Hello : I need to rename an existing database (10.2.3). In the past (about 10 years ago and oracle 7) I was able to take the create controlfile command (via alter database rebuild controlfile to trace), replace the filesystem name and the database name with a new instance name, rename all the filesystems accordingly, execute the create controlfile command and be done. As I said I have not done it in about 10 years. Can this still be done like that? Am I missing anything? thank you Gene Gurevich -- //www.freelists.org/webpage/oracle-l
