Parameters

Parameter

Required

Type

Description

Identity

Required

Microsoft.SharePoint.PowerShell.SPWebApplicationPipeBind

Specifies the URL or name of the Web application to delete.

The type must be a valid URL, in the form http://server_name, or a valid name, in the form WebApplication-1212.

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

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.

noteNote:

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
