In that case, the config option should be used for that. If it's set, don't even bother checking whether you can do privledged ops, and just assume you can't; also, don't bother creating the proc files. If it *is* set, then you still have to check, as the instance may not have been given the nescessary privs. ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
