Entity framework 为Oracle托管数据访问配置Web配置

经过大量的谷歌搜索，我似乎找不到解决这个问题的办法。简言之，我正在MVC/WebAPI应用程序中使用带有EF6的Oracle托管数据访问客户端

当我在本地运行时，我可以成功调用Web API 2控制器中的各种操作。没问题

当我发布到登台服务器时，立即出现以下错误：

“消息：基础提供程序在打开时失败。-内部：Oracle.ManagedDataAccess.Client.OracleException（0x80004005）：ORA-01017:无效的用户名/密码；登录被拒绝\r\n在OracleInternal.ConnectionPool.PoolManager”

显然，当我在本地运行时，用户名/密码很好，所以我觉得我没有把它们放到web.config中的某个位置

这是我的web配置，您可以看到我正在使用整个TNS字符串作为连接字符串中的数据源值。如果我不这样做，临时站点将显示错误-TNS:无法解析指定的连接标识符

修复方法是将reg中的FIPSSecurityPolicy设置为0，而不是默认值1

多亏了这条线索：
