我有一个我从任务调度程序运行的应用程序。如果我从我的帐户运行它，它可以正常运行，但是如果我从系统帐户运行它（此帐户在服务器上的权限与我的权限类似（甚至是管理员），但是有一个非验证密码。当我从系统帐户运行它在打开Oracle时失败。我的应用程序不会抛出异常。它只是死亡。但是，事件查看器具有以下内容：

我已经检查了我能想到的所有权限。数据库凭据是Oracle凭据（不是Windows凭据；用户名和密码是连接字符串的一部分）
我正在使用版本12.1.0 Oracle客户端
我感到困惑。
由于您尚未提供任何源代码，所以我只是在这里猜测。要使用特权帐户（SYSDBA或SYSOPER）连接，您需要将DBA特权属性添加到您的连接字符串：
//Connect scott/tiger as SYSDBA
con.ConnectionString = "User Id=scott;Password=tiger;" +
"DBA Privilege=SYSDBA;Data Source=oracle;";
