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\!*

102 -==== Direct Actions for Management Tasks ====
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.
103 103  
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.
