How it works...
The Preferences section changes will enable some messages in the Administration Console
that will warn the user when the edit lock is already being used in another browser session.
This is important in a production environment to avoid the changes being made by other
administrators at the same time.
The WLST Script Recording changes will enable a Jython script to be recorded to every change
made in the Administration Console. The script is recorded by default in the $DOMAIN_HOME
root directory with a filename Script*.py .
With the backup configuration enabled, every time the domain configuration is modified,
a JAR file containing the old coniguration ($DOMAIN_HOME/config/* ) will be archived until
the limit of 250 archives as you defined in Archive Configuration Count. Change the value
so it suits your needs. JAR will be saved in the directory $DOMAIN_HOME/configArchive/
config-XXX.jar . The lesser the XXX number, the older the configuration archive is.
