Hi All, I would like to know if anyone has tried the role transition between primary and the physical standby in a real production environment. We have a situation to switch the roles for couple of days. The database size is about one terabyte, version 10.2.0.3 64-bit on Solaris 8. I will be setting up a test bed this coming week. Any comments, advices, and suggestions are most welcome. Regards, Senthil.
