Using RMAN DUPLICATE when the target system is behind a firewall
My production servers are on the other end of a network link where they can not make connections to any of the servers in my dev/test environment, but connections from dev/test to production are fine. This is problematic: OEM 12c (housed in dev/test environment) can't monitor production (needs 2-way agent<->OMS comms) RMAN DUPLICATE doesn't work (requires connection from source to destination) No way to push files from production to dev/test And many others... The point of this post is to talk about RMAN DUPLICATE in this situation. As there's no outbound connectivity from prod->dev/test, I initially assumed this wouldn't be possible, however I've tried using SSH tunnels. and while it didn't work due to my previous blog post (RMAN-05531 during duplicate from active standby), the concept is fine. Log in to the shell of the destination database, and follow the usual setup (DocID 452868.1 ) to create a duplicate from active database: C
