不知道大家做没做过oracle的全备加归档日志的恢复,我今天早上做了一遍,MTTR大概需要15分钟的时间,大概还算是快速的恢复时间...
原文地址:http://www.5thinknet.com/blog/?p=191
下面我贴上步骤吧...大家做到的时候有个借鉴,这是基于LogSeq的恢复...
其实真正的恢复有好几种,还有基于SCN的恢复.
192.168.150.112 服务器恢复到192.168.150.124的步骤...
首先拿一份192.168.150.112上的spfile[spfileora10g.ora],
覆盖到192.168.150.124/opt/oracle/product/10.2.0/db_1/dbs
telnet 192.168.150.124

su - oracle
ftp 192.168.152.8
lcd /opt/oracle/arch
cd /opt/backup/data/dump
bin
get current.tar.gz(20080825.tar.gz)
bye
cd /opt/oracle/arch
gzip -d /20080825.tar.gz | tar -xvf
[oracle]> cd 20080825
