brrestore of controlfiles from brarchive session

Hi folks,

I'm using brbackup and brarchive to perform my daily backup with RMAN.

Now I want to rebuild my System from scratch - That means all datafiles; Online and Offline Redologs are gone. at This stage I have all brtool related Log-Information from my Full and Incremental Backup (ending as *.fnr or *.inc)as well the log-Files (ending *.svd) from all of my finished brarchive Jobs.

As I am using RMAN - I suppose that first I have to get first a valid Control-file. As Controlfiles covers Information about Redologs for RMAN recovery I am looking for a way to restore just a controlfile from my last brarchive job (I want to do this with brrestore) and I need to use a brarchive Session because this controlfiles is the most current.

Unfortunately I could not find a way to restore a controlfile from any brarchive-session. If I call "brrestore -m 0" System will restore the control-file from my last brbackup-session. -or- If I try "brrestore -b logfile.svd -m 0" I get a Syntax message "illegal Value for -b"

Is there a way to extract a controlfile from an brarchive session?

thanks for any answer

Alex
