oracle技术之oracle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
