SharePoint 2013

Applies to: SharePoint Server 2013 Enterprise

Topic Last Modified: 2015-03-09

Removes the association to a state service database from the farm without dropping the database in the Microsoft SQL Server database.

Dismount-SPStateServiceDatabase [-Identity] <SPStateDatabasePipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]]

The Dismount-SPStateServiceDatabase cmdlet removes a state service database from a service application and deletes the associated SharePoint object. This cmdlet does not delete or alter the state service database.

SharePoint Management Shell


Parameter Required Type Description




Specifies the state service database to remove from the service application.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid name of a state database (for example, StateSvcDB1); or an instance of a valid SPStateServiceDatabase object.




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.




Prompts you for confirmation before executing the command. For more information, type the following command: get-help about_commonparameters




Displays a message that describes the effect of the command instead of executing the command. For more information, type the following command: get-help about_commonparameters

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

Dismount-SPStateServiceDatabase -Identity 9703f7e2-9521-47c3-bd92-80e3eeba391b

This example removes the association between the SharePoint farm and the SQL Server database without dropping the SQL Server database.

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

Get-SPStateServiceDatabase -ServiceApplication F9168C5E-CEB2-4faa-B6BF-329BF39FA1E4 | Dismount-SPStateServiceDatabase

This example dismounts a single database because only the Identity parameter is used.
