The Introduction to Crash Dump Analysis and the SunOS Kernel course provides students with essential skills to diagnose and resolve system problems, beginning with whether a system problem is due to hardware or software. If it's hardware, which piece of hardware is causing the problem? If it's software, is there a patch that fixes this problem? What tools can be used to help identify the causes of system problems? Where can they be obtained, and how are they used? This course helps students to answer these questions and to identify and resolve basic Solaris Operating System (Solaris OS) problems successfully.
Students who can benefit from this course
- Experienced System Administrators, Support personnel, and Driver Developers

 | Skills Gained |
| |
Distinguish software-caused system crashes from hardware-caused system crashes Retrieve initial analysis information from a crash dump using Solaris CAT, ACT, the adb debugger, and the mdb debugger Distinguish among unique panic string, bad trap, and hang crash dumps Identify appropriate SunSolve search strings for unique panic string and bad trap crash dumps
| | appropriate SunSolve search strings for unique panic string and bad trap crash dumps Use the SunSolve program to find bugs and cases related to the crash dumps or error messages Given a C structure declaration, describe how the data structure is stored in memory and how it looks when displayed by Solaris CAT, the adb debugger, and the mdb debugger Describe the major kernel subsystems and use Solaris CAT, the adb debugger, and the mdb debugger to display the subsystems' related data structures
