All, I have a situation. I created a physical standby database on 12/15 and I converted it to logical standby database on 12/20 there was a huge batch job on primary that ran on 12/22 which updated 2 big tables of around 150G each .and the updates coming from that batch job is still running since then. I have been always doing the instantiation which normally takes like 4 hour but this time I am thinking if there is a quicker alternative to it .not sure if incarnation will help here. So can I revert back to standby ( 12/19 ) and let the archive logs applied till 12/23 it will be a lot quicker . The database is on 10.2.0.4 Thanks in advance. Kart
