Controlling channel and bridge events

Channel events are controlled using queue manager attributes. To enable channel events, set the appropriate queue manager attribute to ENABLED. To disable channel events, set the appropriate queue manager attribute to DISABLED. To enable or disable channels events you can use the MQSC command ALTER QMGR specifying the appropriate queue manager attribute, as follows:

Channel events
Set the queue manager attribute CHLEV.

To specify that only the events related to channel errors are to be recorded, set CHLEV to EXCEPTION.

IMS Bridge events
Set the queue manager attribute BRIDGEEV.
SSL events
Set the queue manager attribute SSLEV.
Channel auto-definition events
Set the queue manager attribute CHADEV.

Channel auto-definition events are not available on WebSphere MQ for z/OS.
