You specify the application service names that an AppServer supports when you configure an AppServer instance. Client applications use the application service names you specify to identify to a NameServer an AppServer instance with which to connect. The NameServer then chooses a particular AppServer instance to connect based on whether it supports the application service specified by the client.
For multiple AppServer instances that support the same application service name, you typically configure all such AppServer instances with functionally identical capabilities. Most important among these common capabilities include using the same ABL procedure installation and configuration, and assigning the same operating mode to each AppServer instance.
