Murat,

Whether your in archive log or no archive log mode is a database wide thing. It is not set at the tablespace or object level. As for how much disk will you need, connect to the database with svrmgrl or SQL*Plus as sys and issue the "archive log list" command. Take the oldest online log sequence number, multiple by your online redo log size and divide by the number of days since you created the instance. That should provide you with the average amount of redo you produce per day. Now to be on the safe side, I'd acquire twice that much disk, just in case.

Hi,

how can I calculate/estimate the extra disk space I'll need if I change the log mode from non-archive-mode to archive-mode. I want to change the log mode of all my objects. Do I need to do this one-by-one or is it enough if I change the log mode of my tablesapces?

Thanks in advance

Murat
