VHost Restart
lets you restart a virtual host. Restarting a virtual host disconnects all users of that
virtual host and removes all application instances from memory. If you are a server administrator
you can restart any of the server’s virtual hosts except the default virtual host (_defaultVHost_).
To restart a virtual host, enter its name in the Adaptor/VHost text box and click Restart. If you
are a virtual host administrator, you can only connect to and administer your own virtual host.
Click Restart to restart the virtual host.
Start lets you start a virtual host that has been previously stopped. This button is available only to
server administrators. If you are a server administrator, you can start any of the server’s virtual
hosts except the default virtual host (_defaultVHost_). To start a virtual host, enter its name in
the Adaptor/VHost text box and click Start.
As a security feature, virtual host administrators are not allowed to start a virtual host that has
been stopped.
Stop lets you stop a virtual host. This button is available only to server administrators. Stopping a
virtual host disconnects all users from that virtual host and prevents future connections. If you
are a server administrator you can stop any of the server’s virtual hosts except the default virtual
host (_defaultVHost_). To stop a virtual host, enter its name in the Adaptor/VHost text box
and click Stop.
Server Restart lets you restart the server. This button is available only to server administrators.
Restarting the server disconnects all connected users and unloads all application instances on all
virtual hosts from memory. A restart also reloads the server’s configuration files, allowing any
manually entered changes to those files to be read by the server.
Shutdown lets you exit from the server. This button is only available to server administrators.
When you use the Shutdown button, the server unloads all application instances and cleans up all
streams and other shared objects that the applications may be using. Shutting down can take a
few seconds while the server performs this cleanup procedure. When the server is shut down, the
Administration Console is disconnected.
Halt Now allows you to force the server to shut down immediately without any cleanup of streams
or shared objects. This button is only available to server administrators. Because the server
terminates without cleanup, data from all applications in memory will be lost. Therefore, use
Halt Now only when other methods of unloading applications, stopping virtual hosts, or
stopping the server fail.
Messages appear at the bottom of the Maintenance panel to indicate the success or failure of each
operation you perform.
