oracle用备份的控制文件恢复后不用resetlogs打开方式的恢复

在一般恢复备份

的控制文件,打开数据库

都要
用resetlogs 重置日志这种方式,

这是因为备份的控制文件恢复后,没有最新的当前在线日志信息 ,而重建控制文件

就
可以用 NORESETLOGS 这种方式打开

这是因为:

备份的控制文件里面有一个 截止 SCN

.F S?1]GI1`�VB$L467815
正常关闭的数据库的控制文件里面也
有一个截止scnITPUB个人空间E{/_jV3@/;d/

正
常打开的数据库的控制文件截止scn是无穷大(crash 也是)ITPUB个人空间$y
c5wC3gU

重新创建控制文件的截止SCN也是无穷大，也就是apply日志文件直到scn达到截止scn，于是这就导致你
应用完了所有归档的日志还没有达到这无穷大，open的时候数据库认为是非正常关闭进行崩溃恢复，自动应用了所有联机日志

操作方法:

使
用旧的控制文件mount 然后 alter database backup controlfile to trace ，restore
database 然后手工创建控制文件，使用 reuse database pubtest noresetlogs .这样就可以
recover database 自动恢复并open database 而不用 resetlogs 了ITPUB个人空间'S6s1HPR
