Check for an "oracle" user and "dba" group:
$ grep oracle /etc/passwd; grep dba /etc/group

Check if any Oracle processes are running:
$ ps -ef | grep ora

If all else fails, ask the DBA.

Oracle owner may not be named "oracle".
SYSDBA OS group may not be named "dba".

I think Ana's answer is the best one.

Thanks Michel! I was adding to Ana's answer - not trying to provide a better answer. Since when is this a competition anyway?

Sorry, I didn't mean this.
"More reliable way to get the answer" might be a better Smile

way to say what I meant.

Neither solution is 100% "reliable". For example, a client-only install will not have an "oracle" executable.

One should use a combination of the above (and possibly some other) techniques and hope for the best.
