Scripting AEM Oak Compaction

Offline compaction is still the Adobe recommended way of compacting Oak. Below is a script to help automate the entire process. Please keep in mind that you will need to download a version of Oak Run that matches your repository version.

  1. Shutdown AEM
  2. Find Old Checkpoints
  3. Remove Unreferenced Checkpoints
  4. Compact Oak
  5. Restart AEM

Each step will log basic information into a file using the current date. The stop and start processes specifically write the exact time they were kicked off.

Note: I've taken the liberty of adding a few arguments to the compaction process to help with memory issues. You can read about tar memory mapping here.
