SMON offlining US=##-数据库专栏,SQL Server

–转载自  http://www.orafaq.net/maillist/oracle-l/2003/12/15/1191.htm
最近2天我的日志文件中出现了 smon offlining us=## 这样的记录信息
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:
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!
