Performance Tuning for Linux - ZL20G

Performance Tuning for Linux - ZL20G


This course targets experienced Linux and z/VM system administrators and other IT professionals who are responsible for the performance and tuning of mainframe systems.


Prerequisites for this course are:


4 days.

Course Objectives

This course is designed to teach in-depth performance methodologies for Linux and z/VM systems needed to prevent and eliminate system bottlenecks. In addition, this class covers tuning strategies that help to increase system efficiency, and describes monitoring techniques used to analyze server performance. The information provided during this course applies to running enterprise Linux distributions on z/VM. The course includes lab exercises to reinforce what students learn during class.

At the end of this course, students should be able to:

  • Define IBM System z virtualization and server consolidation concepts
  • Identify performance bottlenecks at the hardware, operating system, and application levels
  • Eliminate memory, disk, processor and network bottlenecks
  • Describe tuning concepts and tasks
  • Use tuning tools to analyze and optimize z/VM and Linux performance
  • Define memory configuration for large applications (for example JVM and Oracle/DB2)
