Table OV_PM_CategoryOnNode

The OV_PM_CategoryOnNode table represents the policy categories that are deployed on a managed node. However, it is not used to expose a category inventory to PMAD clients. The main purpose of this table is to store the category CheckSum (a directory timestamp) that is calculated during instrumentation deployment. This feature is used by PMAD to support the automatic instrumentation redeployment. Records in this table are cascaded, and so removed automatically when the corresponding category or managed node is removed.

Column Name	Constraint	Column Type	Description
CategoryName	PK, FK1, I1	nvarchar(32)	Name of the category.
NodeId	PK, FK2, I1	nvarchar(64)	ID of the node.
CheckSum		datetime	Timestamp of the instrumentation directory (with the same name as the referenced category) at the time the policy was deployed to the node.
