Hi all
We have a server with several Oracle databases and one listener. We need to upgrade just one of these databases with the minimum amount of downtime for the other databases. The database is current on and will go to, two other databases are on this version.
What is the best approach here? We cannot change the application config so it will still need to remain on its current listener.
My background is MS SQL server and fell into accidental Oracle DBA area

thanks in advance Pebble

There is no reason why upgrading one database should have any effect on any other. One listener can enable connections to databases of both versions.
What you you are trying to do is not particularly difficult, just follow the documented upgrade procedure. And ask if something does not make sense to you.

How many Oracle homes do you have on this server? Does the same home service all four databases? What version are they all running?
