Using Oracle Diagnostic Logging

Oracle HTTP Server Administrator’s Guide

Oracle offers a new method for reporting diagnostic messages. This new method,
Oracle Diagnostic Logging (ODL), presents a common format for diagnostic
messages and log files, and a mechanism for correlating all diagnostic messages
from various components across Oracle Database. Using ODL, each component logs
messages to its own private local repository. A tool called LogLoader collects
messages from each repository and loads them into a common repository where
messages can be viewed as a single log stream, or analyzed in different ways.

You can view Oracle Database diagnostic log files using a text editor.

Oracle HTTP Server enables you to choose the format in which you want to
generate log messages. You can either continue to generate log messages in the
legacy Apache message format, or generate log messages using ODL, which
complies with the new Oracle-wide standards for generating log messages.

To enable Oracle HTTP Server to use ODL, enter the directives specified in the
subsequent section in the

 file. Oracle recommends that you enter the

directives before any modules are loaded (LoadModule directive) in the
httpd.conf

 file so that module-specific logging severities are in effect before

modules have the opportunity to perform any logging.

Enables you to switch between ODL and legacy Apache logging facility.
