You can monitor the databases on different OS and different Versions from EM.
1. What is your EM version?
2. If you are having a 13.3 EM which is the latest one, still you can install the agents on all those 2 Target Servers and monitor the databases of following versions:
22.214.171.124.0,126.96.36.199.0,188.8.131.52.0,184.108.40.206.0,220.127.116.11.0,18.104.22.168.0,22.214.171.124.0,126.96.36.199.0,188.8.131.52.0,184.108.40.206.0, 10.2.0.5, 10.2.0.3,
All you need to do is to Download the agent software and install them on those hosts.
Do you have installed OEM already?
so i create a seperate server
install OEM 13C on this new server
and then install agents on all these database ?
am i right ?
Host A --> Install OMS
Host B (2 10g db on linux) --> Install Agent
Host C (2 11g db on linux) --> Install Agent
Host D (2 12c db on li nux) --> Install Agent
Host E (2 11g db on windows) --> Install Agent
