30 seconds or more for EM pages to load isn't ideal, I must say

If the latency isn’t bad, one EM should be sufficient. There’s a lot of
if’s… Oracle Cloud has several, but we’re talking millions of targets
there.
Most customers can run sufficiently on 1 EM environment. There’s a lot
of downsides to splitting by region/other, as there’s no central place.

Saw a presentation at OUG Scotland a few months ago that described a
project for Telefonica/O2 to set up multi OMS environment with RAC and a
standby cluster and OMS... you could try the UKOUG for contact information.

We have sites across Canada, it would be nice if we could have multiple
OMS hosts in different geographic locations sharing the same
infrastructure. Network lag is an annoyance at best.
i.e. having multiple OMS hosts taking connections from DBAs in different
geographical locations but which share information as if everyone was
connecting to the same EM12c instance.
I wonder sometimes how Oracle does it, do they have only one EM12c
instance for all their data centre sites, or do they have multiple EM12c
installations per data centre or per bureaucratic section inside their
company.
