There is an OEM pack that does this as well as some 3rd party tools (I think Quest has one), but I don't recall seeing a supplied package that did this. You could use dbms_metadata to extract all the objects for the two schemas then run a diff on the files. Regards, Daniel Fink sol beach <sol.beach@xxxxxxxxx> wrote: I'm having a senior moment. I would have sworn that an Oracle supplied DBMS_* package exists which compares two schemas. If it exists, whatis its name? TIA P.S. I have googled, searched both Metalink & OTN & have struck out (so far).
