IBM Software Group Defining SLAs through Service Policy is definition of a performance goal IBM Software Group Defining SLAs through Service Policy is definition of a performance goal used by VE to decide how to manage resources in the server environment Defined in terms of the end user result the customer wishes to achieve Comprised of three parts: A set of classification rules to decide which policy applies to a given request A performance goal the user desires to be achieved This is a response time based goal (i. e. 500 ms average response time for all requests) An importance level to inform VE of the relative priority of different classes of work 9 VE does not cause starvation but will handle different workloads with different priorities Web. Sphere © 2008 IBM Corporation 9

IBM Software Group Techniques to Meet SLAs VE two primary techniques to meet Service IBM Software Group Techniques to Meet SLAs VE two primary techniques to meet Service Policy objectives Ø Traffic Shaping and Application Placement Traffic Shaping Ø Not all requests are equal Ø Serving work first-come-first-serve is not necessarily the best approach Ø Controls Traffic in a number of ways • Prioritization – Processed in order of importance • Flow Control – Using queuing, the rate of work being sent to the server cluster is controlled • Traffic Spraying – Dynamic Workload Management • Overload Protection – Control total amount of outstanding work for each class of service Application Placement Ø The ability to adjust the size of a Dynamic Cluster in real-time Ø Controls how much capacity is online for an application at any moment in time Ø Integration with Tivoli Intelligent Orchestrator to provision additional resources into VE 10 Web.

IBM Software Group Dynamic Operations Overview Dynamic Operations enables set up, monitoring and management IBM Software Group Dynamic Operations Overview Dynamic Operations enables set up, monitoring and management for multiple applications sharing server resources. A service policy is used to specify response time goals application requests must meet. System resources are managed based on current workload, and relative importance of requests. The On-Demand Router is used to route work to application server nodes Ø Enhanced version of the Proxy Server Ø Controls request prioritization, flow, and routing in an Virtual Enterprise (VE) environment 11 Web.

IBM Software Group Health Management – Health Policies Health policies can be defined for IBM Software Group Health Management – Health Policies Health policies can be defined for common server health conditions Health conditions are monitored and corrective actions taken automatically Notify administrator Ø Capture diagnostics Ø Restart server Ø Application server restarts are done in a way that prevent outages and service policy violations 22 Web. Sphere • Health Conditions • Age-based: amount of time server has been running • Excessive requests: % of timed out requests • Excessive response time: average response time • Excessive memory: % of maximum JVM heap size • Memory leak: JVM heap size after garbage collection • Storm drain: significant drop in response time • Workload: total number of requests © 2008 IBM Corporation

IBM Software Group Custom Health Conditions VE enables customers to create expressions defining what IBM Software Group Custom Health Conditions VE enables customers to create expressions defining what “unhealthy” means in their environment Custom expressions can be built using operands which represent metrics from the On Demand Router, base PMI metrics (WAS only), MBean operations and attributes (WAS only), and/or URI return codes. Complex expressions using a mix of operands is supported. Other middleware server types can leverage the ODR metrics and URI return code operands Create the health policy by using the create. Health. Policy Admin. Task command 23 Web. Sphere © 2008 IBM Corporation

IBM Software Group Custom Health Actions Customer often have needs for specific actions to IBM Software Group Custom Health Actions Customer often have needs for specific actions to occur when an unhealthy situation is detected. VE provides flexibility to customers by allowing them to define custom actions in addition to a standard set VE provides and allow them to define an action plan to be carried out when the unhealthy situation is detected. 24 Web.

IBM Software Group Server Maintenance Mode VE provides the capability to isolate a running IBM Software Group Server Maintenance Mode VE provides the capability to isolate a running server (of any type) from production traffic. This allows for problem determination to be performed on the server or other maintenance without disruption to production traffic. If the server is a member of a dynamic cluster, a new cluster member will first be started before the server is placed into maintenance mode in order to assure the minimum policy on the dynamic cluster is met. 27 Web.
