Restore controlfile from tape backup.

Dear all,

I am trying to restore a RMAN tape backup to a server at a DR site. I am referencing the document 73974.1 for the restoration.

I have created a different directory structure, created my pfile with changes to the directory structure and started my database pointing to that created pfile.

Now, i am trying to restore my controlfile from my rman tape backup but in vain.

The rman block i'm executing is as below:

RMAN> run 2> { 3> ALLOCATE CHANNEL c1 type sbt parms 'SBT_LIBRARY=oracle.disksbt,ENV=(BACKUP_DIR=/dev/rmt1)'; 4> restore controlfile; 5> }

It says that 'RMAN-06563: control file or SPFILE must be restored using FROM AUTOBACKUP' but when i run restore controlfile from autobackup, they can't locate the autobackup.
