Re: RAC background process question

Rick

    Specification of these background processes are instance specific. So, if you have specified 10 DBWRs, then 10 DBWRs will be started in that instance. Every instance will have at least, minimally required background processes for a RAC instance such as LGWR, DBWR, PMON, LMD,LMON proceses etc..
