有人在邮件列表里提问，系统表空间文件丢了，没有归档，如何恢复?
来自技术专家 Tim Gorman 的回答：

It’s kind of like voting for president in North Korea. Only one choice — under any circumstances — when in NOARCHIVELOG mode: full database restore from cold backup. There are no options for partial recovery or any recovery at all. NOARCHIVELOG mode = full database restore, no recovery, period. This scenario is no exception.
