Viewing the status of a WebSphere MQ link and its components

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.

About this task

To view the status of a WebSphere MQ link, use the administrative console to complete the following steps:

Procedure

  1. In the navigation pane, click Service integration > Buses > [Content Pane] bus_name > [Topology] Messaging engines > engine_name > [Additional Properties] WebSphere MQ links
  2. Click the WebSphere MQ link you want to view.
  3. Click the Runtime tab. The content pane displays the status of the WebSphere MQ link.
  4. Click the Configuration tab.
  5. To view the status of the sender channel:
    1. Click Sender channel.
    2. Click the channel you want to view.
    3. 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.
    4. Click Saved batch status. The content pane displays the saved status of message batches that have been saved for transmission to WebSphere MQ.
    5. If a batch is in doubt, you can either commit or rollback the batch.
  6. To view the status of the receiver channel:
    1. Return to the WebSphere MQ link page.
    2. Click Receiver channel.
    3. Click the Runtime tab. The content pane displays the status of the receiver channel.
    4. 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.
    5. Return to the receiver channel page.
    6. Click Saved batch status. The content pane displays the saved status of message batches that have been received from WebSphere MQ.

What to do next
