Alguns navegadores possuem algumas análises de segurança quando se acessam a um determinado site para conexão via protocolo HTTPS. No meu caso, estava recebendo a seguinte mensagem ao tentar me conectar no Oracle Enterprise Manager 11g:
“SSL_ERROR_WEAK_SERVER_CERT_KEY”, informando que a chave pública do certificado de seguranca do servidor era muito fraca.
Sendo assim, segue o troubleshooting executado para ser possível a conexão no OEM:
Com o OMS home configurado, executei os seguinte comandos.
./emctl stop oms
./emctl secure oms -key_strength 1024 -reset
./emctl start oms
Depois verifiquei os detalhes do OMS:
[oracle@oem2 bin]$ ./emctl status oms -details
