一致性备份（冷备份）

 

1、编写生成备份脚本的脚本

#cold backcup

remark set sql*plus variable to manipulate output         //注释

set feedback off heading off verify  off trimspool off  echo off time off

set pagesize 0  linesize 200

remark set sql*plus user variable used  in this script                //注释

define bakdir='/disk1/backup/anny/cold_bak'                             //备份文件的存放位置

define bakscp='/disk1/backup/anny/cold_bak/cold_cmd.sql'               //执行备份的脚本，自动生成

prompt *** Spooling to &bakscp                        //输出提示语

remark  create a command file with  file backup commands

spool &bakscp

select 'host cp '|| name ||' &bakdir ' from v$datafile order by 1;

select 'host cp '|| name ||' &bakdir ' from v$controlfile order by 1;

spool off;

remark   shutdown the database cleanly

shutdown immediate; ——冷备份需要关库执行

remark run the copy file commands form the operating system

@&bakscp

remark start the database again

startup;

 

2、执行该脚本生成了一个脚本cold_cmd.sql，并执行该脚本进行冷备份

SQL> conn /as sysdba

Connected.

SQL> @/export/home/oracle/sqlplus/anny_cold_bak

SP2-0734: unknown command beginning "cold backc..." - rest of line ignored.

*** Spooling to /disk1/backup/anny/cold_bak/cold_cmd.sql        ——一下是脚本内容

host cp /u01/app/oracle/oradata/anny/lx01.dbf /disk1/backup/anny/cold_bak
