Oracle數(shù)據(jù)庫日志備份：（windows平臺） 本片是接上次的數(shù)據(jù)庫在線備份，進行數(shù)據(jù)庫全備份后需要備份歸檔的日志文件。 1. 建立數(shù)據(jù)庫備份的腳本 在上面建立的目錄下建立如下的兩個腳本。 1.1 建立執(zhí)行備份任務(wù)的腳本(批處理文件） 文件內(nèi)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 建立完成備份認為的命令文件(sqlplus內(nèi)執(zhí)行的sql腳本） 文件內(nèi)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$archived_log
WHERE completion_time >= trunc(sysdate)-1
AND completion_time < trunc(sysdate); prompt spool off;;
spool off; Rem Run the copy file commands from the Operating system
rem @&
exit; 2. 修改教本定義的變量
在運行教本中定義的一些變量，將其改為本地數(shù)據(jù)庫安裝環(huán)境的變量。
需要修改的變量有,
在close_Backup_run.bat腳本中：
set ORACLE_SID=TSTDB
set ORACLE_CONNECTSTRING=tstdb
set ORACLE_BASE=c:/oracle
set ORACLE_HOME=%ORACLE_BASE%/ora81
在close_backup.sql腳本中：
define adm = 'sys'
define pwd = 'oracle8i'
define dir = 'C:/oracle/admin/TSTDB/backup'
define ctl = '&dir/control.ctl' 3. 執(zhí)行數(shù)據(jù)庫備份任務(wù) 在$ORACLE_BASE/admin/admin_script目錄下運行open_Backup_run.bat 4. 執(zhí)行自動備份 在windows系統(tǒng)中添加計劃任務(wù)，定期運行open_Backup_run.bat
