# Control graceful shutdowns

A graceful shutdown gives WebLogic Server subsystems time to complete certain application processing currently in progress. See ``Graceful Shutdown`.`

To control the length of the graceful shutdown process:

1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
2. In the left pane of the Console, expand Environment and select Servers.
3. In the Servers table, click the name of the server instance you want to configure.
4. Select Control > Start/Stop.
5. If you want the server's graceful shutdown to drop all HTTP sessions immediately instead of waiting for them to complete or timeout, select the check box Ignore Sessions During Shutdown.

   Waiting for abandoned HTTP sessions to timeout can significantly lengthen the graceful shutdown process because the default session timeout is 24 hours.

   The Graceful Shutdown Timeout field specifies a time limit for a server instance to complete a graceful shutdown. If you supply a timeout value, and the server instance does not complete a graceful shutdown within that period, WebLogic Server performs a forced shutdown on the server instance.

6. To limit the amount of time the server takes to complete a graceful shutdown, enter the maximum number of seconds in the Graceful Shutdown Timeout box.

   If you supply a timeout value, and the server instance does not complete a graceful shutdown within that period, WebLogic Server performs a forced shutdown on the server instance.

   If you do not supply a timeout value, the server waits indefinitely to complete a graceful shutdown.

7. Click Save.
8. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
   Not all changes take effect immediately—some require a restart (see Use the Change Center).
