Re: temp file does not exist

Yup. this is correct. that's why I had my 9i databases started even if I had that error in alter database.
This confusion started all because 8i's DBCA creates TEMP as datafile and 9i creates TEMP as tempfile.
Of the 4 instances on that particular server, I had 4 9i instances wherein 2 of them were created as 9i databases
and the other 2 were originally 8i databases migrated to 9i. So when I created the scripts to rename the datafiles (Lazy me shutdown the databases first before
getting a list of all the files and did not bother to start up again to get a dump)...I simply ran a for loop in unix on all known datafile directories...luckily, I know them all! =) So when I ran the scripts and 2 databases had errors and 2 did not...I didn't immediately realize that the same 2 that didn't show any errors were originally in 8i.
Well, at that point, it was 9pm already...so I thought, I'll let it pass overnight and let someone willing and able do the thinking... Thanks for that! Great help!
