You are assisting on Oracle Java Cloud Service (JCS) customer who has reported slow response times in their production system. The customer has provided you with details of the number of concurrent users, the number and size of application requests, their data volumes, and their desired CPU utilization. You have only a limited time window during which you can change the production environment.
What is the optimal order of priority for your initial remedial actions?

• A.1. Use Oracle Fusion Middleware Control to configure a dashboard with custom metrics2. Use Java Mission Control to monitor JVM heap usage3. Take Java Threads dumps and search for locked threads
• B.1. Configure an identically sized JCS environment in an alternate data center2. Deploy the customer application to the new environment3. Implement the Oracle JCS tuning methodology to compare the results
• C.1. Log in to the JCS virtual hosts and use Linux command line tools to monitor performance2. Change the Linux kernel parameters to improve performance3. Apply patches to the OS and the WebLogic Server
• D.1. Use the WebLogic Diagnostic Framework to gather performance metrics2. Tune the WebLogic environment based on diagnostic results3. Monitor application performance in JCS Control Console and Fusion Middleware Control console
• E.1. Monitor system metrics such as utilization of disc/CPU, network data transfers, persistent store writers, and logging volume2. Locate or identify bottlenecks in the application, database, and WebLogic configuration3. Analyze the results, suggest changes that are likely to give the maximum benefit, and then prioritize configuration changes based on the analysis.
