Microsoft.SqlServer.Management.Dmf 命名空间

The Microsoft.SqlServer.Management.Dmf namespace contains classes that represent the SQL Server policy-based management objects. 

The top-level instance is the PolicyStore class, which proves the connection to the instance of SQL Server. The other : Policy, Condition, PolicyGroupSubscription, PolicyCategory, Facets.

The DMF objects can be used to create and manage policies that control the behavior and configuration of an instance of SQL Server. All behavior and configurations are represented by facets. The Microsoft.SqlServer.Management.Facets namespace contains the objects that represent the repository of facets used when defining policies. Policies are used when defining a DAC package using the DAC objects. This enables you control policies when installing a database application structure stored in the DAC package onto an instance of SQL Server. The specified policies determine the instances of SQL Server in the SQL Fabric to which the DAC package can be deployed.

A policy is the result of applying a condition to one of more target object. The condition is a facet combined with a state of behavior, for example, Database Mail is the facet and whether it is installed or not is the state. So, specifying that Database Mail must be installed is a condition. You can create a target set of objects by applying a filter. Then, apply the condition to the target object set to make a policy.

The Microsoft.SqlServer.Management.Dmf namespace resides in the Microsoft.SqlServer.Dmf.dll file. Additionally, some supporting objects are in the Microsoft.SqlServer.DmfSqlClrWrapper.dll and Microsoft.SqlServer.Dmf.Adapters.dll files. You will have to import these files to access the classes in the Microsoft.SqlServer.Management.Dmf namespace.

By using the Microsoft.SqlServer.Management.Dmf namespace, you can do the following:

• Create, read, update and delete policies, target objects, conditions, filters and subscriptions.

• Script out the DMF objects associated with the connection.

• Define a target object set by using a filter.

• Extract the existing configuration state from an instance of SQL Server and create a policy.

• Export and import DMF objects.

• Assign a policy to a set of target objects.

• Evaluate a policy.

• Have target subscribe to policy.
