Introduction:
 
Gain the skills to measure, analyze, and tune AIX subsystems on IBM eServer pSeries hardware for optimum performance. Learn how to manage the performance of AIX 5L and the performance of applications running under AIX 5L. Examine performance management concepts and techniques and the use of standard AIX tools (sar, iostat, vmstat, netstat, and tuning commands such as schedo, vmo, no and ioo). Also, learn to use advanced AIX performance tools (tprof, svmon, and filemon). Learn how to run and use the Performance Problem Reporting tool (PerfPMR) to document and then analyze performance problems. In extensive hands-on lab exercises, reinforce each lecture and gain practical experience applicable to your performance management requirements.
 
Audience:
 
This is an advanced course for system administrators, system engineers, and system support individuals.
 
Prerequisites:
 
  • AIX 5L System Administration I: Implementation - AU140 and AIX 5L System Administration II: Problem Determination - AU160, or at least six months of equivalent experience
  • Ability to manage AIX physical and logical storage, manage networking configurations from an application server viewpoint, utilize additional subsystems including cron to schedule system tasks and accounting to analyze system activity, and pull together many of the topics learned in previous courses to start addressing real-life system administrator issues
 
Customize it:
 
This 5-day IBM course will be customized to your needs and specifications. Eno.com will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of IBM training. They will typically have a broad and general course, one size fits all, already developed and just put your organization?s ame on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren't too sure of what that was. We fit the class to your needs. We never fit you into our standard, one size fits all, class.
