Hi,
Need clarifications:
1) why we can't set format for controlfile backup other than %F? (Without specifying %F).
2) Is Manually taking controlfile backup uses the same format as autobackup?
Can we set different format for manual backup?
3) which format is default one - %F or % U? (Different manual shows different)
4) which type of format is being used mostly in the production database.
Thanks in advance

Question 2: you can use any format you like:C:\Users\john\home>rman target /

RMAN> backup current controlfile format 'c:\tmp\controlfile.backup';
Starting backup at 10-SEP-10
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1

I don't understand the purpose of your third and fourth questions. For the first question, you need to consider the command
restore controlfile from autobackup; |

Sounds right. But it has to be fixed name, which may not a good solution during daily works. If I remember right, for control file backup, automatical naming only accepts %F format.
As the latter reply, we need to consider 'restore' command works since 'restore controlfile' only works with autobackup or specified file. So if using fixed name, need to specify it too when restore it.
