What Are The Trigger Monitors In MQ

Trigger Monitors
In MQ Trigger Monitors are 

1. Channel Initiator
2. Trigger Monitor

Channel Initiator

A channel initiator acts as a trigger monitor for sender channels, because a transmission queue may be defined as a triggered queue. When a message arrives on a transmission queue that satisfies the triggering criteria for that queue, a message is sent to the initiation queue, triggering the channel initiator to start the appropriate sender channel. You can also start server channels in this way if you specified the connection name of the partner in the channel definition. This means that channels can be started automatically, based upon messages arriving on the appropriate transmission queue.

How to start channel Initiator

• runmqchi -m qmgr-name  -q initq-name

Trigger Monitor

Trigger Monitor runs applications in response to a trigger event. When message(s) arrives on a application queue(local queue) that satisfies the triggering criteria for that queue, a message is sent to the initiation queue, now  trigger monitor starts appropriate application. 

How to start Trigger Monitor

• runmqtrm -m qmgr-name -q initq-name
