oracle数据库备份与恢复 a piece of cake (4)(转)[@more@]

oracle数据库日志备份：（windows平台）

本片是接上次的数据库在线备份，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%insqlplus /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:oracleadminTSTDBackuparchive 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:oracleadminTSTDBackup'

define ctl = '&dircontrol.ctl'

3. 执行数据库备份任务

在$ORACLE_BASEadminadmin_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
