Hi,

We are using the setup as below.

The database backup (O/S Copy) is copied to a local drive on the live server (A). This backup is the copied on another machine (B) which is used as test database.

Now,I am planning to use RMAN as backup tool. Since the RMAN backup's are stored in RMAN format, how could i reproduce this in another machine.

Please suggest as i need last day's data for testing purpose. I can't use Dataguard as the test server is not same as live server.


Please suggest an alternative,

Best Regards,

You can just restore in a new host
or
duplicate the database.

Since i need to update the test database regularly, is the option of duplicate database via RMAN feasible? Is there any alternative method..

Thanks,

>>Since i need to update the test database regularly
Depends on volume of Datbase.
If volume is less, export/import will do.
Still RMAN duplication is way faster as it just involves restoring to a point-in-time. You can restore a whole database or select tablespaces.
And all these are done without shutting down the production database and can be scripted.

Do i need a catalog for creating a Duplicate database? Since the target and the duplicate database has same directory structure, i guess there will be less work in duplicating.

Thanks for your help.

I'd suggest that you set up a cronjob or a scheduled job (windows) for the same actions that you'd do if you were doing it manually.

1. delete all old backups
2. delete all of the current DB files
3. copy all the necessary backup files from the prod server
4. Run the duplicate DB command again.
