Hi Tom , Again ... changing the OMS for a agent did work ... but after a lot of struggle. As someone said , re-installing agent is faster than debugging it. But this is not the way (atleast for me) a good-matured product works. And important metrics like "usable flash recovery area %" is not alertable and you cannot set thresholds for it. One needs to create a user-defined metric like it. STRANGE !! Thanks a lot Tom , Raj , Alex , Charles & Salem for all your valuable inputs. This is what I expected. I would not prefer to go with 10gR2 GC now. Regards, Prem Khanna J
