      - Database server files
        Database server files are created in default directories, or in a directory that the relevant configuration parameter specifies. A database administrator might need to edit or examine the content of files that are used by the database server.
      - Troubleshooting errors
        Occasionally, a series of events causes the database server to return unexpected error codes.
      - Event Alarms
        The database server provides a mechanism for automatically triggering administrative actions based on an event that occurs in the database server environment. This mechanism is the event-alarm feature.
      - Messages in the database server log
        Unnumbered messages are printed in the database server message log (online.log). The error messages include corrective actions.
