AEM OAK Offline Compaction on Remote Windows Server
Disclaimer:
This is just a custom guide to run compaction on AEM Author/Publish service on remote windows server, this could be more technical and advanced guide, if you do not understand or don’t know what you are doing, I kindly request you to take extreme caution. The components used here are billable. SKYDEVOPS/I/WE do not take any responsibility if the guide causes any serious damage or issues, which you have to take full responsibility.
Tools Needed:
- Download Oak-run JAR form here
Step-01: Create a Free style Job on Jenkins
Step-02: Setup a parameterised 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
