Oracle recommends that you use Database Configuration Assistant (DBCA) to create your Oracle RAC database, because DBCA's preconfigured databases optimize your environment for features such as ASM, the server parameter file, and automatic undo management. DBCA also provides pages to create new ASM disk groups if they are needed; if you use ASM or cluster file system storage, then DBCA also configures recovery and backup disk space.

With DBCA, you can create site-specific tablespaces as part of database creation. If you have datafile requirements that differ from those offered by DBCA templates, then create your database with DBCA and modify the datafiles later. You can also run user-specified scripts as part of your database creation process.

DBCA also configures your Oracle RAC environment for various Oracle high availability features, such as services and cluster administration tools. It also starts any database instances required to support your defined configuration.

sorry, and: Creating Templates for Oracle Database (DBCA)
http://docs.oracle.com/cd/E11857_01/em.111/e16599/appdx_creating_db_templates.htm

I have used DBCA generated templates to seed installation of applications into RAC and non-RAC environments (to numerous client sites). It does carry with it wanted options (e.g.. NLS_*) - but I guess the term 'options' may be open to interpretation.

this blog/pdf may assist it assessing what such a template consists of:

(i.e. it steps through making a "lightweight" template for use on a laptop and hence discusses several of the options)
