Should be but are not.

Sequences can be a problem in RAC ... they are not with stand-alone.

Optimum primary key design can, depending on the application, include a column for instance number ... irrelevant with stand-alone.

One of the best sources of information is: http://www.oracleracsig.org/

Also look, on the web, for presentations by Erik Peterson, Kirk McGowan, and Nitin Vengurlekar of the RAC Pack.
