AEM Application Maintenance Tips and Tricks by NextRow

Abstract

In today’s world, Adobe Experience Manager (AEM) is a comprehensive content management solution for building websites, mobile apps and forms. And it makes it easy to manage your marketing content and assets. Adobe Experience Manager can be a real challenge to architect, deploy, and integrate.

A prime factor here is, you need to understand how your AEM application is performing under certain conditions. This is best done by monitoring the application over a long period of time.

When it comes to managing and maintaining an AEM application, it’s not just system maintenance that we should be concerned about, we should also think of it from the application code perspective.

AEM application maintenance is two faceted. One is ongoing, regular maintenance which falls under AEM DevOps/AEM Administrator tasks. Second is following the best practices in application development.

Here we are going to list out the various aspects of application maintenance from both system and development point of view:

DevOps/Admin Tasks
Online Revision Cleanup:
Every update to the repository such as creating, modifying, or publishing a page/asset, running workflows etc., creates a new content version which gradually increases repository size. In order to improve the AEM application performance and avoid repository growth, the old versions need to be cleaned up to free disk resources. This operation is called Online Revision Cleanup which have been there since AEM 6.3.

Unlike Offline Revision Cleanup (aka Offline Compaction), Online Revision Cleanup doesn’t require AEM instance to be shut down. Online Revision Cleanup is enabled by default to run every day. However, the execution time can be adjusted so that it runs in off-peak hours when there’s minimal activity on the system.

You can find Online Revision Cleanup under Tools > Operations > Maintenance > Daily Maintenance Window.
