Estou tendo um problema com meu ambiente RAC.Estou usando RedHat 6, Oracle 11.2.0.4 SE.Tenha uma configuração RAC de 2 nós usando ASM.
Ao me conectar usando o SQL Developer, posso me conectar ao meu serviço (dev1.xxxx-dmz.local) se me conectar diretamente a qualquer um dos nós do cluster, mas quando tento usar o nome do cluster, recebo a seguinte mensagem
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
Eu tenho o seguinte cluster CSYA-OR com 3 endereços IP (172.28.1.191, 192, 193) csya-orarac1 (172.28.1.91) csya-orarac1-vip (172.28.1.95) csya-orarac2 (172.28.1.2.2.2.2.2.2.2.2.2.2.2.2.2.28.1.95) csya-orac2-vip (172.28.1.96)

espero que um de vocês possa ver o que está errado. Já vi outras pessoas terem problemas semelhantes online, mas nenhuma das soluções postadas parece funcionar para mim.
obrigado
Solução
O problema era que os endereços VIP não podiam ser acessados pela porta 1521 devido à nossa política de firewall.Esses IPs agora são permitidos e o problema foi resolvido.graças a Balazs por toda a ajuda.
