Troubleshooting Guide

Chapter 11. Diagnostic Tools for UNIX-Based Systems

Use the diagnostic tools described in this chapter to gather and process data that can help identify the cause of a problem you are having with your UNIX-based system.

Once the data is collected, it can be examined by you or by someone who is familiar with the problem, or provided to DB2 Customer Service for analysis.

The diagnostic tools available for UNIX-based systems include:

System error log (syslog)

DB2 logs error and warning conditions to the system error log (syslog). (See "Using the System Error Log (syslog)".)

Core file

A core file is created when severe errors occur. It contains a memory image of the terminated process, and can be used to determine what function caused the error. (See "Using the Core File".)

Process status utility (ps)

The ps command returns process status information about active processes to standard output. (See "Viewing Process Status Using the ps Command".)

Other UNIX-based commands

UNIX-based systems provide various tools and utilities to diagnose problems. For a summary, see "Other Commands".
