Enable Enterprise Manager Express

Database is the marquee feature again

It is the one thing the big sign on Moscone West screams. “The Autonomous Database” Here is a picture from showing it. It is all about database. Every year there is talk about how Oracle needs to return to data and databases. Now that they do, I think we should be […]
