DESCRIPTION

The New-CimInstance cmdlet creates an instance of a CIM class based on the class definition on either the local computer or a remote computer.



Use the Property parameter to set the initial values of the selected properties.



By default, the New-CimInstance cmdlet creates an instance on the local computer.





PARAMETERS

-CimClass <CimClass>

Specifies a CIM class object that represents the type of the instance.



You can use the Get-CimClass cmdlet to retrieve the class declaration from a computer.



Using this parameter results in better client side schema validations.



Required? true

Position? 1

Default value none

Accept pipeline input? True (ByValue)

Accept wildcard characters? false



-CimSession <CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession

or Get-CimSession cmdlet. The default is the current session on the local computer.



Required? true

Position? named

Default value none

Accept pipeline input? True (ByValue)

Accept wildcard characters? false



-ClassName <String>

Specifies the name of the CIM class of which the operation creates an instance.



Note: You can use tab completion to browse the list of classes, because Windows PowerShell gets a list of classes from the local WMI server to

provide a list of class names.



Required? true

Position? 1

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-ClientOnly [<SwitchParameter>]

Indicates that the instance is only created in Windows PowerShell???? without going to the CIM server. You can use this parameter to create an

in-memory CIM instance for use in subsequent Windows PowerShell operations.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-ComputerName [<String[]>]

Specifies the name of the computer on which you want to run the CIM operation. You can specify a fully qualified domain name (FQDN), a NetBIOS

name, or an IP address.



If you specify this parameter, the cmdlet creates a temporary session to the specified computer using the Ws-Man protocol.



If you do not specify this parameter, the cmdlet performs the operation on the local computer using Component Object Model (COM).



If multiple operations are being performed on the same computer, connecting using a CIM session gives better performance.



Required? false

Position? named

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-Key [<String[]>]

Specifies the properties that are used as keys. CimSession and ComputerName cannot be used when Key is specified.



Required? false

Position? named

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-Namespace [<String>]

Specifies the namespace of the class for the new instance.



The default namespace is root/cimv2.



Note: You can use tab completion to browse the list of namespaces, because Windows PowerShell gets a list of namespaces from the local WMI

server to provide the list of namespaces.



Required? false

Position? named

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-OperationTimeoutSec [<UInt32>]

Specifies the amount of time that the cmdlet waits for a response from the CIM server.



By default, the value of this parameter is 0, which means that the cmdlet uses the default timeout value for the server.



If the OperationTimeoutSec parameter is set to a value less than the robust connection retry timeout of 3 minutes, network failures that last

more than the value of the OperationTimeoutSec parameter are not recoverable, because the operation on the server times out before the client

can reconnect.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-Property [<IDictionary>]

Specifies the properties of the CIM instance using a hash table (name-value pairs).



If you specify the CimClass parameter, then the New-CimInstance cmdlet performs a property validation on the client to make sure that the

properties specified are consistent with the class declaration on the server. If the CimClass parameter is not specified, then the property

validation is done on the server.



Required? false

Position? 2

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-ResourceUri <Uri>

Specifies the resource uniform resource identifier (URI) of the resource class or instance. The URI is used to identify a specific type of

resource, such as disks or processes, on a computer.



A URI consists of a prefix and a path to a resource. For example:



http://schemas.microsoft.com/wbem/wsman ... ogicalDisk

http://intel.com/wbem/wscim/1/amt-schem ... alSettings





By default, if you do not specify this parameter, the DMTF standard resource URI http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/ is used

and the class name is appended to it.



ResourceURI can only be used with CIM sessions created using the WSMan protocol, or when specifying the ComputerName parameter, which creates

a CIM session using WSMan. If you specify this parameter without specifying the ComputerName parameter, or if you specify a CIM session

created using DCOM protocol, you will get an error, because the DCOM protocol does not support the ResourceURI parameter.



If both the ResourceURI parameter and the Filter parameter are specified, the Filter parameter is ignored.



Required? true

Position? named

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-Confirm [<SwitchParameter>]

Prompts you for confirmation before running the cmdlet.Prompts you for confirmation before running the cmdlet.



Required? false

Position? named

Default value false

Accept pipeline input? false

Accept wildcard characters? false



-WhatIf [<SwitchParameter>]

Shows what would happen if the cmdlet runs. The cmdlet is not run.Shows what would happen if the cmdlet runs. The cmdlet is not run.



Required? false

Position? named

Default value false

Accept pipeline input? false

Accept wildcard characters? false



<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

ErrorAction, ErrorVariable, WarningAction, WarningVariable,

OutBuffer, PipelineVariable, and OutVariable. For more information, see

about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).



INPUTS

None



This cmdlet accepts no input objects.





OUTPUTS

System.Object



This cmdlet returns an object that contains the CIM instance information.





Example 1: Create an instance of a CIM class



PS C:\\>New-CimInstance -ClassName Win32_Environment -Property @{Name="testvar";VariableValue="testvalue";UserName="domain\\user"}



This command creates an instance of a CIM Class named win32_environment in the root/cimv2 namespace on the computer.



No client-side validation is performed if the class does not exist, the properties are wrong, or if the server rejects the call.



If the instance is created successfully, then the New-CimInstance cmdlet outputs the newly created instance.





Example 2: Create an instance of a CIM class using a class schema



PS C:\\>$class = Get-CimClass -ClassName Win32_Environment

PS C:\\> New-CimInstance -CimClass $class -Property @{Name="testvar";VariableValue="testvalue";UserName="Contoso\\User1"}



This set of commands retrieves a CIM class object and stores it in a variable named $class using the Get-CimClass cmdlet. The contents of the

variable are then passed to the New-CimInstance cmdlet.





Example 3: Create a dynamic instance on the client



PS C:\\>$a = New-CimInstance -ClassName Win32_Process -Property @{Handle=0} -Key Handle -ClientOnly

PS C:\\> Get-CimInstance ????????CimInstance $a

PS C:\\> Invoke-CimMethod -CimInstance $a -MethodName GetOwner



This set of commands creates a dynamic instance of a CIM class named win32_Process on the client computer without getting the instance from the

server. This set of commands retrieves the dynamic instance and stores it in a variable named $a and passes the contents of the variable to the

Get-CimInstance cmdlet. The Get-CimInstance cmdlet then retrieves a particular single instance, and invokes the GetOwner method using the

Invoke-CimMethod cmdlet.



This dynamic instance can be used to perform operations if the instance with this key exists on the server.





Example 4: Create an instance for a CIM class of a specific namespace



PS C:\\>$class = Get-CimClass -ClassName MSFT_Something -Namespace root/somewhere

PS C:\\> New-CimInstance -CimClass $class -Property @{"Prop1"=1;"Prop2"="value"} -ClientOnly



This set of commands gets an instance of a CIM class named MSFT_Something in the namespace root/somewhere and stores it in a variable named $class

using the Get-CimClass cmdlet. The contents of the variable are then passed to the New-CimInstance cmdlet to create a new CIM instance and perform

client side validations on the new instance.



If you want to validate the instance, for example, to make sure Prop1 and Prop2 actually exist and that the keys are marked correctly use the

CimClass parameter instead of the ClassName parameter.



You cannot use the ComputerName or CimSession parameter with the ClientOnly parameter.
