In this topic I will provide information how to generate Oracle Solaris OS crash dump report using Solaris Crash Analyzer Tool.

Here I will provide information how to find out root cause of Oracle Solaris OS crash dump reboot or hung up.
If your system properly installed and configured according EIS (Enterprise Installation Standard) - then you dump
device must be configured as separated raw disk and must have size at least more than installed physical memory
on the server. In most system the dump device is the same swap device. If your system is frame based and installed memory
is more than 320GB ( SAS disk) - then you need assign to the system dedicated dump device no less thane size of physical
memory. Otherwise - in time when system will go to crash dump, the memory state will fully dumped to the dump device
and you will lose last memory snapshot to make root cause analyze of system crash.
