Configuring Failover Alert 

Use

You can configure a failover alert message for your application that will appear in a small pop-up box on the screen. This happens if a server process within the Web AS cluster is marked for shutdown. The failover message warns you that the server will be shut down after a certain timeout period. This feature is critical for applications that are not failover-enabled. For those that are, failover is performed transparently and the user can continue working with the application. For more information about the session failover, see HTTP Sessions and Failover of Web Applications.

You can configure the failover alert using the web-j2ee-engine.xml descriptor.

Procedure

On the web-j2ee-engine.xml screen, proceed as follows:

...

       1.      Open the General screen.

       2.      Enter the time period (in minutes) when the alert is activated in the Minutes before server-shutdown field.

       3.      Enter the alert message that is to be displayed on the screen in the Message to display on alert field.
