I made use of export/import to change the database characterset months ago and not longer have the log file for either operation. I just discovered that change notification registrations no longer exist in the database and I suspect this happened during the export/import but I can't find anything in the docs that mention this. Anyone know if exp/imp supports change notification in 10.2.0.5 on RHEL 5?
