Use this task to browse or change the properties of Java logging.
Why and when to perform this task
Before applications can log diagnostic information, you need to specify how you want the server to handle log output, and what level of logging you require. Using the administrative console, you can enable or disable a particular log, specify where log files are stored and how many log files are kept, specify the level of detail in a log, and specify a format for log output. You can also set a log level for each logger.
You can change the log configuration statically or dynamically. Static configuration changes affect applications when you start or restart the application server. Dynamic (or run-time) configuration changes apply immediately.
When a log is created, the level value for that log is set from the configuration data. If no configuration data is available for a particular log name, the level for that log is obtained from the parent of the log. If no configuration data exists for the parent log, the parent of that log is checked, and so on up the tree, until a log with a non-null Level value is found. When you change the level of a log, the change is propagated to the children of the log, which recursively propagate the change to their children, as necessary.
To configure loggers and log handlers for use by Java logging, use the administrative console to complete the following steps:
