Install them using OFA in a different Oracle_HOME directory. /etc/oratab has the home directory per SID. If you are using oraenv to set your env vars (which you should do instead of hardcoding them) $ORACLE_HOME and all related env vars will point to the correct directories, as oraenv reads the oratab.
Evidently, this is documented in the installation manual.
