最近2天我的日志文件中出现了 smon offlining us=## 这样的记录信息 【程序编程相关:C#SoapFormatter序列化一例】 【推荐阅读:Microsoft SUS Deploy】我刚开始有些担心是数据库出了问题,经过查找发现是oracle aum的功能: 【扩展信息:Oracle Pro*C/C++游标和存】 this message will be quite common if you are using automatic undo management (aum). as additional undo segments are needed, they are created. after a period of inactivity, smon will offline them. do not fear, they will be onlined if needed.i have a paper about aum on my site at www.optimaldba.com/library.html. --这个地方没有详细内容!
