Duplicate Database with RMAN is as easy as it should be

Oracle Enterprise Manager gets bigger with Sun Opscenter

I was on the Sun Oracle event here in Istanbul, Turkey on 28.04.2010. The main course was about engaging Oracle with Sun.

The most interesting part for me was the future of Oracle Enterprise Manager. There were a lot of clue for it is going to get bigger, not only for database and application server management but also in virtual machine (both on Solaris and Enterprise linux) and operating system management (Solaris, Redhat Linux and Suse Linux).

Oracle has already began to integrate Sun Opscenter to the Oracle Enterprise Manager. Main idea is single handed management of a datacenter with Oracle Enterprise Manager.


There are some links about this topic.
