Hi,
Everything was running accordingly except with an issue with ENTERPRISE MANAGER which i have posted on the discussion. So while following the supportive answer from the discussion what i did is I tried changing listener and then i got this error messages ORA-01031: insufficient privileges . After then I uninstalled database again and re-tried removing all the listener again and re-tried adding the listener again but that did not wok. I have grid installed in my pc.I have already uninstalled database from dbca therefore I wonder how could i solve the above issue ? I have oracle grid in my pc and here are some information which you might need it.
