How to measure database growth - urgent

[sureshot]

I would like to know how much the database has grown, once a procedure that puts about 600MB of data (based on the network traffic) has run.

Is there a procedure I can use that would give me actual change in the database size before and after?

[svk]

If you know the procedure puts in 600MB of data, for all practical purposes, the database growth IS 600MB.

For an Oracle database, "database size" is either not a defined term or is open for interpretations.

[sysdba]

600M data may take more than 600 space.
check free space (dba_free_space) before and after run to get
a pictur of how much Oracle space is used.
