Oracle 8i database data recover problem

Question

Hi hi,
I've recently encountered a problem on how to restoring data from old oracle folders to a new oracle 8i database.
Originally, my oracle 8i was installed in windows 2000 server on a harddisk (J:\oracle old) separated from that the OS (windows 2000 server) resided. Recently, the harddisk with the OS has been permanantly demaged and I've installed windows 2000 server on a new harddisk (C:\winnt), reinstalled the oracle database (J:\oracle).
However, is there any way to recover the data from an instance of the original database to the newly created database.
I will be grateful for any suggestion? Thanks a lot.

Answer 1

CREATE CONTROLFILE
Caution:
Oracle recommends that you perform a full backup of all files in the database before using this statement. For more information, see Oracle9i User-Managed Backup and Recovery Guide.
Purpose
Use the CREATE CONTROLFILE statement to re-create a control file in one of the following cases:
All copies of your existing control files have been lost through media failure.
You want to change the name of the database.
You want to change the maximum number of redo log file groups, redo log file members, archived redo log files, datafiles, or instances that can concurrently have the database mounted and open.
Note:
If it is necessary to use the CREATE CONTROLFILE statement, do not include in the DATAFILE clause any datafiles in temporary or read-only tablespaces. You can add these types of files to the database later.
An alternative to the CREATE CONTROLFILE statement is ALTER DATABASE BACKUP CONTROLFILE TO TRACE, which generates a SQL script in the trace file to re-create the controlfile. If your database contains any read-only or temporary tablespaces, that SQL script will also contain all the necessary SQL statements to add those files back into the database.
