8.6: Diagnosing configuration and installation problems

WebSphere Application Server uses a database to store and share configuration information across nodes. Problems configuring the database are described in the installation problems section.

Generally, if the database is not configured properly, the WebSphere Application Server installation process will fail. Configuration problems occur after the product is installed.
