hi
I trying to recover from loss of all
controlfiles and a datafile which was not backed up using RMAN .
these are the steps i followed
>startup nomount
These are the RMAN commands executed.
{allocate channel c1 type disk;restore
controlfile;sql 'alter database mount';restore database;recover database;release channel c1;}

the recover fails wit the following error

RMAN-03022: compiling command:
recover(2)

RMAN-03022: compiling command:
recover(3)RMAN-03023: executing command: recover(3)RMAN-08054: starting media recovery

Does anyone have any idea what this error is about?

I think in this case the recovery is failiing while trying to recover the non-existent datafile.But how would one know looking at this error stack.
If we perform recovery without RMAN ,Oracle would normally give a decent error

like
<SPAN

style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'; mso-bidi-font-size: 12.0pt">ORA-00283: recovery session canceled due to errors
ORA-01244: unnamed datafile(s) added to controlfile by media recovery but with RMAN the error stack given is totally vague. Has anyone encountered this one?
