How to perform Oracle database recovery with a corrupt online redo log

I am running Oracle 9i database in CentOS 4 in NOARCHIVE mode. Recently, I tried to start it up but the database was not able to reach open state (it can only be in mount state). This is the output I've got:

SQL> ORACLE instance started.

Database mounted.

ORA-00312: online log 2 thread 1: '/oracle/oradata/hqdb/redo02.log'

I have a database export dump. I do not know much about recovery of the Oracle database. I would prefer to recover the database than create a new database and import. Can you help?

STARTUP MOUNT
ALTER DATABASE OPEN RESETLOGS;
