean up the connection.
You could also set Heartbeats on the SVRCONN channel, but that will only help you if the MQClients are doing long MQGET with Waits, as heartbeats only flow during MQGETs for MQClient connections.

| Got the answer from other post. KeepAliveTime is for whole system! KeepAlive=true/false(to use it or not) |
