我通过ODBC连接到MSSQL数据库时遇到问题 . 版本12c或18xe出现问题，我连接的11g版本没有问题 .

返回以下错误：

ORA-02063: poprzedzające line z MAG
28511. 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.
