About this Course

This course will help you better understand the techniques of performance analysis and capacity planning on Power Systems and LPARS with IBM i. You will also develop an appreciation of how IBM i operates and interfaces with applications. You will build skills to better manage performance and capacity on Power Systems and LPARS. This course explains IBM i concepts, including the Technology Independent Machine Interface (TIMI), main storage pools, auxiliary storage pools, management of jobs, threads, tasks, job run-time structure, performance monitoring, data collection, and analysis of performance data. This course includes hands-on activities using performance data from Power Systems with IBM i to help you appreciate the concepts discussed.

While this course includes IBM i V7R1 content, it is suitable for those currently using prior versions of IBM i. First, we will focus on teaching the performance management process, the performance considerations of key hardware components and virtualization options, and tuning options to help optimize performance. During these lectures, you will gain an appreciation of the unique storage management and work management components in the IBM i architecture, and how these components need to be managed for optimal performance. Then, the class will focus on the tools and techniques to monitor, analyze, and plan for performance. The primary analysis tool that will be used is the Performance Data Investigator (PDI) which is included with IBM Navigator for i. PDI is also used with IBM Systems Workload Estimator (WLE) for capacity planning activities.
