Overview

Normally, an application monitor can be removed from a node by unassigning it from the "Manage Assigned Application Monitors" page. If this page is not bringing up the application, or if the node is does not have any SAM related checkboxes in it's "List Resources" page, you may need to delete the entries directly from the Orion database manager.
