Since without EM, we DBA's are often in the dark, I appreciate the proposal of RAC for the environment, but doesn't this kill the free licensing option that many companies take advantage of to keep costs down? I would prefer to use my EM monitoring and alert script vs. having to go to my manager and explain to him that I need more budget for licensing costs! Correct me if RAC is free for EM, but I see no documentation saying otherwise. Thanks!

Hi.
Take a look at this:
http://docs.oracle.com/cd/E24628_01/doc.121/e24473/ha_intro.htm#EMADM10659
From your description it sounds like you are only planning a level 1 setup (1 repository instance and 1 OMS instance). If that is the case, I see very little benefit to having it on 2 machines, as opposed to 1. If either DB or OMS machine dies it's all gone anyway. Since the two servers in this setup provide no additional resilience, I would prefer a simpler solution of a single server myself.
Of course, if the plan is to move to a more resilient solution in the future, it may alter my opinion somewhat.
Cheers
Tim...

I now have new clients, new systems to work on and at least two EM12c environments to build out in the near future.
