ODTUG KScope 11 is coming, YIPPEE!

I’m looking forward to ODTUG KScope 11 in Long Beach next month! KScope 11 (used to be called “Kaleidoscope”) is the only Oracle conference devoted to developers. That’s right, it’s aimed square at you and me; the people who write code that makes systems work. Yes, we get Applications “Functional” people and DBAs, but the focus is on getting the job done. KScope has whole tracks for ADF and Fusion Middleware, APEX, database development with SQL & PL/SQL, MySQL, and Hyperion/Essbase. KScope 11 has sessions for .NET developers, Java developers, and people using LAMP tools too; check it out at http://kscope11.com/. You might know that I’m on the ODTUG (Oracle Development Tools User Group) Board of Directors (http://www.odtug.com). You might not know that I’ve been attending ODTUG since it was the “CASE SIG” at IOUW many years ago. I started attending because the people who speak at the conference are the leading lights in the development community.

JIT

Starting with Oracle 11gR1 Oracle JVM includes Just-in-Time compiler. Its goal is to convert JVM bytecode into platform-specific native code based on the performance data gathered in run-time. It is stated in the documentation that JIT “enables much faster execution” – and this is, in general, true. There are ways to control the behavior of JIT, one way is described in the MOS Doc ID 1309858.1, and another one here.
