Identifying Server Service Classes

Some service classes are server service classes, that is they are service classes representing address spaces doing work on behalf of transactions. You can determine whether a service class represented in the subtype 2 period data is a server by first checking the goal type in the service class period section. If the goal type is 0, indicating a system or server service class, you next check whether there are any server data entries. If there are entries, then the service class period is a server, and the server data describes the service classes being served by this server.

If the goal type is 0, and there are no server entries, then the service class is a system service class.
