Solaris Core Analysis, Part 1: mdb

When the kernel encounters behavior that is uncorrectable and will cause irreparable harm to the running system or, even worse, corrupt data, the system will voluntarily tap out using the panic system call to get the system down quickly, hopefully leaving a core dump in its wake for post-mortem analysis.In this blog entry we'll discuss core dumps and panic's in general. In part 2 we'll discuss a tool to make life just a little easier, the Solaris Crash Analysis Tool, or "Solaris CAT".

NAME
adb - general-purpose debugger SYNOPSIS
adb [-kw] [-I dir] [-P prompt] [-V mode] [ object [ core]] DESCRIPTION
The adb utility is an interactive, general-purpose debugger. It can be used to examine files and provides a controlled environment for the execution of programs. The adb utility is now implemented as a link to the mdb(1) utility in Solaris 9. mdb(1) is a low-level debugging utility that can be used to examine user processes as well as the live operating system or operating system crash dumps. The new mdb(1) utility provides complete backwards compatibility with the existing syntax and features of adb, including support for processing adb macro files. The Solaris Modular Debugger Guide and mdb(1) man page describes the features of mdb, including its adb compatibility mode. This mode will be activated by default when the adb link is executed.
