使用脚本手工备份数据库的datafile,redo log file,control file到指定目录

OS的版本:

[Oracle@sam tmp]$ cat /proc/version

Linux version 2.6.18-274.el5 (mockbuild@builder10.CentOS.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)) #1 SMP Fri Jul 22 04:49:12 EDT 2011

数据库版本:

SQL> select * from v$version;

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production

PL/SQL Release 11.2.0.1.0 - Production

CORE    11.2.0.1.0      Production

TNS for Linux: Version 11.2.0.1.0 - Production

NLSRTL Version 11.2.0.1.0 - Production

在/tmp 目录下编写脚本

 -- 设置sqlplus环境

 set feedback off heading off verify off trimspool off

 set pagesize 0 linesize 200

 --指定备份文件存放在哪个目录

 define dir='/tmp/wb'

 --告知数据库调用何处的脚本进行备份

 define ws='/tmp/ws.sql'

 --把以下的select输出存放在ws指定的文件中

 spool &ws

 select '!cp ' ||name || ' &dir' from v$datafile;

 select '!cp ' ||name || ' &dir' from v$controlfile;

 select '!cp ' ||name || ' &dir' from v$tempfile;

 select '!cp ' ||member || ' &dir' from v$logfile;

 spool off

 --因为是冷备,所以关闭数据库。注意是干净地关闭数据库,不是abort。

 shutdown immediate

 --调用spool输出在ws中的脚本。此过程是对三类文件的拷贝。文件大小不同,耗时会有不同

 @&ws

 startup

 set feedback on heading on verify on trimspool on

待脚本执行完成后,,该次冷备完成。
