When you stop an application, you must pick one of the following
options:
When work completes: Specifies that WebLogic Server wait for the
application to finish its work and for all currently connected users to
disconnect.
Force stop now: Specifies that WebLogic Server stop
the application immediately, regardless of the work that is being
performed and the users that are connected.
Stop, but continue servicing administrative
requests: Specifies that WebLogic Server stop the application
once all its work has finished, but to then put the application in
Admnistrative Mode so it can be accessed for administrative
purposes.
