UKOUG Tech13: Day 3 – Virtualization and Oracle 12c Optimizer

By | Technology Survey | No Comments

Another full day in Manchester, I choose to follow a stream a little bit different in the morning. So it will not be all about the Oracle Optimizer 12c today, but more about O.S and virtualization.

Everyone thinks about VMware when speaking about the first…

By | Technology Survey | No Comments

Tech13 – Day 2: 11 different streams with 3 dedicated to the databases. Many interesting topics and it’s sometimes hard to choose to which session attend.

Yesterday was a very busy day at UKOUG 2012: many technical sessions about performances and also a time travel back in the evening. I really like sessions about performances (Oracle Optimizer) and Oracle behinds, but I will not focus on the technical side because it will take too much time (maybe in future blogs!). I will just summarize a little the main interesting topics. I had the opportunity to attend several sessions during this day…

Oracle 12c When we talk about performance issues on SQL statement, it’s really often due to bad/missing statistics and Oracle using the wrong execution plan. In next Oracle database two features may (or not) help us to deal with this topic: Enhanced statistics…
