When you configure
a service or service group, you either modify an existing service or service
group, or add new services to the AppExpert application. You add services or
service groups if you did not specify them when you imported the application
template. You also add services and service groups when you increase the number
of servers that host instances of the application. You can configure a service
and service group for an application unit only after you configure the service
or service group for the AppExpert application.
