Troubleshooting Guide
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 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, for more information.
- 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, for more information.
- Other UNIX-based commands
- UNIX-based systems provide various tools and utilities to diagnose
problems. For a summary, see Other Commands.
