Viewing and closing connections to applications

We can use the Application Connections dialog to find out which applications are currently connected to a specific queue manager, and which queue manager objects an application is currently accessing. We can also use this dialog to close a connection.

About this task

Before you delete an IBM MQ object, or change its attributes, check whether any applications are currently connected to the queue manager or accessing its objects. The Application Connections dialog displays the applications that are currently connected to a specific queue manager, and which queue manager objects the application is currently accessing.

We can use the Application Connections dialog to close a connection. Be aware that when you close a connection between an application and a queue manager, the application can no longer access any of the queue manager's objects. This might prevent the application from working correctly.

To view a list of the applications that are connected to a queue manager:

Procedure

1. In the Navigator view, right-click the queue manager, then click Application Connections. The Application Connections dialog opens.
2. In the Application Connections dialog, the first table lists the applications that are currently connected to the queue manager.
3. Click an application to display, in the second table, a list of the objects on the queue manager that the application is accessing.
4. Optional: Close a connection:
   1. Click the name of the application, then click Close Connection.
   2. When you are prompted, click Yes to confirm to close the connection.
   The connection between the application and the queue manager is closed.

Results

If you closed a connection, the application that used that connection can no longer access the queue manager's objects.
