MQSeries.net :: View topic - CKTI: how to auto re-start CKTI. CKAM?

I encountered a problem in my test environment and this question came to me.

Here is what happened.

Application team called up telling me their messages are not triggering their CICS transactions. I checked the definitions of the queue, the process, the INITQ, the channel. Nothing wrong, but messages were stuck in local queue. Only then did I go to check CKTI in CICS region and found that CKTI was not running (nothing in CKQC "Display CKTI panel", but CKQC->Connection->Display still showed "CONNECTED").

I then manually started CKTI using CKQC->CKTI.

Then later on, for some question from application team, I went to check the user id of those triggered transactions in CICS region, I found the user ids are all my own personal ID. Then I realised it was because CKTI was restarted using my own personal ID.

This posed a question to me: how CKTI should be re-started in PRODUCTION?

I looked through WMQ set-up manual, I think it doesn't tell me how, only tells me how to start it together with CICS. Administration manual also doesn't have this info. I searched in the forum, found a similar post (http://www.mqseries.net/phpBB2/viewtopic.php?t=32844&highlight=ckam+ckti), but no one provided a reply.

To answer this question myself, I found there is a transaction CKAM whose description is "WebSphere MQ - Alert monitor". I can also find CKAM is running in some of our test CICS regions, but not in the region where CKTI stopped and I manually started. I think CKAM is monitoring CKTI and can re-start CKTI if CKTI is not running. So, there is another question coming to me: how CKAM is started?

Appreciate any advice on the 2 questions. Thanks.
