I'm having a problem with my RAC environment. I am using RedHat 6, Oracle 11.2.0.4 SE. Have a 2 node RAC setup using ASM.

When connecting using SQL Developer, i can connect to my service (dev1.xxxx-dmz.local) if i connection directly to either of my cluster nodes, but when i try and use the cluster name i get the following message

    Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection

i have the following DNS setup

csya-or-cluster with 3 ip addresses (172.28.1.191, 192, 193)

csya-orarac1 (172.28.1.91)

csya-orarac1-vip (172.28.1.95)

csya-orarac2 (172.28.1.92)

csya-orarac2-vip (172.28.1.96)

output

    $ORACLE_GRID/bin/srvctl status scan

    SCAN VIP scan1 is enabled
