The Sun Systems Fault Analysis Workshop teaches system administrators and field engineers how to analyze faults, perform diagnostics analysis, and use Sun's Predictive Self-Healing technology and DTrace toolkit for the SPARC-based and x86-based Solaris computing environments. These skills directly translate to higher availability levels and increased uptime of the Solaris Operating System (Solaris OS). The course provides instruction in the use of a fault analysis method, platform-based diagnostic tools, and the fault isolation capabilities of the Service Management Facility and Fault Management Architecture as well as providing hands-on fault isolation practice in the workshop. Students who can benefit from this course:System Administrators, System Maintainers, and Field EngineersThis course counts towards the Hands-on course requirement for the Oracle Solaris 10 System Administrator Certification. Only instructor-led inclass or instructor-led online formats of this course will meet the Certification Hands-on Requirement. Self Study CD-Rom and Knowledge Center courses DO NOT meet the Hands-on Requirement.
