Attaches an existing state service database to the farm.

Mount-SPStateServiceDatabase [-Name] <String> [-AssignmentCollection <SPAssignmentCollection>] [-DatabaseCredentials <PSCredential>] [-DatabaseServer <String>] [-ServiceApplication <SPStateServiceApplicationPipeBind>] [-Weight <Nullable>]


Parameter Required Type Description




Specifies the database name that is created in the SQL Server database.




Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.


When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.




Specifies the database credentials for SQL Authentication used to access the state service database. If this parameter is not specified, Windows authentication is used.

The type must be a valid PSCredential object.




Specifies the name of the host server for the state service database.

The type must be a valid SQL Server host name; for example, SQLServerHost1.




Specifies the state service application to which to add the state database.

The type must be a valid name of a state service application (for example, StateServiceApp1); a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; or an instance of a valid SPStateServiceApplication object.




Specifies the weight for the state database used to load balance the allocation of new data. The default value is 1.

The type must be a valid integer in the range of 1 to 10.

Detailed Description

The Mount-SPStateServiceDatabase cmdlet attaches an existing state service database to the farm. If the session state database schema is not installed in the state service database, use the Initialize-SPStateServiceDatabase cmdlet to install the schema after the state service database has been mounted.

Input Types

Return Types

--------------EXAMPLE 1-----------------

Mount-SPStateServiceDatabase –Name “statedata1” –DatabaseServer “localhost”

This example associates a SharePoint Server 2013 farm with a SQL Server database.

This example is used in least privilege scenarios when an administrator cannot create databases in SQL. The database must already exist and be empty. The database cannot be used until the Initialize-SPStateServiceDatabase cmdlet is run, so errors could occur with this example.

--------------EXAMPLE 2-----------------

Mount-SPStateServiceDatabase –Name “statedata1” –DatabaseServer “localhost” –ServiceApplication “ServiceApp1” –Weight 10 | Initialize-SPStateServiceDatabase

This example associates a SharePoint Server 2013 farm with a SQL Server database, at the same time that it also associates the database with a service application and gives a weight of 10. The result is immediately piped to the Initialize-SPStateServiceDatabase cmdlet so that the database can be used.
