F.4 Troubleshooting Configuration Assistants
To troubleshoot an installation error that occurs when a configuration assistant is running:
Review the installation log files listed in the “Reviewing the Log of an Installation Session” section.
Review the specific configuration assistant log file located in the ORACLE_BASE\ORACLE_HOME\cfgtoollogs directory. Try to fix the issue that caused the error.
If you see the Fatal Error. Reinstall message, look for the cause of the problem by reviewing the log files. Refer to the “Fatal Errors” section for further instructions.
During an installation, Oracle Universal Installer records all of the actions that it performs in a log file. If you encounter problems during the installation, review the log file for information about possible causes of the problem.
Log files are located in the SYSTEM_DRIVE:\Program Files\Oracle\Inventory\logs directory. Log filenames take the form installActionsdate_time.log (for example, installActions2003-05-14_09-00-56-am.log).
