hP-uX performance and tuning

By attending HP-UX Performance and tuning workshop, Participants will learn to:

  • Explore a methodology for investigating performance issues
  • Identify tools used to monitor HP-UX performance
  • Identify bottlenecks and potential problems
  • Determine appropriate remedial actions to take

The HP-UX performance and tuning training course shows you how to optimize the performance of your computing environment, including multiprocessor and cell-based systems. Extensive hands-on labs allow you to gain experience using standard UNIX and HP-specific tools to monitor, analyze, and tune the performance of HP-UX systems and common network services.

Attend the following courses or possess equivalent knowledge:

  • HP-UX System and Network Administration
  • HP-UX Operating System

  • Experienced HP-UX system and network administrators
