The /rman on the auxiliary server is indeed on the same spindles as the rest of the datafiles, but I thought I'd ask anyway. The recovery process is going through the "cataloged datafile copy" for each datafile in the instance. Messages like this: cataloged datafile copy datafile copy filename=/u10/oradata/stage/txbill_idx13.dbf recid=210 stamp=640430010 However, each of these take 3-4 minutes, judging by the duplication log updates. When I have hundreds of datafiles, 3-4 minutes each is an incredibly long time. Nothing is being written to the aux instance alert log during this period. It seems that since we moved production to 64-bit hardware, this duplications went from 9-10 hours (which I thought was way too long) to 25-26 hours (which is a horrible joke). I'm going to pour over some of the online guides and Robert Freeman's 10g RMAN book. If anyone has any tips or cluebats, swing away. -- Don Seiler http://seilerwerks.wordpress.com ultimate: http://www.mufc.us -- http://www.freelists.org/webpage/oracle-l
