Beg to differ

Try select * from v$log_history at one of your test databases.

logswitches are in v$log_history regardless.

So number of switches times the size of the logfiles gives you a pretty
good estimate.

Hello

I do not think that you can estimate the amount of disk space required for
archive log without turning archive log on and checking each day to see how
much space you already used.

To all who replied: I think that you missed his comment that currently he
is
NOT working with archive log on.
