Q

Lost archived redo log files

I'm working on Oracle 9i. I've lost my redo log files. Do you know how I can recover the database?
If you have lost an archived redo log file, then your database is fine, so long as you do not have to recover the database. If you lose an archived redo log file, take an immediate backup of your database so that you do not need the missing archived redo log file.

If you have lost an online redo log file, then you can recreate it by opening the database with the RESETLOGS option. You can perform the following steps:

CONNECT / AS SYSDBA
STARTUP MOUNT
ALTER DATABASE OPEN RESETLOGS;

Your missing online redo logs will be recreated. Since you performed a RESETLOGS operation, it is a very good idea to take a backup of your database immediately.
