Message Logging/Tracing

The logging service is controlled through two system properties. These two properties are: (Detail) Levels, and Categories.

The first system property (Levels) enables the logging of messages based on defined (detail) Levels. Each level is an integer value that represents one or more types of messages to be logged. The second system property (Categories) enables logging all debug messages related to one or more function areas (categories) that you specify in a comma-separated parameter on WAS 4.0, or WAS 5.
