In-Depth Information
Enterprise Service Repository
Enterprise Service Repository (ESR) is a repository for the enterprise service inventory of
assets built by an organization over time. This includes tools such as Enterprise Services
Builder and Services Registry. Enterprise Services Builder helps to build enterprise services
based on enterprise SOA standards. The services are then published in the Services Registry
for enterprise-wide consumption.
System Landscape Directory (SLD)
System Landscape Directory (SLD) is a central provider of all software product and com-
ponent definitions to the ESR. New software product and component definitions are created
in SLD and are exported to the ESR to begin the development of the service interfaces.
Integration Directory
Integration Directory is the central configuration tool that helps in configuring message pro-
cessing, communication and security, and routing rules for message flow.
Configuring and Monitoring
Runtime Workbench and NetWeaver Administrator (NWA) are two tools provided by SAP
for monitoring and administering the PI solution. SAP is moving more monitoring and ad-
ministration capabilities to the NWA tool, consistent with centralizing these activities across
the entire SAP solution in a client landscape.
Integration Server
Integration Server is the runtime environment for the service interfaces and is installed as an
ABAP component. Other PI components, such as ESR, SLD, and ID, are installed as Java
applications.
Advanced Adapter Engine
This component consists of a number of adapters, such as the file adapter, IDOC adapter
and JMS adapter. Theses adapters provide built-in mediation, mapping, queuing, and other
capabilities between provider and consumer business applications. Advanced Adapter
Engine can be installed as a central adapter engine along with Integration Server, or as a
separate installation.
Enterprise Service Bus
Enterprise Service Bus (ESB) is an enterprise SOA environment combining the different
service providers and consumers on a single communication infrastructure that provides
functions such as runtime services, thereby enabling service-based communication.
