【Oracle Logfile 恢复】已归档、非当前的 Redo LogFile 损坏

[日期：2013-03-31] 来源：Linux社区作者：linwaterbin [字体：]

背景：

今儿个想要练习一下 rman 的增量备份、原本测试库是非归档模式

于是乎、shutdown 掉实例后、open 实例竟然淘气地起不来

sys@Oracle10> alter database open;
alter database open
*
ERROR at line 1:
ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: '/u01/app/oracle/oradata/oracle10/redo01.log'

在这里、我们大概可知日志组1的日志文件损坏了

查看 v$log 视图

sys@ORACLE10> select group#,sequence#,archived,status from v$log;

GROUP# SEQUENCE# ARC STATUS
---------- ---------- --- ----------------
1 2 YES INACTIVE
3 1 YES INACTIVE
2 3 NO CURRENT

可以知道、改组是非当前状态、而且已经归档

用 clear 命令重建该日志文件

sys@ORACLE10> alter database clear logfile group 1;

Database altered.

如果该日志组还没有归档、则需要：

alter database clear unarchived logfile group 1;

打开数据库、然后建议重新备份数据库

sys@ORACLE10> alter database open;

Database altered.
