Before continuing with additional Sybase installations, Sybase recommends that you back up the Sybase Central repository file after installing WorkSpace and the developer edition servers.
To back up the repository file
Locate the following file:
<installation directory>\DevRuntimes\Shared\Sybase Central 4.3\.scRepository
Back up the file.
Verify that the EAServer plugin is registered. If it is not registered, manually register the plugin.
