Using the Progress AppServer
AppServer Startup and Shutdown
You typically configure AppServer instances and NameServers to start up at system startup time. The Progress Explorer framework provides a graphical user interface and an equivalent set of command-line utilities that you can use to configure, startup, and manage NameServers and AppServer instances. For more information, see Administration."
Progress Startup Parameters
You can also configure the Application Broker to pass a set of Progress startup parameters to any Application Server processes that it starts. These startup parameters have the same effect on each Application Server process as the startup parameters used to start a Progress 4GL client. For example, one of the startup parameters you specify might be the Database (-db) parameter to indicate that all Application Server processes in the pool are to connect to a specific database when they start up.
AppServer Registration
When you start an AppServer instance, the first thing the Application Broker does is to register with the controlling NameServer that you specified during AppServer configuration. When you shut down an AppServer instance, the Application Broker immediately unregisters the AppServer with the controlling NameServer, ensuring that the NameServer no longer makes this AppServer available for client connection requests.
