以前大家了解了Oracle数据库的在线备份，另外，进行数据库全备份后需要备份归档的日志文件。

1. 建立数据库备份的脚本

在上面建立的目录下建立如下的两个脚本。

1.1 建立执行备份任务的脚本（批处理文件）

文件内容如下：

@echo OFF

Rem ====================================

Rem NAME - archive_backup_Run.bat

Rem FUNCTION - Creates a backup script for a User Managed backup

Rem NOTES - This script will create a script and run OS copy commands

Rem on closed （cold） database

Rem MODIFIED - ksmith 01/01/02 Original File

Rem ===============================

Rem For Windows， set environment variables for the root path.

set ORACLE_SID=TSTDB

set ORACLE_CONNECTSTRING=tstdb

set ORACLE_BASE=c：\oracle

set ORACLE_HOME=%ORACLE_BASE%\ora92

set ORACLE_DATA=%ORACLE_BASE%\oradata\%ORACLE_SID%

set ORACLE_ADMIN=%ORACLE_BASE%\admin\%ORACLE_SID%

%ORACLE_HOME%\bin\sqlplus /nolog @archive_backup.sql 》 archive_backup.log

1.2 建立完成备份认为的命令文件（sqlplus内执行的sql脚本）

文件内容如下：

Rem ===============================

Rem NAME - archive_backup.sql

Rem FUNCTION - Creates a backup command file for a User Managed Archive Log backup

Rem NOTES - This script will create a script and run OS copy commands

Rem on an open or closed database.

Rem MODIFIED - Mr. Tianliang Guo 2002/08/19

Rem ==========================================

Rem Set SQL*Plus variables to mani***te output

set feedback off

set pagesize 0

set heading off

set verify off

set linesize 150

set trimspool on

Rem Set SQL*Plus user variables used in script

define adm = ‘sys’

define pwd = ‘oracle9i’

Rem for Windows

define dir = ‘C：\oracle\admin\TSTDB\backup\archive log’

define fil = ‘archive_backup_commands.sql’

define spo = ‘archive_backup_output.lst’

define cpy = ‘copy’

Rem login database

connect &adm/&pwd as sysdba;

Rem Create a file containing all the file copy commands needed for open physical backup

spool &

prompt spool &;

prompt alter system archive log all;;

SELECT ‘host &cpy ’||name||‘ &dir’

FROM v$archived_log

WHERE completion_time 》= trunc（sysdate）-1

AND completion_time 《 trunc（sysdate）;

prompt spool off;;

spool off;

Rem Run the copy file commands from the operating system

rem @&

exit;

2. 修改教本定义的变量

在运行教本中定义的一些变量，将其改为本地数据库安装环境的变量。

需要修改的变量有，

在close_Backup_run.bat脚本中：

set ORACLE_SID=TSTDB

set ORACLE_CONNECTSTRING=tstdb

set ORACLE_BASE=c：\oracle

set ORACLE_HOME=%ORACLE_BASE%\ora81

在close_backup.sql脚本中：

define adm = ‘sys’

define pwd = ‘oracle8i’

define dir = ‘C：\oracle\admin\TSTDB\backup’

define ctl = ‘&dir\control.ctl’

3. 执行数据库备份任务

在$ORACLE_BASE\admin\admin_script目录下运行open_Backup_run.bat

4. 执行自动备份

在windows系统中添加计划任务，定期运行open_Backup_run.bat
