Charles,
I agree GC looks like having some rough edges. but I never had a problem when I upgraded a target.

To my surprise, I got to install the OMS on a RH4, x64 machine (using an existing 10gr2 db). The OMS installed and works flawlessly, while the agent could not link (it's the 32bit version), but I had the x64 version already installed. I repointed it to the new OMS, secured it again, and it's working like a charm.

OEM GC10gR2 is a quite complex piece of software. And I wish developers take time to fix the issues users have with it than to add new features/plugins.

Happy Holidays to all
