Restarting a Server in Quiesce Mode from Integration Server Administrator
You can restart an active or quiesced Integration Server in quiesce mode from the Integration Server Administrator.
To restart a server in quiesce mode from
Integration Server Administrator1. Open the Integration Server Administrator if it is not already open.
2. Click 
> Shut down or restart. 3. On the Shut down or restart page, select whether you want the server to wait before restarting or to restart immediately:
After all client sessions end. Specify the number of minutes you want the server to wait before restarting. The server begins monitoring user activity and automatically restarts in quiesce mode when all non-administrator sessions complete, or when the time you specify elapses, whichever comes first.
Immediately. The server and all active sessions terminate immediately. The server then restarts in quiesce mode.
Note:
The assets and activities that you have selected on the Server > Quiesce page are disabled even when you restart the server.
4. Click Restart in Quiesce Mode.
5. When you are prompted to confirm that you want to restart the server, click OK.
6. If you are running Integration Server Administrator from a port other than the quiesce port, stop Integration Server Administrator and start it using the quiesce port.
Integration Server displays a message at the top of all pages in the Integration Server Administrator indicating that the server is running in quiesce mode.
Note:
If the server cannot disable or suspend an asset or activity as it enters quiesce mode, the server displays a warning message and continues the quiesce process. If the condition stated in the warning interferes with a maintenance task you intend to perform, resolve the issue stated in the warning and then restart the server in quiesce mode.
