The old instances may raise exceptions before they can gracefully shut down because the schema no longer matches what the old application's EOF expects. *Try it out on a test server first and then update this page so everyone knows\!*

101 -You can do most of the standard tasks you do in Monitor by calling direct actions. They are in a different query handler, _/admin_. They follow the same format and use the same query parameters. Those DA can be useful if you need to restart instances or other tasks within ant or other build/deployment systems.

105 -_?type=ins&name=AppName-InstanceNo_ : return details about one specific instance
104 +You can do most of the standard management tasks you'd normally do in JavaMonitor's web UI by calling standard WebObjects Direct Actions. Instead of using the ##/wa/## request handler though, these management tasks use a new ##/admin/## request handler. These Direct Actions can be very useful, especially if you need to restart instances or other do tasks from the command line, from within Ant or other build or deployment systems.

106 +List of available direct actions :
107 +
108 +* **##info##** : returns the details (number of deaths, state, etc.; see example above), in JavaScript Object Notation (JSON)
109 +** **##?type=all##** : Returns details about all instances of all applications
110 +** **##?type=app&name=##**{{color value="blue"}}{{AppName}}{{/color}} : Returns details about all instances of a specific application
111 +** **##?type=ins&name={{color value="blue"}}{{AppName}}{{/color}}-{{color value="blue"}}{{InstanceNumber}}{{/color}}##** : Returns details about one specific instance
112 +* **##running##** : Returns **##YES##** or **##NO##**
113 +* **##stopped##** : return NO if the instance is running, YES if not.
114 +* **##bounce##** : more on it later.
115 +* **##clearDeaths##** : clear the number of deaths (same action as clicking the "Clear deaths" in JavaMonitor)
116 +* **##turnScheduledOn##** : turn scheduling on for an application or instance. Call ///turnScheduledOff// to do the opposite.
117 +* **##turnRefuseNewSessionsOn##** : turn "Refuse new sessions" on, call //turnRefuseNewSessionsOff// to do the opposite.
118 +* **##turnAutoRecoverOn##** : guess what? It activate "Auto recover" And guess again? ///turnAutoRecoverOff// do the opposite
119 +* **##forceQuit##** : force quit an application, might be useful to call it from a monitoring system.
120 +* **##stop##** : stop an application/instance the normal way.
121 +* **##start##** : start an application/instance the normal way.
