I'm a newbie to Oracle and currently have a couple 9i instances and a couple 10g instances. These are being managed by 2 different OEM installations. What I would like to do ideally is install the latest OEM 11g on a Windows server and use it to manage all the instances. So i guess my questions would be: 1) Is it possible to use a newer version of OEM to manager older instances? 2) Is there an installation available for OEM to be installed on Windows that manages AIX Oracle instances? 3) If possible how does that work? I'm assuming that you just put an agent on the AIX boxes and they report back to the Windows server.
