Event Monitoring: Channel Started

Channel Started

Event name: Channel Started.

Reason code in MQCFH: MQRC_CHANNEL_STARTED (2282, X'8EA').
Channel started.

Event description: Either an operator has issued a Start Channel command, or an instance of a channel has been successfully established. This condition is detected when Initial Data negotiation is complete and resynchronization has been performed where necessary, such that message transfer can proceed.

Event type: Channel.

Platforms: All, except WebSphere MQ for z/OS if CICS is used for distributed queue management. Client connections do not produce this event.

Event queue: SYSTEM.ADMIN.CHANNEL.EVENT.

Note:

MQSeries for Windows V2.1 does not define the channel event queue for you, so the default action is not to generate channel events. This is because, once you have defined a channel event queue, you cannot stop channel event messages being generated. If you want WebSphere MQ to generate channel events, define the channel event queue yourself using the name SYSTEM.ADMIN.CHANNEL.EVENT.
