Grid Control is what is usually known as vaporware - poorly documented, enormous pile of ... stuff, unreliable at best, which will not become really useful before version 13g, if ever. It needs 3 oracle homes, documentation is less then clear, it contains enormous quantities of Java, with XML configuration files and cryptic error messages, Perl scripts and tons of freeware components. It also requires a box with at least 2GB or RAM.
OEM was created by a bunch of cheap programmers, each doing his own thing and a bunch of "system integrators" gathering all of this patchwork into a single, enormous pile of...stuff.
If you need a decent database management product, contact Quest, it's your best bet. As long as OEM looks like it looks now, I am not touching the stuff.
OEM needs to be re-written from scratch, by a decent programming team, with clear vision, ease of use and performance in mind, just like products from Quest. In the meantime, use Nagios with the NRPE plugins. It's much simpler, easier to set up and it doesn't take a monster to run.
