restore database;
switch datafile all;
}
找到生产数据库传输过来的归档日志文件,找到最后一个文件
恢复到最后一个归档日志文件序列.
run{
CONFIGURE DEVICE TYPE DISK PARALLELISM 5 BACKUP TYPE TO BACKUPSET;
set until sequence 7939;?
recover database;
}
然后open数据库
生产库有block change tracking
还原库可以关闭
另外,查看恢复的时间点
alter database disable block change tracking;
?
alter database open read only;
select to_char(scn_to_timestamp(CURRENT_SCN),'yyyy-mm-dd HH24:mi:ss') ts from v$database;
这时候,还原库已经搭建完成.
生产库有一个程序,每隔30分钟,会将归档日志传送过来.
还原库这边,只需要定期恢复即可(恢复到6小时之前)
0 */3 * * * /root/testoracle.sh
#!/bin/bash
? source ~/.bashrc
? ? rman target / <? ? shutdown
? ? startup mount
? ? catalog start with '/data/IP' noprompt;
? ? recover database until time "sysdate - interval '6' hour";
? ? sql 'alter database open read only';
EOF
7.把还原库拉起到读写模式.
? ? 如果到了第七步,就有麻烦了.
? ? 这意味着,生产数据库挂了,DataGuard的备机也挂了.
? ? 只能把还原库拉起来暂时作为生产库使用.
? ? 尝试将停留在下午4点的还原库,恢复至下午6点,并拉起为读写模式。
恢复之前
执行RMAN命令
rman:
shutdown;
startup mount;
catalog start with '/data/IP' noprompt;
recover database until time "to_date('20150925 18:00:00','yyyymmdd hh24:mi:ss')";
? ? RMAN执行
RMAN> shutdown;
using target database control file instead of recovery catalog
database closed
database dismounted
Oracle instance shut down
RMAN> startup mount;
connected to target database (not started)
Oracle instance started
database mounted
