How to deinstall 12c grid
Does anyone know how to deinstall the Oracle12c grid (not database) software from Linux when the Oracle-provided deinstall program fails? I made a mistake trying to install a PSU patch after installing the Oracle12c grid software for a new, three-node RAC system. I have no user data to worry about yet in this new, test system. I just want to be able to re-install the grid software, then carefully apply the PSU patch this time. But, when I tried the deinstall that is part of the Oracle12 install now, it left (at least most) of the $GRID_HOME software in place.
