AEM OAK Offline Compaction on Remote Windows Server

Tools Needed:
Download Oak-run JAR form here

Step-01: Create a Freestyle Job on Jenkins

Step-02: Setup a parameterized build job, create a string parameter for remote Host

Step-03: Setup a string parameter for remote User

Step-04: Setup a String parameter for Remote User Password

Step-05: Create a Powershell script to run oak offline compaction on AEM

[code lang=powershell]

# stopping the job if it encounters an error
$ErrorActionPreference = ‘Stop’
$WarningPreference = ‘SilentlyContinue’

# Credentials are stored in env and dynamic variables
$SecurePassword = $env:Password | ConvertTo-SecureString -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList $env:User, $SecurePassword

# Invoke a command on the remote machine.
