redo size script

Nologging redo size

It is probably easy to calculate hourly redo rate or daily redo rate using AWR data. For example, my script awr_redo_size.sql can be used to calculate daily redo rate, and awr_redo_size_history.sql can be used to calculate hourly redo rate. Hourly redo rate is especially useful since you can export to an excel spreadsheet, graph it to see redo rate trend.

Update: I added another script to calculate redo rate if you don’t have AWR license. redo_size_archived_log.sql.
