关闭提供者连接时发生错误…OCI 无效句柄

Question

我进行了很多搜索，试图找出为什么会出现此错误，但没有任何帮助，能否请您指教。

我在执行 linq 查询时收到以下错误

    var test = (Linq query).ToList<Testdata>();

System.Data.EntityException: An error occurred while closing the provider connection. See the inner exception for details. ---> Devart.Data.Oracle.OracleException: OCI invalid handle.

请 send us 一个小型测试项目和 DDL/DML 脚本以在我们的环境中重现该问题。还要指定 Oracle Server 和 Oracle Client 的版本。
