Thats precisely what I did. Logged in as Oracle.
1. Tried dd if=/dev/null of=/dev/vx/rdsk/.........../tools_01
2. cat sqlnet.log > /dev/vx/rdsk/.........../tools_01
3. echo "Mary has a little bambi" > /dev/vx/rdsk/.........../tools_01
All ran successfully. I see the timestamp on the raw volume change to
current time. But the datafile is online. I can create tables on the
tablespace (made of only this datafile). I can select on pre-existing
tables. I can successfully do checkpoints. I can shutdown and startup, and
receive no errors.
Either 9i is really robust and unbreakable, or I stay in Utopia.
After typing in all this, I used a file the same size as the datafile, and
specifed the file name as the input file in the dd, and EUREKA!!! I now
have a corrupted data file.

Please respond
to ORACLE-L
Did you try copying a junk file to it. dd if= of=
:) did not think corrupting something would be a problem.

How about
echo "Mary had a little lamb" > /dev/rdsk/
