Windows Server系統定時任務備份ORACLE數據庫
一、編輯備份腳本
RMAN備份數據庫
1、在備份腳本目錄下，創建bat文件db_rman.bat
set ORACLE_SID=orcl1
D:\app\admin\product\11.2.0\dbhome_1\bin
rman target / cmdfile=D:/dbback/db_scripts/db_rman.txt log=D:/dbback/db_scripts/db_%date:~0,4%-%date:~5,2%-%date:~8,2%-%time:~0,2%-%time:~3,2%.log
FORFILES /P D:/dbback/db_scripts /M *.log /D -30 /C "cmd /c del @path"
exit
2、創建rman備份腳本db_rman.txt文件
sql 'alter session set nls_date_format="yyyy-mm-dd hh24:mi:ss"';
run {
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'D:/dbback/db_rman/%F.ctl';
backup tag 'dbfull' format 'D:/dbback/db_rman/full%u_%s_%p' database;
sql 'alter system archive log current';
backup archivelog all format 'D:/dbback/db_rman/arc_%T_%U.arg';
delete noprompt expired archivelog all;
delete noprompt archivelog all completed before 'sysdate-14';
delete noprompt obsolete;
delete noprompt expired backup;
}
list backup summary;
exit;
EXPDP備份數據庫
在備份腳本目錄下編輯定時任務db_expdp.bat
@echo off

REM 取當前系統時間,可能因操作系統不同而取值不一樣
set CURDATE=%date:~0,4%%date:~5,2%%date:~8,2%
set CURMON=%date:~0,4%%date:~5,2%
set CURTIME=%time:~0,2%
REM 小時數如果小於10，則在前面補0
if "%CURTIME%"==" 0" set CURTIME=00
if "%CURTIME%"==" 1" set CURTIME=01
if "%CURTIME%"==" 2" set CURTIME=02
if "%CURTIME%"==" 3" set CURTIME=03
if "%CURTIME%"==" 4" set CURTIME=04
if "%CURTIME%"==" 5" set CURTIME=05

if "%CURTIME%"==" 8" set CURTIME=08
if "%CURTIME%"==" 9" set CURTIME=09
set CURTIME=%CURTIME%%time:~3,2%%time:~6,2%
REM 設置所有者、用戶名和密碼
set OWNER=orcl
set USER=dba
set PASSWORD=manager
REM 創建備份用目錄，目錄結構為F:\expdpbak
set FILENAME=%OWNER%_%CURDATE%_%CURTIME%.dmp
set EXPLOG=%OWNER%_%CURDATE%_%CURTIME%.log
expdp %USER%/%PASSWORD%@%OWNER% DIRECTORY=DUMP_DIR DUMPFILE=%FILENAME% LOGFILE=%EXPLOG%
FORFILES /P F:\expdpbak /M *.dmp /D -30 /C "cmd /c del @path"
FORFILES /P F:\expdpbak /M *.log /D -30 /C "cmd /c del @path"
exit
EXP/IMP備份數據庫
set filename=d:/db_backup/db_expdp/scott_%date:~0,4%%date:~5,2%%date:~8,2%
exp scott/tiger file=%filename%.dmp log=%filename%.log
FORFILES /P D:\db_backup\db_expdp /M *.dmp /D -15 /C "cmd /c del @path"
FORFILES /P D:\db_backup\db_expdp /M *.log /D -15 /C "cmd /c del @path"
exit
二、編輯定時任務（RMAN備份數據庫）
創建任務，輸入定時任務名稱
新建觸發器，設置每天23:30:00開始任務
新建操作，選定備份定時任務腳本.bat
條件選項，默認
設置選項，設定任務運行時間超過以下時間，即12小時，停止任務
windows下expdp腳本
#FORFILES /P E:\bak /M *.dmp /D -2 /C "cmd /c del @path"
#刪除E:\bak目錄下.dmp結尾的3天前的文件
set ORACLE_SID=orcl
set dumpfile=dmp%date:~0,4%%date:~5,2%%date:~8,2%%%U.dmp
set logfile=dmp%date:~0,4%%date:~5,2%%date:~8,2%.log
set syncfile=dmp%date:~0,4%%date:~5,2%%date:~8,2%
set insert_head=insert into BACK_USER.sync_file_list (db_ip,INCREMENTAL_LEVEL,file_name,pwd_name,handle,back_completion_time,sync_status) values('10.86.240.10','0',
