I am doing clonging from production using RMAN hot backup pieces which I copied to target same location. I started duplicate connecting with production control file, it finished restore and failed during control file creation. There was control_files parameter which was set wrong in pfile and caused control file creation failure. After altering the control_files parameter to correct value I restarted the duplicate command but it is failing with below error. There is no recovery catalog being used and I also removed the last restored database completely then tried but still getting the below error: Starting Duplicate Db at 24-AUG-10 released channel: c1 released channel: c2 released channel: c3 released channel: c4 released channel: c5 released channel: c6 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of Duplicate Db command at 08/24/2010 08:04:17 RMAN-20207: UNTIL TIME or RECOVERY WINDOW is before RESETLOGS time Environment has ASM file system both in target and source and db is on 10.2.0.5. Any inputs to do the clone will be of great help. Regards, Sha
