Hi All,

I am working on 11gR1 database on linux environment and suddenly the DB went down. I look at the alert log and i am following that guidelines, but i am not able to put the database in mount state and it is thronging error message. Please suggest me in correct way. This is very high priority for me.
I have done below steps.

1.set the environment through . oraenv
2. export ORACLE_SID

3. SQL>startup nomount
ORACLE instance started.

********************* ATTENTION: ********************
The controlfile header block returned by the OS
has a sequence number that is too old.
The controlfile might be corrupted.
PLEASE DO NOT ATTEMPT TO START UP THE INSTANCE
without following the steps below.
RE-STARTING THE INSTANCE CAN CAUSE SERIOUS DAMAGE
TO THE DATABASE, if the controlfile is truly corrupted.
In order to re-start the instance safely,
please do the following:
(1) Save all copies of the controlfile for later
analysis and contact your OS vendor and Oracle support.
(2) Mount the instance and issue:
ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
(3) Unmount the instance.
(4) Use the script in the trace file to
RE-CREATE THE CONTROLFILE and open the database.

Please let me know, how i need to proceed. Major problem is i am not able to put the db in mount state. I have both spfile and pfile.

Thanks in advance.
