    Explanation/Reference:

    Section: Database Architecture & Resource Management, RAC, ASM

    http://download.oracle.com/docs/cd/B28359_01/server.111/b28310/diag001.htm

    The V$DIAG_INFO view lists all important ADR locationsfor the current Oracle Database instance.

    The following table describes some of the information displayed by this view.

    The alert log is an XML file that is a chronological log of database messages and errors. It is storedin the ADR

    and includes messages about the following:

    - Critical errors (incidents)

    - Administrative operations, such as starting upor shutting down the database, recovering

    the database, creating or dropping a tablespace, and others.

    - Errors during automatic refresh of a materialized view

    - Other database events

    You can view the alert log in text format (with the XML tags stripped) with Enterprise Manager and with the

    ADRCI utility. There is also a text-formatted version of the alert log stored in the ADR for backward

    compatibility. However, Oracle recommends that any parsing of the alert log contents be done with the XML-formatted version, because the text format is unstructured and may change from release to release.

    In 11g the default alert log is now in xml format, text is provided for backward compatibility.
