Thanks for replying back... Actually my question was where do we implement Grid Controlling? I mean if we have 2 node rac is it wise to implement GRID controlling? or OEM is just fine?
You have to Install OEM Grid Control on any machine or directly at server and configure accordingly with all your RAC enables instances and do the administration with OEM Grid Control.
OEM is different then OEM Grid-- this is for the managebility of more than one Instances.
