    Output of ifconfig -a command is:

    en0: flags=5e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
    inet 10.10.0.1 netmask 0xff000000 broadcast 10.255.255.255
    tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0

    en1: flags=5e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
    inet 192.168.100.5 netmask 0xffffff00 broadcast 192.168.100.255
    inet 192.168.100.7 netmask 0xffffff00 broadcast 192.168.100.255
    tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0

    lo0: flags=e08084b<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT
    inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
    inet6 ::1/0
    tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

    192.168.100.7 is configured as virtual IP after Oracle RAC installation.

    Is the above output expected or should the Virtual IP be dispayed for en0: flags=5e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
    inet 10.10.0.1 netmask 0xff000000 broadcast 10.255.255.255
    tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0

    en1: flags=5e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
    inet 192.168.100.5 netmask 0xffffff00 broadcast 192.168.100.255
    inet 192.168.100.7 netmask 0xffffff00 broadcast 192.168.100.255
    tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0

    lo0: flags=e08084b<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT
    inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
    inet6 ::1/0
    tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

    192.168.100.7 is the virtual IP configured during Oracle RAC installation. Shouldn't it be configured for vi0 interface? I need to change the IP address for VIP as well as the physical interface.

    Regards,
    Bruce.

    are you sure you want a VIPA setup in aix? Oracle RAC will use IP Aliases for its VIPs to my knowledge. and that's what your pasted output looks like anyway.
    aix 5.2 is out of support for some time already
