Today I have built in my OL 7.3 VM two container databases to verify the new feature in the Enterprise Manager 12c Database Express login screen where I can go direct into a container.

Read MoreOTN Appreciation Day: The Recyclebin
Tim Hall has initiated in his blog the OTN Appreciation Day, this is my contribution to this nice idea. My favorite database feature is not rocket since, not high available, it is very basic.
