Appendix I. Important log files

Log files provide information about software components in the environment as

they initialize and run. The logs usually cause low-to-medium performance

impact and can be useful to review after an error or problem condition occurs.

Analyzing logs is a significant step in the problem determination process.

Generally, logs are always enabled. The level of most logging can be modified to

enable more detailed logging messages, but be aware that this change could

have a big impact on performance and should be changed back to normal

logging level after the problem is resolved.

This appendix provides the following information on log files:

 Default location of log files

 How to change their location for systems management purposes

 Log file properties for all the software related to WebSphere Commerce, such

as typical log entry formats, types of logs, when and how to use them, where

is their default location, and how to change their properties

 Where to find more information

Tip: The log files are extremely important and useful for troubleshooting, and

should be checked frequently. For systems management purposes, you can

move all log files into a common directory tree by changing the location of the

log files. Make sure that the directories for the log files are already created.

You will get application failures when the log files cannot be created.
