Solaris 11 Systems Administration Performance Management (Monitoring, Analysis, Modifications) – 3 Days

Course Description

The Solaris 11 Systems Administration: Performance Management course introduces participants to performance management principles, monitoring utilities / tools, and analysis for the Solaris 11 Operating Environment. The course includes a review of Solaris subsystems, along with the utilities provided to monitor system efficiency including sar and the *stat family of tools.  This revision also presents tools new to Solaris 11, including dtrace and kstat.  In each area of discussion, emphasis will be placed on writing tools for monitoring and analysis.  These tools will include Korn shell scripts, Perl procedures, and C language programs.  Systems: Solaris 11, SPARC or x86/x64 hardware platforms.

Prerequisites

It is assumed that the participant has successfully completed the Oracle Solaris 11 System Administration  course, or has equivalent  system time as a user, and is comfortable with basic systems administration functions.

Objectives

On completion of this course, a systems administrator should be able to:

    • Describe performance management fundamentals
    • Use the Solaris 11 OS and third-party tools to analyze performance
    • Write tools in various languages
    • Use Solaris 11 performance data extensions (kstat, dtrace)
    • View and set kernel-based tuning parameters
    • Monitor and report on process and thread activity
    • Modify CPU scheduling and virtual memory operations
