Hi Kart, do you copy init.ora from the 1. standby? Y. Emre Baransel ________________________________ From: K R <kp0773@xxxxxxxxx> To: Oracle-L@xxxxxxxxxxxxx Sent: Monday, May 9, 2011 1:31 AM Subject: controlfile from standby database All, I have a requirement to build 2 standby database on the standby server in 10gR2. and this whole process needs to be automated . So I was thinking to build first standby database using rman duplicate for standby and then for building the second standby -use all the datafile from first standby to copied for 2nd standby -use the controlfile copied from first standby to be copied for 2nd standby I see i am able to get all the datafiles copied without any issue but when i copy the standby file and bring up the 2nd standby it do not show my file_name_convert act properly. appreciate any suggestions. thanks Kart
