23 Apr 2008 Learn how to dynamically manage service availability using
WebSphere® Service Registry and Repository V6.1 service life cycle
governance model to describe the status of a service and WebSphere ESB’s
endpoint lookup mediation primitive to query the registry for this information
and select the appropriate service endpoint dynamically at run time.
Overview
This article demonstrates how to perform dynamic service availability
management using WebSphere Enterprise Service Bus and WebSphere Service
Registry and Repository (Service Registry). We'll use Registry's service life cycle governance model to describe the status of
our service (either maintenance or production), and WebSphere ESB’s
endpoint lookup mediation primitive to query this information stored in
Service Registry and select the appropriate
service endpoint dynamically at run time.
Note: This version of the article applies specifically to Service Registry
V6.1. Another version
of the article is available for Service Registry
V6.0.2.
The article takes you through a fictitious use case that demonstrates the
steps required to dynamically manage service availability, including:
- Publishing the existing service artifacts to Service
Registry
- Developing the new composite service application in WebSphere
Integration Developer without requiring any manual coding
- Publishing the new service artifacts to Service Registry
- Deploying the new composite service application to the WebSphere ESB
run time
- Testing the deployed solution
