Microsoft.SqlServer.Management.Smo.Wmi Namespace

The Microsoft.SqlServer.Management.Smo.Wmi namespace contains classes that provide programmatic access to the Windows Management Instrumentation (WMI) from an SMO application.

The Microsoft.SqlServer.Management.Smo.Wmi namespace contains all the classes that represent the SQL Server WMI. The classes in this namespace do not require a connection to an instance of SQL Server. The classes in this namespace control the SQL Server service and the SQL Server Agent service as represented by the Server class and the JobServer class. WMI is hierarchically above the SMO Server class. The WMI classes are also used to set the network protocols and libraries for client and server installations of SQL Server.

The Microsoft.SqlServer.Management.Smo.Wmi namespace resides in the Microsoft.SqlServer.Smo.dll assembly file. Also, some of the enumeration classes are in the Microsoft.SqlServer.WmiEnum.dll assembly file. You will have to import both files to access the classes in the Microsoft.SqlServer.Management.Smo.Wmi namespace.

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

  • Stop, start, and pause both the instance of SQL Server and SQL Server Agent.

  • Set protocols, network libraries, and IP address information for SQL Server services and clients.

  • Manage SQL Server aliases.

NoteNote

In SQL Server 2008, you must register the Microsoft.SqlServer.SqlWmiManagment.dll by using regasm.exe before you can use the Microsoft.SqlServer.Management.Smo.Wmi classes.
