RMAN 备份脚本

$cat /home/oracle/db_script/rman/testdb2/rman_testdb2_full.sh
#!/bin/bash
export ORACLE_BASE=/oracle/database
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_SID=testdb2

rman_backup_script=/home/oracle/db_script/rman/testdb2/
rman_backup_dir=/oracle/database/backup/rman/testdb2/
dt=`date +%m%d`

rman target / >>$rman_backup_script/rman_${ORACLE_SID}_full_${dt}.log <run{
backup database format '$rman_backup_dir/db_%d_%T_%s_%p_%t' plus archivelog format='$rman_backup_dir/arch_%d_%T_%s_%p_%t' delete all input;
}
run{
crosscheck backup;
crosscheck backupset;
delete noprompt expired backup;
delete noprompt obsolete;
}
exit
EOF

二问题描述

用上面的脚本备库,看rman日志报错.(脚本中仅对备份出来的文件做check了)
RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 1
using channel ORA_DISK_1
Deleting the following obsolete backups and copies:

RMAN-06214: Archivelog      /oracle/database/arch/testdb2/1_28_741358677.dbf

三原因

某个时候使用操作系统命令将/oracle/database/arch/testdb2/1_28_741358677.dbf　归档日志文件删除.但数据库中却没有将些文件相应状态更新所致.

四操作解决

提示说用crosscheck命令固定状态.
RMAN> crosscheck archivelog all;

released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=138 devtype=DISK
validation failed for archived log

...
...

注意 /oracle/database/arch/testdb2/1_28_741358677.dbf 此无效文件被放在了第一条. 做DBA一定要仔细,不能惯性思考问题.

删除无效归档日志

谢谢张宏伟老师的提示.
