This may not be the definitive answer, but it is a start...
The following options are not required for Oracle RAC:
AMD VALID 22.214.171.124.0 OLAP Catalog APEX VALID 3.2.1.00.1 Oracle Application Express APS VALID 126.96.36.199.0 OLAP Analytic Workspace
CONTEXT VALID 188.8.131.52.0 Oracle Text
EM VALID 184.108.40.206.0 Oracle Enterprise Manager ORDIM VALID 220.127.116.11.0 Oracle Multimedia SDO VALID 18.104.22.168.0 Spatial XOQ
VALID 22.214.171.124.0 Oracle OLAP API
That should be a start.
Note that some of the above may be required by your applications.
Thank you. I have moved the discussion to the proper group.
I think you started this thread in the MOSC community ( communities.oracle.com ),
but have now moved it to the free public OTN forum community ( community.oracle.com ).
(Your thread ID number suggests that and users can't move their posts on the free OTN site.)
That may be just fine, but there are different levels of responses between those two arenas.
