Operational policy
With WebSphere XD, you can differentiate application service levels according to your business requirements. The goals-directed infrastructure capabilities of WebSphere XD mean that user requests are classified, prioritized, queued, and routed to servers based on application operational policies that are tied to business goals. Application performance is optimized according to these policies that reflect service level goals and relative importance to the organization.
Simply put, you can state what applications are important to you, and these applications will get the highest priority access to your WebSphere resources at the right time. This can help you ensure, for example, that your business-critical transactions get the best quality of service.
WebSphere XD offers two types of operational policies:
Service policy Service policies definitions are made up of two key items, namely goals and importance. The goal portion of the service policy defines how incoming work is evaluated and managed in order to ensure and detect if work is meeting its assigned service policy levels. The importance is used in times of resource contention in order to identify the most important work in the system, and give it the priority.
Health policy WebSphere XD provides a health monitoring and management subsystem. This subsystem continuously monitors the operation of servers to detect functional degradation that is related to user application malfunctions. The health management subsystem consists of two main elements, namely health policies and the health controller.
WebSphere XD supports the following health policies:
Age-based condition: Monitors for servers that have been running longer than a configured time period.
