Question

在打开与Oracle 11g和Oracle.ManagedDataAccess驱动程序（FileVersion 4.121.2.0）（VB.NET，Framework 4.0）的连接时出现以下错误：

Error Message : ORA-03135: Connection lost contact
Stack Trace :    at OracleInternal.ConnectionPool.PoolManager`3.Get(ConnectionString csWithDiffOrNewPwd, Boolean bGetForApp, String affinityInstanceName, Boolean bForceMatch)

web.config片段（如果需要，我可以提供更多详细信息）：

具有相同设置的此应用程序在我的本地计算机上正常工作，并在服务器上失败。如果我更改对Oracle.DataAccess而不是Oracle.ManagedDataAccess的引用，则该应用程序在服务器上正常工作。

感谢你的时间。
