Very useful information. Thank you for sharing. I downloaded orachk and used it and is really great. Regretfully, under my care are some importabt instances running on Windows servers. Do you know if by any chance Oracle is planing to create or is there already something equivalent to orachk than can be run on Windows environments?

Best regards,
