My Oracle database Test server crashed, I have no rman backups but I still have the datafiles because they are on a SAN Storage, so if I have datafiles, how can I restore my Oracle database?

Define "crashed". Have you tried starting it up?– mustaccioSep 22, 2022 at 17:42

I just crashed my car at full speed into a brick wall.
Can I just get back in and drive it away?
Really? Wouldn't you rather get another car? One that's working?
You have no idea what state your server is in, or why it crashed.
Depending on how badly "crashed" it is, you might be able to get it up and running again and do some diagnostic work to find out.
You might not.
Than again, you might not want to. If you suspect that the server was compromised (hacked), your safest option would be to "burn" it and run up a new one.
You have no idea what state the server's disks are in.
Therefore, you have no idea what state your database is in.
It's not want you want to hear, but this is precisely why you must have Backups. Not just of your database, either, but also for the server that you run it on and all the software (including the DBMS itself) that goes with it.
This is I.T.
"Stuff" happens.
You must protect yourself, ready for when it does.
