Re: RAC background process question

DBWR is DBWR is DBWR. In RAC, pretty much all your single-instance knowledge is still valid. DBWR behaves pretty much the same as it does in single-instance. You'll have a few additional background processes in RAC, but all the single-instance processes will also be present in RAC and they have essentially the same function.
