I went ahead and performed the downgrade. Everything went well except for one oddity. All my PL/SQL (procedures and triggers) were marked invalid after the reinstall. Once I recompiled all of them, everything seemed to be completely back to normal. Not knowing what else had changed, I recovered my backup control, data files and redo logs and all was well. Does anyone know what exactly happened? (running 8.1.6 on NT)
