Thanks for the response. Yes, we will be upgrading to Oracle 8i EE from 8.0.5.1 very soon. I'm just worried about how long it will take to apply all the accrued redo logs that are generated while the standby db is open and in read only mode. I need to try and figure this out how many redos are generated in the production db in a 24 hour period. If it would take more than 3 or 4 hours to put standby back in recovery mode and apply all these logs, they may not want to go this route.

Thanks for the input!
