DoE StepsDoE Steps


Methodology Start with Domain Level: Transient Processes Then proceed for Domain Level: Durable Processes Do not tinker with Oracle prohibited, deprecated, OC4J, Database,

JVM specific and properties which have miniscule effect on performance.

Assumptions OC4J is already tuned Dehydration database is already tuned JVM is already tuned Hardware and Networking assets are already identified and tuned Process to be tuned is already identified and optimized at code

level.

Methodology & AssumptionsMethodology & Assumptions


Assumptions Domain Level

• processCheckSecs = -1• statsLastN = 0• validateXML = false• auditLevel =production• slowPerfThreshold = 2 sec (for durable processes only)• workerQueueConnectionPoolMinSize = worker threads (for durable processes

only)• dspMaxRequestDepth = 600 (for durable processes only)• idempotentThreshold = 30 sec (for durable processes only)• minBPELWait = 2 sec (for durable processes only)

Process Level• completionPersistLevel = instanceHeader • inMemoryOptimization = true• completionPersistPolicy = faulted• idempotent =true• nonBlockingInvoke = true (pay attention to: connection pool size >=

(InvokerBean listener threads + WorkerBean listener threads + maximum concurrent request-response invocations)
