This topic describes how to stop the sender channel on a WebSphere
MQ link while leaving the link itself running.
Note: If you stop the sender channel on a WebSphere MQ link, communication
with the target WebSphere MQ network on that channel will cease for both point-to-point
messaging and publishing and subscribing. Messages will be held at their transmission
locations.
You may wish to warn the administrator of the WebSphere
MQ network that you are about to stop a channel.
To stop the sender channel on a
WebSphere MQ link use the administrative console to complete the following steps:
- In the navigation pane, click bus_name engine_name link_name.
- Click the sender channel you want to stop.
- Select the check box next to the channel you want to stop.
- In the Stop mode list, select Quiesce or
Force.
- In the Target state list, select Inactive
or Stopped.
- Click Stop.
Only the sender channel is affected by this procedure. The resultant
state of the sender channel depends on the options you chose:
|
Stop mode |
Quiesce |
Force |
Target state |
Inactive |
The sender channel becomes inactive either when it has
finished processing its current batch, or when it reaches a heartbeat interval. |
The sender channel immediately becomes inactive. |
Stopped |
The sender channel becomes stopped either when it has
finished processing its current batch, or when it reaches a heartbeat interval. |
The sender channel immediately becomes stopped. |
For more information on stopped states of the WebSphere MQ link
and its channels, see States of the WebSphere MQ link and its channels.
Once you have stopped the WebSphere MQ link sender channel, messages
about to be sent from the WebSphere MQ link engine
are held back on the transmission queue.
