Defining most debug scopes and attributes is dynamic and can be used to enable debugging while the server is running. However, setting some scopes or attributes requires a restart to take effect.
To define the debug settings for a server instance:
The Settings for ServerName page is displayed.
Note: If you create applications to run on WebLogic
Server, you can configure your applications to generate messages of
DEBUG. These messages are never forwarded
to the domain log and are intended to contain detailed information
about the operation of an application or the server. For more
information, see Specify
severity level for Loggers.
Not all changes take effect immediately — some require a restart. For more information, see Use the Change Center.
