Hi All,
There is a free tool called "orastat" which is available at:
http://dbamon.com/ .
It runs from the UX (would also work on Linux) command line and it
simplifies
various DBA tasks (listing datafiles, tablespaces, users, I/O activity,
...). Here
is some sample output:
orastat -ts (Tablespaces)
orastat | ORACLE SID=PD1 ORACLE HOME=/oracle/PD1
