Hi,

I want to create binary copy of control file every time I do backup.
I am using sql "alter database backup controlfile to ''+FRADG/TESTDB/controlfile/controlfile.ctl'' "; in my rman backup script.
If I run it second time I got errors as it does does not allow to overwrite existing one.

Thanks

REUSE option let's you do that.

ALTER DATABASE BACKUP CONTROLFILE TO '/location/file.bak' REUSE;

The REUSE option allows you to have the new control file overwrite a control file that currently exists.

Read the docs, http://docs.oracle.com/cd/F49540_01/DOC/server.815/a67773/osbackup.htm#5747

Regards,
Lalit

Thank you Lalit! Also if you can point me if there is any way to use 'format' in this statement
i.e sql "alter database backup controlfile to ''+FRADG/TESTDB/controlfile/current_%d_dbid%I.ctl'' "; This won't work but may something similar .. using % etc..
I can user CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '+FRADG/TESTDB/controlfile/controlfile_%F.ctl'; it allows to use %F etc..
But I would like to create a binary copy and not in backup sets...
Sorry if I confused you. I am just learning RMAN

I found it .. I can just use BACKUP AS COPY CURRENT CONTROLFILE FORMAT '+FRADG/TESTDB/controlfile/current_%d_dbid%I.bkp'.

Thanks you again.
Cheers!
