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 manipulate 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
