Oracle Net8 Configuration and Troubleshooting

Looking at Net8 Log Files

All of the various Net8 facilities generate log files, or have the ability to generate log files, while they are running. These log files can provide you with all sorts of useful information. At a minimum, you can tell when a facility such as a listener has been started and stopped.

You can also change the log filenames to something other than their defaults, if that’s what you prefer. Table 10.2 lists the default log filenames that are used, and provides a brief description of each log file’s contents.
