I can't find datafiles in filesystem

I have a working Oracle 8.1.5 instance that someone installed log time ago and I have no docs.
This is Solaris 2.6.

I can't file the datafiles. I search the datafiles where Oracle told me, and I can't find it there. I go to the directory:
# ls -al -> returns 3 files of about 2 MB
# du -s

This returns 600 MB, this matches what Oracle told me the datafiles size was. .But if I do du -s * there is only 3 files of 2 MB.

I need the datafiles so I can migrate this database. What is happening ? what can I do ? Is that in any oracle document I'm missing ?

Thank you very much. Received on Thu Jan 10 2002 - 20:40:14 CET
