New Features for Creating and Configuring Service Providers and Service Consumers

 

The following are new features in the Web services runtime, configuration and monitoring.

      Web Services Runtime

Support for Web Services Reliable Messaging (WS-RM) is introduced.

Using WS-RM ensures that message exchange between a service provider and a service consumer is completedwithout errors. Serviceswith asynchronous operations can be consumed from an Enhancement Package or from an installed Enterprise Services Repository (SAP NetWeaver Composition Environment 7.1 / SAP NetWeaver 7.1).

      Configuring Web Services and Web Service Clients in the SOA Manager

The SOA Manager is an ABAP-based tool which provides a central location to configure Web services and Web services clients. The organization of the SOA Management cockpit into Technical Configuration and Business Administration centers is in accordance with the roles of the Technical Administrator and Business Administrator relevant for managing the SOA landscape.

A new approach to configuring Web services, called mass configuration, is available. Through mass configuration you can configure several Web services at one go.

      Monitoring Web Services  in the SOA Manager

WS-RM Messages are combined into sequences. The reliability of sequence transmission is guaranteed with the help of the Web service runtime. Using analysis tools, such as the Sequence Monitor, you can find and remove any errors that occur during transmission.

In the SOA Manager, you can also find and view the logs and traces of calls made to Web services and from Web service clients. Each call to a Web service or form a Web service client may contain trace and/or log records of different severity and status.

      Publication of Services     

A Services Registry contains entries for all services and service definitions in a landscape. From an ABAP Backend, which is based on SAP NetWeaver 7.0 SPS14, you can publish services in this registry.
