You Asked

Hi,

I need to install RAC with 19c on RHEL 9.5. Due to compliance clarification I am asked a justification to say GUI is only good option to install GRID, GG and DB.
We have only 6 installations with 4 nodes in each RAC.

I want to go with GUI and want to justify my decision.

Could you please help with this?

I'm going to have to disagree with you here.

There's an old saying for DBAs: "If you need to do something once, do it manually. If you get asked to do it again, then build a script to do it"

The issue with a GUI is

- you'll use a GUI to install it on Dev
- you'll use a GUI to install it on Test
- you'll use a GUI to install it on Production

How do we *really* know all three were the same?

I would recommend scripting this so that the process is repeatable and can be evolved over time as requirements change.

For example, ansible
