Have you tried to unregister the database and register it again? You will lose some history, but it may resolve the resync issue. As to the error ORA-20999: internal error: found non-null and null site name, this is a custom error. So I would look at the catalog database and see if there's any trigger there which can raise this error. hth Cheers Alan.- Alan.- On Wed, Jul 2, 2014 at 9:48 AM, Uzzell, Stephan <SUzzell@xxxxxxxxxx> wrote: > Hi folks, I’ve struck out searching for this, and wondering if anyone > has any ideas.
