您好，请问使用ODC连接Oceanbase mysql模式是否为通过obproxy，如果是的话，请在黑屏连接下检查以下参数

-- 查看当前配置
show proxyconfig like 'client_sock_option_flag_out';
show proxyconfig like 'client_tcp%';


需要确保 

client_tcp_user_timeout > client_tcp_keepintvl


 同时关于proxy推荐以下配置

alter proxyconfig set client_sock_option_flag_out=2
alter proxyconfig set client_tcp_keepidle=5
alter proxyconfig set client_tcp_keepintvl=5
alter proxyconfig set client_tcp_keepcnt=5
alter proxyconfig set client_tcp_user_timeout=0

直连的observer，没有部署obproxy
