Environment:
oracle 10.2.0.1.0
Windows XP

I have taken the RMAN Full database backup through the following command.

My database is in no archivelog mode.

AT RMAN prompt
Shutdown immediate;
Startup mount;
run
{
allocate channel c01 device type disk format 'd:\rman_bkp\test_%U';
allocate channel c02 device type disk format 'd:\rman_bkp\test_%U';
backup full database tag 'full_bkup_test_081111';
backup current controlfile;
backup spfile;
release channel c01;
release channel c02;
}

Now i have deleted my all controlfile and spfile/Pfile from the database.

So how can i recover my SPfile and controlfile??
Please Suggest.!!

i do not have autobackup on of SPfile/Controlfile.

Regards

Umesh

restore controlfile from 'your backup file';

Read http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta051.htm#sthref796.

Read your backup logs.
And for the future name the backups of your control file and spfile with a specific name.
Or better activate autobackup.

Most likely the 6MB files are control file backups and the 96KB ones are spfile backups.

And next time, use DOS and copy and paste the result in TEXT mode. No need to waste space
and network bandwidth for this.

Thanks you Michel,

But my concern was like as i can restore any of my datafile which i have deleted.I have not given the path etc, like same cn't i do in case of control file.

coz with my RMAN backup log i have restored my SPFILE/ControlFile,But my concern was if i can restore them as well without giving any path that Oracle should identify itself.

No, you have to give it the path, this is why you should use autobackup.

You need to set your dbid,

set dbid 1278113024;

it is all in the docs, see example 3-44.
