AK - Congratulations on getting Robert's book. This issue of recovering the controlfile depends somewhat on which Oracle version you are using. I think this is easier in Oracle 9i. I started working on Oracle 8i recovery before Robert's book was available. I was not able to recover the controlfile from the RMAN backup. I found it easier to ALTER DATABASE BACKUP CONTROLFILE TO 'XXX'; after the RMAN backup. I included that in my RMAN script and have been able to recover databases on another server.

Can you reply to this before heading to IOUG .  

I am testing restoration controlfile from RMAN backup . with nocatalog option .  

Is there any way you can recover controlfile if database is not mounted .  

I used dbms_backup_recovery package as described in Robert's book . But looks like lost somewhere because after restoring control file database complains system01.dbf is from past backup . Logically seems okay , scn in control file might be different then what is in datafile header . But now what ?
I try to recover database and it is saying recovery using backup controlfile must be done.  

I am lost . any I idea what I am doing wrong here .  

thanks,
-ak
