Hi, Check this out http://sources.redhat.com/cluster/wiki/FAQ/CMAN I don't think it necessary to go for any separate NIC For cluster hearbeat , if you are running system with multiple NIC then go with ether net channel Bonding with active passive mode instead of round robin , because with round-robin mode i faced some packet loss that may cause cluster to miss some heartbeat messages. Note: I done an tons of two node RHEL5 Cluster implementation , all works like an charm without any seperate heart beat and more over all are running Oracle DB with more that 3 lakhs transction per day. If you have any more doubt please revert me back On Fri, Jan 29, 2010 at 11:51 PM, Fagnon Raymond <pcs.fagnonr@xxxxxxxx> wrote: > Here are the packages that are installed that I can find.
