Troubleshooting

This section provides some troubleshooting tips for problems that are revealed by prerequisite tests. Prerequisite tests can generate warnings or failure notices. If you receive a warning, you can correct the problem immediately or after the installation or upgrade software runs. Failures must be corrected before you can continue. Most of the troubleshooting topics are for prerequisite failures.

Note: Many prerequisite tests rely on general indicators to identify problem areas. Passing a prerequisite test is not a guarantee that everything is configured properly. It is important to meet all of the server requirements, verify that supported versions of the required software are installed and complete all of the configuration tasks.

The following prerequisite tests are run:
