This topic describes how you can view the status of a WebSphere MQ link and
its components, such as the sender and receiver channels.
Before you begin
You may want to view the status of a
WebSphere MQ link or
its components because:
- You intend to stop the WebSphere MQ link and
you need to see if there are any messages currently held on it.
- You are about to delete the WebSphere MQ link and
you need to verify there are no messages on it.
- Messages have not arrived at their expected destination and you want to
check if they are being held, pending transmission over the WebSphere MQ link.
Note: If
you attempt to start a WebSphere 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.
Why and when to perform this task
To view the status of a WebSphere MQ link, use the administrative console to complete the following steps:
Steps for this task
- In the navigation pane, click bus_name
- Click the WebSphere MQ link you
want to view.
- Click the Runtime tab. The
content pane displays the status of the WebSphere MQ link.
- Click the Configuration tab.
- 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 or not the message on the channel is in doubt. If the message
is in doubt, it has not been acknowledged by WebSphere 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 WebSphere MQ.
- If a batch is in doubt, you can either commit or rollback the
batch.
- To view the status of the receiver channel:
- Return to the WebSphere 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 WebSphere MQ.
You can also view the status of subscriptions for a broker profile
