Yes, direct path reads again 🙂 No worries I’m already a bit bored from digging in this algorithm, so I think this is going to be my last post about it. Till they change it again of course. And yes, in 220.127.116.11 they did.
HROUG,SIOUG and BGOUG. At HROUG and SIOUG I’ll be speaking for Exadata and at BGOUG, maybe for near zero downtime migration or some similar geeky topic 😉 Links to the events: Have fun! Kovachev
In Oracle Database 12c we can find many new and shiny things… So many that we can miss the little good things really easy. I think this one, is one of them.

As simple as that!
A fast and straight approach for creating local IPS repository.
See you there folks!

But actually in Exadata environment this is the algorithm which is balancing the load between the Compute and the Storage nodes. Something really important. As usual, the algorithm is not perfect and for some situations […]
If you try to find out what is HCC and how it works you could start reading the documentation, then some books, blog posts and at the end you will have to put all together. In this post I’ll do exactly this. Put all together. Starting with the basic and going through the internals with […]
