Cannot recover from lost of all the controlfiles without resetlogs?

Question

Cannot recover from lost of all the controlfiles without resetlogs?
I have an Oracle10g (10.2.0.1) database(on RHEL5.0 system) DB10G with a recovery catalog database RCATALLOG. The RCATALOG database is synchronized with theDB10G database.
Then I lost all the current controlfiles and I make the following steps:
SQL> shutdown abort;
ORACLE instance shut down.
SQL> startup nomount;
ORACLE instance started.
[oracle@hostp db10g]$ rman target / catalog rman/oracle@rcatalog
RMAN> restore controlfile;
RMAN> alter database mount;
RMAN> r*ecover database;*
RMAN> alter database open;

Because I did not restore the the controlfiles from the backups, I do not need to open the database with open resetlogs.
Why I cannot open the database without resetlogs? Is any step wrong?
Thank you

Hi,
You restored the controlfile from backup but not the full DB. The Database files header are not sinchronized with your controlfile.
Follow the following steps:
1) Mount your Database and create a backup of the controlfile using:
SQL>ALTER DATABASE BACKUP CONTROLFILE TO TRACE;2) Modify the trace file and recreate the controlfile.
3) At this stage your database is mounted. You need to recover it.
SQL> recover database;
Media recovery complete.4)Open the database after recovery completes.
SQL> alter database open;
Database altered.Done, any problem you can use this link for reference:
