What is the most efficient, quickest way to completely recreate the database to minimize downtime? The system architecture in question is 10.2.0.4 running on Sun SPARC 64-bit Solaris. This is a 2-node RAC system, using ASM for datafile storage. The background need for doing so is the production database has old "ghost copies" or "ghost data" that is of a sensitive nature in all of the datafiles including the system datafiles, and Oracle has not provided a way to clean this up besides complete database recreation. Thanks, Michael Wehrle
