The following article "Automatically deactivating service level agreements in WebSphere Service Registry and Repository" was published on developerWork by one of our architects Martin Smithson.
Service Level Agreements (SLAs) in WebSphere Service Registry and Repository (WSRR) are agreements between service providers and consumers that can be enforced by ESBs at runtime when processing requests to ensure that the service consumer is authorised to invoke the target service. You can specify the dates between which an SLA is active, but WSRR does not automatically monitor SLAs in order to deactivate those SLAs whose termination dates have passed. This article shows you how to use a scheduled task in WSRR to monitor SLAs and automatically deactivate those that have expired.
It went live on the WebSphere zone, not the WSRR zone, which is why I haven't spotted it yet!
