Enable Session State Script

Hi,

Earlier we were updating below details in web config manually

Now as part of migration from Sharepoint 2010 to Sharepoint 2013 we had automate the above through power shell as below

// EnableSessionState_Batch.bat

Powershell.exe -Command Set-ExecutionPolicy "Bypass"

Powershell.exe -Command "& {E:\Naga\EnableSessionState\EnableSessionState.ps1}"

Pause

// EnableSessionState.xml

<?xml version="1.0" encoding="utf-8" ?>

<SessionInputs>

<WebAppConfigPath>C:\inetpub\wwwroot\wss\VirtualDirectories\32113\web.config</WebAppConfigPath>

</SessionInputs>

// EnableSessionState.ps1

#-----Input parameters to the script

$snapin = Get-PSSnapin | Where-Object {$_.Name -eq 'Microsoft.SharePoint.Powershell'}

if ($snapin -eq $null)

{

Write-Host "Loading SharePoint Powershell Snap-in"

Add-PSSnapin "Microsoft.SharePoint.Powershell"

}

# Get complete file path (eg:  E:\SP2010\xxxx.ps1)

$filepath = $MyInvocation.MyCommand.Definition                                       

# Get current Directory  file path  (eg:  E:\SP2010)

$directorypath = [System.IO.Path]::GetDirectoryName($filepath)        

# Get current Drive   (eg:  E:\)

$directory = Get-Item $directorypath | Split-Path -Parent             

$InputFile = $directorypath+"\EnableSessionState.xml"

$xmlinput = [xml] (get-content $InputFile)

$item = $xmlinput.SessionInputs

## Start logging

$LogTime = Get-Date -Format yyyy-MM-dd_h-mm

$LogFile = $directorypath + "\EnableSessionState-$LogTime.rtf"

Start-Transcript -Path $LogFile -Force

Invoke-Item $LogFile     

Finally got the result as expected.
