12c Release 2

12.2 new features: a first encounter with the new Cluster Health Advisor

One of the many new manuals that showed up in Oracle Database 12.2 is the Oracle Autonomous Health Framework User’s Guide. This book contains a lot of information, some of which we already know from previous releases, and some new stuff as well. One of the new chapters caught my eye in particular:

“Proactively Detecting and Diagnosing Performance Issues for Oracle RAC”

Said chapter 5 introduces a new feature, called the Cluster Health Advisor (CHA), that should help you understand the performance of your cluster better. Really? Time to start the VMs to create a test.

A quick look at Oracle 12.2 performance instrumentation

Thanks to the prep-work done by Andy Colvin, who continuously and boldly goes where no man has gone before, one of our Exadata systems in the lab is now fully upgraded to 12.2.0.1. It comes fully equipped with the matching cellos to support all the cool new features. Exciting times!

The reason for this post is simple: I have started working on our talk for @Enkitec’s E4 conference in June but thought I’d share this little article with you as a teaser :) There might be one or two more of these posts but if you want the full story make sure you catch us (online) during the conference.
