HI
<BLOCKQUOTE dir=ltr
style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> 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
