The properties file

The properties file DFHMAMPF contains a record for every adapter service that is deployed in the runtime environment. The record contains the request name and the properties of the adapter service, as well as definitions for each server adapter.

When you deploy a new adapter service, the properties file is updated to include all of the information necessary to perform request processing for that adapter service. Each adapter service record begins with a type R record that describes the request. It can include information such as:

The type R record is followed by definitions for the server adapters that are used in the adapter service. The only server adapter that is not required in the properties file is the Web services server adapter.

The properties file is read by the DPL stub program, the navigation manager and server adapters during the processing of a request message.

To avoid problems at run time, it is important to ensure that you update the properties file correctly. By default, the properties file is updated in safe mode during the deployment process. This ensures that you do not overwrite any existing adapter service records if there is a naming conflict. If you want to update an existing adapter service record in the properties file, you should follow the deployment steps and update the properties file by setting the MODE parameter to overwrite the definitions.
