Doubt in Oracle base during 12c installation -- Please advise us

Hello All,

I am installing SAP NW7.5, oracle 12c on AIX box in a clustered environment

Please advise us whether i have to mention oracle base is /oracle filesystem or /oracle/SID during oracle 12 c installation.

Here i have mentioned oracle base as /oracle

Please let me know is it correct or i have to mention /oracle/sid.

Regards
