Duration: 5 Days

In this course, you will learn 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. You will spend half of class in hands-on labs.

What You Will Learn

  • Methodology for investigating performance issues
  • Tools used to monitor HP-UX performance
  • Bottlenecks and potential problems
  • Appropriate remedial actions to take
  • Effectively utilize the range of performance tools that are available to you
  • Regularly monitor your systems and quickly recognize problems
  • Optimize your systems by identifying and removing performance bottlenecks
  • Effectively allocate resources, such as CPU, memory, disk I/O bandwidth among your critical and lower priority users and applications
  • Deliver a guaranteed level of application performance to your end users
