Stop the Other Application Server

You inform all the active users on an application server to move to the less active application server before you stop it. Ensure that you have restarted the less active application server before moving all the users to it.

Follow these steps:

1. (Recommended) Inform all active Support Automation analysts on the application server which you want to stop, to create a ticket in CA SDM with their session information. This process ensures that the session information is not lost. For example, the Support Automation analyst is in a session with a customer to resolve a hardware issue. In such a case, the Support Automation analyst can create an issue in CA SDM with the session information before the application server shuts down.
2. Send a notification (for example, an email notification) to all the active users on the application server to move to the less active application server that you just restarted. This notification can include the details of the updated application server.
3. Execute the following command on the application server:

   pdm_server_control [-h] -q interval -s server_name
   

   -h

   Displays the help page.

   -q interval -s server_name

   Notifies a local or remote application server to quiesce in a specified time interval.  This interval is the number of seconds before the server goes offline. When using this option without a server_name, the local server is notified to quiesce. This option cannot be used for a background or a standby server.

   A pop-up message is displayed to all the active users on the application server to notify them about the server shutdown and the time left for the shutdown. The users must save their work and logout within that time. The application server stops after the specified time. The users log on to the other application server to resume their work. The Support Automation analyst can refer to the ticket and resume their work.

   The application server is stopped successfully.
