    Can you ping the IP address of rac1-vip?

    If you can alter tnsnames entry to use IP address instead of dns name.

    Thanks for your reply sir. I tried to ping my VIP address which is but no response. Is there any point I am missing?, I configured VIP explicitly with VIPCA and it is successful.
