oracle linux and using rear to migrate/upgrade

pyroninaDec 9 2020

Hi - I have made a rear backup of a compute node (OL7.8) and need to move it over to another isolated network, and upgrade some nodes over there. I need to update the IP address to that of the NFS server (of the isolated network) machine (that is hosting the rear backup.tar.gz file) so that upon issuing "rear recover", it will make the network connection and restore the node. Where is the IP going to be, and how do I change it? Or is this even possible?

What do I need to do, and how do I do it, so I can start coding?

If you search the forum you will find the question of how to troubleshoot that exception has been answered MANY time.

First you need to have a database to connect to.

Then you need to provide the proper connection information in the connection dialog. The information you provide depends on the type of connection you are trying to create (basic, tns, etcz).

Typically that exception is thrown when you don't provide the proper host, port or sid/service_name.

Post ALL of the details about the connection information you are entering. That includes the values of any dropdowns.
