Advanced Crash Dump Analysis

Format: Formation en classe avec formateur
Autres formats:
 
 

The Advanced Crash Dump Analysis course provides students with essential skills to accomplish more detailed crash dump analysis than getting a stack trace and matching it to bugs. This course teaches students what information to review to determine the cause of a panic, what causes bad traps to occur, and if there is corrupt data or a hardware issue. The course also presents information on analyzing user-forced crashes and live crash dumps. The latter part of the course includes information about the SPARC architecture and assembly language and explains how this information can be used to gather additional information from crash dumps.

Students who can benefit from this course:
  • System Administrators who have some crash dump analysis experience and need more detailed information.
