I'm new to the OEM so please be patient :)
In my OEM I have an "Microsoft Windows x64" agent, with it I managed to add several appropriate windows hosts.
Now, I would like to add Linux hosts, for which I need a Linux agent.
I have downloaded "Linux_x86_64_Grid_Control_agent_download_11_1_0_1_0".
I do not fully understand how to add it to the OEM (via the GUI interface).
Could someone elaborate how to do it step by step?
I think your question is answered in step 3.1 of this document
