Examine Installation Log Files

If a problem occurs during installation or uninstallation, check the appropriate log file in the logs directory:

Solaris OS: /var/sadm/install/logsLinux: /var/opt/sun/install/logs

Examining the uninstall and installer log files (along with the Java ES configuration log and component logs) can help locate the source of problems. For example, you can compare the packages listed in the installation log to the packages listed in the uninstallation log.

Most logs have two versions:

The following table lists the formats of the log files.

To use the log files for troubleshooting, attempt to isolate the first problem that occurred. Often, the first problem leads to successive problems.

ProcedureTo Use Log Files for Troubleshooting

The log files can give you clues that determine your next steps, such as these:

  1. Review the installation summary file, which provides a high-level description of what was installed and configured.

    If a problem occurred, see what component caused the problem. If multiple problems occurred, isolate the first.

  2. Review the detailed log files.

    1. Look for the first error or warning that occurred and attempt to resolve it. Sometimes resolving one error resolves a number of seemingly unrelated errors that follow.

    2. Find the name of the component or package that caused the problem.
