Oracle Resource Manager – Oracle Autonomous Data Warehouse..!! By Vivek Sharma

I recently presented a Full Day Tech Event on Autonomous databases (ADB) for the North India Chapter of All India Oracle User Group. Since most of the attendees were Database Administrators, it was important to cover technical aspects of ADB. While Oracle doesn’t publicize the Internals of ADB, I spoke about some of my experiences based on many of POC’s.

Many DBA’s still assume that 18c Database is Autonomous? Therefore it is Important to know What is Autonomous Database and What it is not? First thing to note is that 18c is not Autonomous. 18c is just like any other Oracle Database. Autonomous uses the features of Oracle Database 18c, plus 12c, plus 11g, plus 10g and so on. Autonomous Database ensures that all these features work together. So, 18c is one of the Building Blocks of 18c. Autonomous uses all the features that Oracle Developed for almost 2 decades. The other important underlying technology is Oracle Exadata, which is the fastest Oracle Database Machine with redundancy built-in at each layer. Again, Oracle had been working on many features that makes this machine a powerful database machine, in terms of Performance, Reliability and Scalability. The Journey had been long from Smart Scans to Direct-to-wire protocol to Smart Fusion Block Transfer and the enhancements continue. One important thing to note is – Customers do have an option to move to 18c on Exadata within their own Data Centre. Then does it mean, this combination is Autonomous? The answer is NO. The two components are critical, but what makes it Autonomous is the Cloud Automation with Machine Learning.

During the session, I covered the Performance features and the way Oracle controls resource utilization. The topic that came up was Oracle Database Resource Managers. Database Administrators were more inquisitive to know more about this and how it is been implemented in ADB.
