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:
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
Difference between Dafault runmode and nosamplecontent runmode
