    hostname similar for 2 servers

    Hi all,

    Do I get error if I Install Oracle 10g on both 2 Linux servers with the following /etc/hosts

    server1 > 119.111.9.1 orasvr1.abc.com.ph orasvr1
    server2 > 119.111.9.2 orasvr1.abc.com.ph orasvr1

    The aliases are the same but the IPs are not

    Thanks a lot

    You got a duplicate name on the network, don't you?

    Next time Dave tells you it is not a good idea to jump from the bridge with your hands tied on your back... trust him and don't do it.

    then server 2 has a different name doesnt it

    You probably want an active passive IP cluster set up where the OS deals with if one machine is down

    Dear Reeshe,

    RAC is based on concept of failover of VIP (Virtual IP's) from the failing node to the other node in Cluster.
