I did try this a couple of times and got errors and it would never complete. It might have been due to the network.

I got the idea originally, as well as example scripts, from the Oracle Press book Oracle Data Guard 11g.

It doesn't require previous RMAN backups so you don't have to worry about not using it now. Essentially it's duplicating the database across the network using RMAN.

Just be careful not to overrun your network connections if you're not using separate and dedicated network interfaces for data guard.

If you're refreshing a significant part of sizeable databases you might find it more efficient to automate RMAN duplicate across the wire.

Periodically, we get requests to refresh a test database from production to get “up-to-date” data in test. If both production and test are Data Guarded, what is the best way to do the refresh? We would like to not to have to rebuild the test secondary database if at all possible. We don’t use RMAN for backups. We are looking at using Data Pump between production and test and letting Data Guard update the secondary from there.

Is there a better way, without purchasing a tool?

We are using Oracle 11.2.0.3 on Red Hat Linux.

Thank you,
