Rman Crosscheck删除失效归档
作者：eygle |【转载时请以超链接形式标明文章出处和作者信息及本声明】链接：http://www.eygle.com/archives/2004/12/rman_crosscheck.html
当手工删除了归档日志以后，Rman备份会检测到日志缺失，从而无法进一步继续执行。
所以此时需要手工执行crosscheck过程，之后Rman备份可以恢复正常。
1.Crosscheck日志
$ rman target /
Recovery Manager: Release 9.2.0.4.0 - 64bit Production
Copyright (c) 1995, 2002, Oracle Corporation. All rights reserved.
connected to target database: AVATAR2 (DBID=2480694409)
RMAN> crosscheck archivelog all;
using target database controlfile instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=25 devtype=DISK

2.使用delete expired archivelog all 命令删除所有过期归档日志:
RMAN> delete expired archivelog all;
released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=12 devtype=DISK
List of Archived Log Copies

.....
3.简要介绍一下report obsolete命令
使用report obsolete命令报告过期备份
RMAN> report obsolete;
RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 1
Report of obsolete backups and copies

4.使用delete obsolete命令删除过期备份:

Do you really want to delete the above objects (enter YES or NO)? yes

OEM存储的归档日志是不显示了，但v$archived_log中的记录还在呀，怎么清除?
Posted by: Ryan at January 10, 2005 5:27 PM
v$archived_log中的信息是记录在控制文件中的，跟控制文件的记录时间有关。

什么是过期归档日志?
为什么我的归档日志文件已经有40多个了，但是却没有过期归档日志？
Posted by: cxf at July 29, 2008 2:43 PM
那要看你有没有备份过?
