Linux下Oracle通过ODBC连接MySQL做DBLink问题。

[scbb]

目前ODBC应该配置成功，但是isql可以远程连接MySQL。
但配置Oracle连接MySQL，执行DBLink的Select报错，错误信息下次补。

怀疑是Oracle还是使用了其他端口，因为Linux上配的是最小策略，请问这种情况，哪些端口是需要打开的？

8511. 00000 - "lost RPC connection to heterogeneous remote agent using SID=%s" *Cause: A fatal error occurred in one of the following places -- the connection between the ORACLE server and the agent -- the heterogeneous services remote agent itself -- the connection to the non-Oracle system This error occurred after communication had been established successfully. *Action: Check for network problems and remote host crashes. The problem is probably in the agent software. If so, contact a customer support representative of the agent vendor.

你oracle是怎么配置连接mysql的，是不能直接配的，需要通过配置透明网关再配置连接MYSQL
