You are right. If for some reason you did not get the files in the place the controlfile thought they were they will come up MISSING in v$datafile.

I believe this is because the controlfile can't find the file (someone
correct me if I'm wrong). I would check the path and ensure that the
controlfile is pointing to the correct location.

Subject: OCP Question
Listers -
I took the Oracle 10g OCP exam and one question in the exam was
something I have not come across in several years working with Oracle.
I searched google, but only found someone has had this happen, but they
didn't understand why - it was during a database cloning process.
It went something like - You rebuild your controlfile and open your
database and discover several datafiles have been renamed to
/somepath/MISSING##### (where ##### is a 5-digit number).
What might that signify?
A. Those are corrupt files?
B. Those are read-only tablespace files?
C. .....
D. .....
E. .....
I don't remember the five choices, but does anyone know why Oracle would
rename datafiles to .....MISSING#####.
Thanks
