I created a new DB instance. I wanted to save all my work before I imported the production instance into test. I copied the files to a backup directory. Later, I had to recreate the instance again. However, I felt that since I had saved all the files before that the only file I needed to copy to the backup directory was System01.dbf file. So, I did.
Later, when my import failed (again), I copied the files to their respective directories. When I tried to startup the database I got an error that the date on system01.dbf was not the same as the other files.
Someone told that I had to start everything from the beguining and to save all the files at the same time.
Isn't there a way to re-syncronize all the files?
Does anyone know how?
Thanks in advance.
