What you get in Toad for Oracle is the ability to see long running
processes with multiple lines, one per process currently underway. If
I recall correctly, the returned information includes what operation
is underway (eg, physical reads), the % complete, start time, time
remaining and elapsed time. Time remaining has been mostly useless
every time I've had to drill down to this level, but otherwise this
has been relatively useful information.
