Trying to perform recovery RMAN in OEM. Fails!!!

Question

I am trying to learn to do backups within OEM. I see it uses RMAN behind the scenes.
Anyway, I have 2 databases residing on one machine. A production database "a" and a clone it "b". I performed the cloning in OEM fine.
I then performed a full database backup on "b" using OEM which included the control files. This seemed to go well. I had them created on a mapped drive."s:\"
Now I am trying to use the perform recovery tools in OEM and I can't get anywhere. I am not familiar with RMAN, but I thought that was the purpose of the OEM to provide out of the box solution. The RMAN script generated behind the scenes looks like:
set dbid 1508042233;
set controlfile autobackup format for device type disk to '%F';
run {
allocate channel oem_restore type disk;
restore controlfile from autobackup;
shutdown immediate;
startup mount;
I changed the 2nd line to match my drive mapping 's:\%F';
My error message is as follows and yes it was wrapped this way!

I tried going to the command line and working with it
using the following script:
(Note here i tried working on database "a" which I also have a backup for)
set dbid 21410814117;
connect target
set controlfile autobackup format for device type disk to 'S:\%F';
run {
allocate channel oem_restore type disk;
restore controlfile from autobackup;
shutdown immediate;
startup mount;

from what I understand my two databases dbid's are "a"=21410814117 and
"b" is 1508042233 I have no idea where this other one is coming from.
Any help would be appreciated. I wouldn't mind being able to do it at the command line, so at least I would have an idea of what is going on, but the OEM doesn't seem to work at all.
Thanks,
John

Do one thng. Keep the target db in nomount mode and then run recovery using OEM.
