Oracle Database 12c R1 ( is finally released!

You can download it from

And now I (and other beta testers) can finally start writing about the new cool features in it! :)

Looks like only the Linux x86-64, Solaris x86-64 + SPARC ports are available first (as usual).

Getting the Most Out of ASH online seminar

Just a little reminder – next week (10-11th June) I’ll be delivering my last training session before autumn – a short 1-day (2 x 0.5 days actually) seminar about Getting the Most Out of Oracle’s Active Session History. In the future it will act as sort of a prequel (or preparation) for my Advanced Oracle Troubleshooting class, as the latter one deliberately goes very deep. The ASH seminar’s 1st half is actually mostly about the GUI way of troubleshooting the usual performance problems (EM/Grid Control) and the 2nd half is about all my ASH scripts for diagnosing more complex stuff.

P.S. I’ll also have multiple very cool news in a few months ;-)

Public Appearances and Exadata Performance Training

I will be doing a lot of (Exadata) talking and teaching in the coming months. Here’s a list of events where you’ll see me speaking, teaching, hacking, learning and hopefully also drinking beer:

Enkitec’s Exadata Smart Flash Cache Hacking Session by Tanel Poder! (free stuff!!!)

We recently received our 3rd Exadata machine into Enkitec’s exalab. Now we have a V2, X2 and X3 there, in addition to ODA, Big Data Appliance (which comes with a beer-holder built in!) and an Exalytics box! So you understand why Karl Arao is so excited about it :-)

This occasion demands that we hack the hell out of all this kit soon! So, let’s have another (super-secret) hacking session!

This time, let’s see how the Exadata Smart Flash Cache works! (both for reads and writes). Note that we won’t cover Smart Flash Logging in this session (otherwise we’ll end up spending half a day on it :)
