有关Oracle数据库的备份情况

时间:2007-11-09 来源:不详作者:迈克DB

?设置数据库为automatic archivelog mode,
#su - oracle
%svrmgrl
svrmgrl>connect internal
svrmgrl>startup mount
svrmgrl>alter database archivelog
svrmgrl>shutdown
svrmgrl>exit
%vi initoracle7.ora
加入log_archive_start = true # if you want automatic archiving
log_archive_dest = $ORACLE_HOME/dbs/arch
log_archive_format = log%s.arc
踫tart
%ps -ef|grep arch
oracle 1743 1 0 15:20:20 ? 0:00 ora_arch_oracle7
注：oracle database is in automatic archivelog mode

?full offline entire database backup, 当数据库初始完成后这份备份是将来备份的基础。它提供了所有与数据库有关
的拷贝.
踫hut
%cp /oracle/oradata/oracle7/system.dbf
/oracle/oradata/oracle7/rbs.dbf
/oracle/oradata/oracle7/temp.dbf
/oracle/oradata/oracle7/tools.dbf
/oracle/oradata/oracle7/users.dbf
/oraclecle/app/oracle/product/7.3.2/dbs/application.dbf
/oracle/app/oracle/product/7.3.2/dbs/apptmpsp.dbf
/oracle/app/oracle/product/7.3.2/dbs/apprlbksp.dbf
/oracle/oradata/oracle7/redooracle.log

织梦好，好织梦

/oracle/oradata/oracle7/control1.ctl
/oracle/oradata/oracle7/control2.ctl
/oracle/oradata/oracle7/control3.ctl
<backup directory>
踫tart
注:以上*.dbf文件为数据文件,*.log文件为日志文件,*.ctl文件为控制文件
%exit
%tar uvf /dev/rmt/0 <backup files>
注:如果为oracle 7.2 ,则copy 相应的 data files,relog files,control files.

6.3、每天做一次 partial online with archiving backups .
#su - oracle
%svrmgrl
%svrmgrl>connect internal
%svrmgrl>alter tablespace billsp begin backup
%svrmgrl>alter tablespace billtmpsp begin backup
%svrmgrl>alter tablespace billrlbksp begin backup
%svrmgrl>alter tablespace system begin backup
%svrmgrl>alter tablespace rbs begin backup
%svrmgrl>alter tablespace temp begin backup
%svrmgrl>alter tablespace tools begin backup
%svrmgrl>alter tablespace users begin backup
%svrmgrl>host cp all datafile to the backup storage. #文件名如第一步中以.dbf结尾的.
%svrmgrl>alter tablespace billsp end backup 织梦好，好织梦
%svrmgrl>alter tablespace billtmpsp end backup
%svrmgrl>alter tablespace billrlbksp end backup
%svrmgrl>alter tablespace system end backup
%svrmgrl>alter tablespace rbs end backup
%svrmgrl>alter tablespace temp end backup
%svrmgrl>alter tablespace tools end backup
%svrmgrl>alter tablespace users end backup

做一个sql文件,如上所写.

The billing system can recover to the point of failure when the failure occur.

七、备份文件的恢复：
　7.1恢复文件：
以下是对＂/etc/passwd＂文件的恢复
　　(、放入正确的磁带
　　(、运行以下命令恢复＂/etc/passwd＂文件
　　# rsh www mt -f /dev/rmt/0 rew
( 找到最近的磁带，向前进带到最近的＂/etc/passwd＂，比如要找星期三的＂/etc/passwd＂文件，运行如下命令)
　　#rsh www mt -f /dev/rmt/0n fsf 2
　　# ufsrestore if www:/dev/rmt/0n
ufsrestore > ls
．：
etc/
ufsrestore > cd etc
ufsrestore > ls
．/etc：
passwd
ufsrestore > add passwd
