Running AEM in Production Ready Mode

How to run AEM instance in Production ready Mode.

In order to run AEM in production ready mode all you need to do is add the nosamplecontent via the -r runmode switch to your existing startup arguments:

Production readymode/nosamplecontent runmode without ant Database:

java -jar aem-quickstart.jar -r nosamplecontent

Production readymode/nosamplecontent runmode with database :

java -jar aem-quickstart.jar -r author,crx3,crx3mongo,nosamplecontent

-Doak.mongo.uri=mongodb://remoteserver:27017 -Doak.mongo.db=aem-author
