You might want to view the status of a WebSphere® MQ link or its components because you intend to stop the IBM MQ link and you want to see if there are any messages currently held
on it, or you are about to delete the IBM MQ link and you have to verify there are no messages on it, or messages
have not arrived at their expected destination and you want to check
if they are being held, pending transmission over the IBM MQ link.
About this task
To view the status of a IBM MQ link, use the administrative console to complete the following steps.
Note: If
you attempt to start a IBM MQ sender
channel that is already in RUNNING state, the WebSphere Application Server administrative
console might occasionally incorrectly report the channel status as
INACTIVE. If this happens, you can ignore the error because the channel
is still running. To return the channel status to RUNNING, stop and then restart the channel.
Procedure
- In the navigation pane, click one of the following paths:
- Click the IBM MQ link you want
to view.
- Click the Runtime tab. The content pane displays the status of the IBM MQ link.
- Click the Configuration tab.
- Optional: To view the status of the sender
channel:
- Click Sender channel.
- Click the channel you want to view.
- Click the Runtime tab. The content pane displays status information for the sender
channel. Some of the more important fields to check are:
- The status of the channel.
- Whether the message on the channel is in an indoubt state. If the
message is in doubt, it has not been acknowledged by IBM MQ.
- The number of messages in the current batch.
- The number of batches that have been sent.
- The time and date at which the channel was last started.
- The time and date at which the last message was sent.
- Click Saved batch status. The content pane displays the saved status of message
batches that have been saved for transmission to IBM MQ.
- If a batch is in an indoubt state, you can either commit or rollback
the batch.
- Optional: To view the status of the receiver
channel:
- Return to the IBM MQ link page.
- Click Receiver channel.
- Click the Runtime tab. The content pane displays the status of the receiver channel.
- Click Receiver channel connections. The content pane displays the connections existing on
the receiver channel, and their current status. You can stop connections
if required, by selecting the check box next to the connection and
clicking Stop.
- Return to the receiver channel page.
- Click Saved batch status. The content pane displays the saved status of message
batches that have been received from IBM MQ.
