# Start a new server with Astor

{audience}`administrators, developers`

## If the server is already defined in database

- Be sure that a {program}`Starter` device server is running on the same host.
  If there is no {program}`Starter` running, start it.

- On {program}`Astor` main window, click on the host to open {doc}`host window <host_window>`.
  On this window, click on {guilabel}`Start New` button.

- A window with a list of all servers defined in TANGO database will be
  displayed.

  ```

## If the server is NOT already defined in database

- You can declare the server in database using
  [Jive](inv:jive:std#index).
- Or click on {guilabel}`Create New Server` button to start the
  {doc}`wizard <new_server_wizard>`.

## If the server has been started from shell

The default startup level is not set and the server is not controlled
by Astor.

That means that it does not appear in {doc}`host window <host_window>`.

To see it click open **Not Controlled** level.
And change it startup level if needed.
