Conclusion

Starting from Oracle 12C, Oracle has a new OEM Express which enable DBA to monitor, configure and administer their Oracle database. So, far it seems pretty lightweight. I have not played a lot with its features but doesn't seem like as much as the 11G OEM or Grid Control. However, setting it up was a breeze. So, no complain there. I do not have to reconfigure the repository and etc. The setup does not interrupted the Multithread enablement either. Oracle OEM Express let the browser to do the rendering and leaving the database to work on SQL parsings and this letting an overall more pleasant experience using the OEM.

Recently, I did an Oracle 12C (12.1.0.2) install and EM was installed/configured automagically.
