Ora9i physical stby db failover-recover to the last committed transaction

Question

Example: The primary db is not accessible. But we can still access the archived and online redo log files (physically in OS).
How to recover to the last committed transaction (on primary db) while we do failover on standby?
I just able to recover to the last transaction in the last archived redo log.

I register and apply all archived log files to my standby db before perform failover.
SQL> ALTER DATABASE REGISTER PHYSICAL LOGFILE 'filespec1';
But I just able to recover to the last transaction in the last archived redo log, not the last commited transaction in (current) online redo logs in primary db before it breaks down.You can copy & apply all the archive log files, If you want to apply even current redo log file use below command
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE;

Hope that file is not corrupted, But before that create a restore point for safe side if any recover issues you can flashback to that point.
Until you have archive logs if you applied safely you can open database by performing failover.
If you apply using Redo log files, it may cause some consistency.
Or perform until TIME based recover as
SQL> recover automatic standby database until time '2011-11-17 14:00:00';
