i'm explaining the whole situation

i had running oracle 9i database on a single hard disk , on windows 2003 server, which faced hard disk crash,
i had taken a backup few days ago on RMAN, along with control file,

now i've installed a new hard disk on my server, and also installed oracle 9i enterprise edition.

now RMAN back and control file i've are on a CD,
now from where do i start,
where to copy the RMAN backup and control file on hard disk
which RMAN command sto restore the database from RMAN backup.
my current oracle 9i database does not has previous control files, redo log files or database structure. it has default structure

1. Where did u store the catalog information of the old database ? Is ur catalog is safe or its also lost ?

2. what kind of backup hav u taken last time ? was it an incremental backup or a full database backup ?

3. What was the name of old database ?

4. What is the name of new database ?

Have you already created a new datbase with a new SID?

I think you might be better creating a "shell" of the database (folder structure, and pfile) and then doing something like:

startup mount the db

then in rman:

rman> connect target /;

run {

allocate channel d1 type disk;
restore database;
recover database;

}

then sql "alter database open resetlogs";
in the same rman block

Hi there,

The first thing you need to do is make sure you have an oracle service created, use the oradim utility to do that .. (ask if you need help).

2. Make sure that you have recreated the directory structure as it was on the old server.. you said you already did this.

3. Replace the initdb.ora file (or spfile). The password file will have been created by the oradim utility..

4. Open rman and connect to the target sid that you created using oradim.

CMD> rman target / (if your local on the server)

RMAN > startup

This will fail at the mounted stage because your controlfiles are not there.

Now as long as you have replaced your backup from cd to the C:\ORACLE\ORCLBKUP\ directory you can perform the next steps.

5. RMAN> SET DBID=(your database id..) if you don't know it, look at the backup of your controlfile, it should be part of the backupset name (as well as the timestamp)
RMAN> RESTORE CONTROLFILE FROM AUTOBACKUP;

6. RMAN> ALTER DATABASE MOUNT;

You will now be able to do a list backup because the restored controlfile is accessible.

7. RMAN> RESTORE DATABASE;
8. RMAN> RECOVER DATABASE;
9. RMAN> ALTER DATABASE OPEN RESETLOGS;

Fingers crossed that should be it.

PS In 9i you don't have to allocate channels unless you want to perform actions in parallel, and then it's easier if you just do.. CONFIGURE DEVICE TYPE DISK PARALLELISM 4;

Get back to me if your still having problems.

Good luck.

you could follow the steps, only need change the path of the filenames.
The rman commands in Linux are the same as in Windows.

If you meet any errors, you can post it here, so we can help you.

Hope this helpful.
