This is a short blog answering the question: "I have a cron job running as a non-tungsten user, and that job needs access to the tungsten-owned files under /opt/continuent, but cannot access the files it needs - how do I give access to those files to my cron job?"

Performance tuning any system provides more speed for the same hardware spend, gives the end-user a better, faster experience and typically reduces the stress on staff all around. Security tuning locks down critical data to prevent unauthorized access. Today we will explore both the security and performance enhancements available for the Tungsten Replicator THL sub-system as of version 7.x.
