AIX Training Overview
This course is designed to teach performance concepts relating to Unix
systems (IBM AIX pSeries and RS/6000 hardware platforms), and to use
these concepts to develop a tuning methodology to monitor, interpret, and adjust mechanisms that affect performance. The course will Develop the skills to measure, analyze, and tune AIX subsystems for optimum performance. The course will also show how to use standard AIX performance tools (sar, iostat, vmstat, and trace), along with advanced AIX performance tools (tprof, svmon,filemon, monitor, and nmon).
AIX Training Prerequisites
It is assumed that the student has experience with interactive Unix
systems with user-level commands, basic shell or PERL scripting
techniques, and essential systems administrator functions.
AIX Training Course duration
This course requires four (4) days, approximately 70 % lecture,
and 30 % lab time.
AIX Training Course Objectives
Upon completion of this course, a system performance analyst will be
able to : understand fundamental performance concepts for memory
management, CPU management, and I/O management in AIX systems;
use supplied monitoring tools to interpret performance statistics.
