Stopping the receiver channel on a WebSphere MQ link
You can stop the receiver channel on a WebSphere® MQ link while leaving the link itself running.
Before you begin
Note: If you stop the receiver channel on a WebSphere MQ
link, communication with the target IBM 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 might want to warn the administrator of the IBM MQ network that you are about to stop the channel.
About this task
If you stop a receiver channel, messages sent to the WebSphere MQ link engine are not received.
If a IBM MQ sender channel is started while an MQ link receiver channel is stopped, the request fails with an error indicating that the receiver channel is not available.
For more information about stopped states of the WebSphere MQ link and its channels, see Estados do Link do WebSphere MQ e seus Canais.
Procedure
- Start the administrative console.
- In the navigation pane, click .
- 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.
Results
Target state | Quiesce stop mode | Force stop mode |
---|---|---|
Inactive | The receiver channel moves to the stopping state and the data flow to the IBM MQ sender channel stops. When the IBM MQ sender channel next tries to communicate with the receiver channel the IBM MQ sender channel enters a state of retrying. The receiver channel then becomes inactive. The retrying IBM MQ sender channel then reestablishes a session with the receiver channel, and both channels become running. | The receiver channel immediately becomes inactive. When the IBM MQ sender channel next tries to communicate with the receiver channel, the IBM MQ sender channel enters a state of retrying. The retrying IBM MQ sender channel then reestablishes a session with the receiver channel, and both channels become running. |
Stopped | The receiver channel moves to the stopping state and the data flow to the IBM MQ sender channel stops. When the IBM MQ sender channel next tries to communicate with the receiver channel the IBM MQ sender channel enters a state of retrying. The receiver channel then becomes stopped, so preventing the IBM MQ sender channel from reestablishing a session. The IBM MQ sender channel itself then becomes stopped. | The receiver channel immediately becomes stopped. When the IBM MQ sender channel next tries to communicate with the receiver channel, the IBM MQ sender channel enters a state of retrying, and then becomes stopped itself. |
