Kevin, is correct in that there will be additional overhead incurred when you run either a RAC database in exclusive or a non-RAC database on the RAC linked binaries. That overhead may be acceptable if you want the option of switching back to using RAC without having to relink the binaries. -- Mark D Powell -- -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Kevin Closson Sent: Wednesday, November 16, 2005 3:22 PM To: oracle-l@xxxxxxxxxxxxx Subject: RE: RAC de-clustering >>> >>>Besides, having Oracle binaries relinked without RAC will not allow >>>to keep one of 3 database as RAC unless separate Oracle home is used >>>(poster mentioned that home is on shared FS).
