More on 'orphaned' SVRCONN connections
Last night I made the change to include TCP: KeepAlive=Yes and CHANNELS: AdoptNewMCA=ALL/Check=QM,ADDRESS,NAME and recycled the Queue Manager.. (FYI the manual says you can use 'ALL' for the AdoptNewMCACheck parm, but MQ does not like it). These parameters were not used previously. This morning I have 10 times as many 'orphaned' connections to my SYSTEM.DEF.SVRCONN channel as yesterday (several hundred connections). Except for a few connections coming from its own server, all the connections are coming from PeopleSoft web servers (using JMS listeners). What must be done to get rid of these connections?

Hi Peter, Last night I made the change to include TCP: KeepAlive=Yes and CHANNELS: AdoptNewMCA=ALL/Check=QM,ADDRESS,NAME and recycled the Queue Manager..

Except for a few connections coming from its own server, all the connections are coming from PeopleSoft web servers (using JMS listeners). What must be done to get rid of these connections? I believe AdoptNewMCA is only meaningful with SDR/RCVR-type channels, not client channels. I believe KeepAlive is still the recommended approach to cleaning up orphaned client connections. Do you know what interval is specified? I believe the default on most IP stacks is 2 hours.

Re: More on 'orphaned' SVRCONN connections
I don't know what that interval is.. I'll have to ask a sysadmin. Its probably the default for AIX.

Re: More on 'orphaned' SVRCONN connections
Thanks.. At least I've got it set for the regular channels..

If the queue manager receives a request for a new connection, it will check to see if it already has a amqcrsta process running for that channel name. How it handles that request depends on if you have a AdoptNewMCA stanza in your qm.ini file or not. Client connections are not associated with the amqcrsta process, and are thus not effected by AdoptNewMCA.
