Course Overview
Develop the skills to measure, analyze, and tune common performance issues on IBM Power Systems running AIX.
Learn about performance management concepts and techniques and how to use the basic AIX tools to monitor, analyze, and tune an AIX system. The course covers how virtualization technologies such as the PowerVM environment and workload partitions affect AIX performance management. Monitoring and analyzing tools discussed in this course include vmstat, iostat, sar, tprof, svmon, netstat, lvmstat, and topas. Tuning tools include sched, vmo, ioo, no, and nfso.
The course also covers how to use Performance Problem Reporting (PerfPMR) to capture a variety of performance data for later analysis.
Each lecture is reinforced with extensive hands-on lab exercises, which provide practical experience.
The materials include AIX 7.1 enhancements, and the exercises are executed in a POWER8 lab environment.
