  }
}

该代码运行无限循环。
在每次迭代时，它执行以下操作10次：

>打开会话
>使用随机数据插入100行
>关闭会话
>显示一条消息，表示没有发生错误

如果发生错误，则会捕获异常并打印其消息
那么执行下一个迭代。

这里是示例输出。正如你所看到的那样，ORA-08177随机地与成功的交互进行交织。

我正在运行Oracle 11.1.0.6.0并使用ODP.NET 2.111.6.20。
将隔离级别更改为ReadCommited修复了问题，但我真的想在Serializable级别运行此级别。
看起来像I’m not alone
有了这个问题，但答案没有给出，所以我再问一次。
我做错了什么，我该怎么解决这个问题？

为了防止任何人咆哮错误的树，发布的代码示例只是ORA-8177错误的生成器。显然实际代码是不同的;具体来说，丢弃和重建桌子是一个红色的鲱鱼。
