Channels are designed to be active only when there is work for them to process. This mechanism allows for conservation of limited system resources such as active transactions and LU 6.2 sessions while at the same time delivering messages in a timely fashion determined by the application. The mechanisms which are used to determine when a channel is started and stopped are triggering and the disconnect interval respectively.
This mechanism works well unless the operator wishes to terminate a channel before the disconnect time interval expires. This can occur in the following situations:
In these cases it is necessary to stop the channel using the STOP option from the Message Channel List panel of the CKMC transaction. For information about what happens when a channel is stopped in this way, and how to restart the channel, see Stopping and quiescing channels.
