maximum data size in a remote command

Question

my powershell script sends a file to several clients within customised session using following code (code is shortened) ``` function DoCopyFile { param( [Parameter(Mandatory=$true)] $RemoteHost, [Parameter(Mandatory=$true)] $SrcPath, [Parameter(Mandatory=$true)] $DstPath, [Parameter(Mandatory=$true)] $Session) . . . $Chunks | Invoke-Command -Session $Session -ScriptBlock { ` param($Dest, $Length) $DestBytes = new-object byte[] $Length $Pos = 0 foreach ($Chunk in $input) { [GC]::Collect() [Array]::Copy($Chunk, 0, $DestBytes, $Pos, $Chunk.Length) $Pos += $Chunk.Length } [IO.File]::WriteAllBytes($Dest, $DestBytes) [GC]::Collect() } -ArgumentList $DstPath, $SrcBytes.Length . . . } $Pwd = ConvertTo-SecureString $Node.Auth.Password -asplaintext -force $Cred = new-object -typename System.Management.Automation.PSCredential -ArgumentList ("{0}\{1}" -f $Name, $Node.Auth.Username),$Pwd $Sopts = New-PSSessionOption -MaximumReceivedDataSizePerCommand 99000000 $Session = New-PSSession -ComputerName…

Accepted Answer

You need to create a new `PSSessionConfiguration` (this to not use the default one) in your remote computer:

```
Register-PSSessionConfiguration -Name DataNoLimits #or the name you like.
```

Then configuring the parameter you want (in this case `MaximumReceivedDataSizePerCommandMB` and `MaximumReceivedObjectSizeMB`):

```
Set-PSSessionConfiguration -Name DataNoLimits `
-MaximumReceivedDataSizePerCommandMB 500 -MaximumReceivedObjectSizeMB 500
```

Then create the new session with the `PSSessionConfiguration` you need:

```
$Session = New-PSSession -ComputerName MyRemoteComp -ConfigurationName DataNoLimits
```

in your local Computer.

In this way using the Send-File from posh.org I copy a file of ~80MB size. Bigger size return me outofmemory exception.
