参考技术AOracle数据库RMAN的自动备份脚本简介
各位同学知道Oracle数据库RMAN如何自动备份脚本嘛?下面我为大家整理了关于Oracle数据库RMAN的自动备份脚本文章,希望能为你提供帮助:
1、数据库设置为归档方式
2、数据库的备份脚本
db_full_backup.sh :数据库全备脚本
db_l0_backup.sh :数据库0级备份脚本
db_l1_backup.sh :数据库1级备份脚本
ftp.sh :数据FTP上传脚本
ftp_del.sh :数据FTP清理脚本
rman_bak.sh :数据备份主程序
3、备份原理
每周1、3、6进行0级备份
每周日、2、4、5进行1级备份
备份文件上传到FTP服务器
FTP服务器每周清理一次,但是清理后将周六和周日的备份进行保留(6.bak和0.bak)
所有工作防暑crontab中自动执行备份
4、备份目录含义
arc :数据库归档目录
rmanbak :数据库备份文件的保存目录
rmanscripts :数据库脚本存放路径
5、FTP目录
ftp上必须手动建立目录
L0:
---1
---3
---6
---6.bak
L1:
---2
---4
---5
---0
---0.bak
rman_bak.sh脚本主程序

Oracle 自动化备份脚本
Oracle 日常RMAN备份脚本,很基础。但是对于多个需要备份的Oracle数据库,可以很简单实施,并利于后期批量状态的查询。
-
备份脚本,基于linux,windows环境需要适当修改。
主脚本,会调用2,3步骤的rman.sql&status.sql$ more main.sh #set env #########################Change the below parameter for the different server################## export host_ip=172.16.32.115 export instance_name=liang export username=liang export password=liang export syspsw=oracle export backup_home=/home/oracle/bk export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_1 export PATH=$PATH:$ORACLE_HOME/db_1/bin:/sbin:/usr/sbin ##################################################################################### export curTime=$(date "+%Y%m%d") mkdir $backup_home/ftp/$curTime echo "-----------------------------RMAN start-----------------------------";date #backup start cd $backup_home $ORACLE_HOME/bin/rman target sys/[email protected]$host_ip:1521/$instance_name cmdfile=‘rman.sql‘ echo "------------------------------RMAN End------------------------------";date sleep 10 echo "------------------------------SQL Start------------------------------";date $ORACLE_HOME/bin/sqlplus $username/[email protected]$host_ip:1521/$instance_name @status.sql echo "------------------------------END-----------------------------";date

RMAN备份sql脚本
[[email protected] bk]$ more rman.sql run { ALLOCATE CHANNEL node_c1 DEVICE TYPE DISK MAXPIECESIZE=5G; ALLOCATE CHANNEL node_c2 DEVICE TYPE DISK MAXPIECESIZE=5G; backup as compressed backupset database format ‘C:ftpuploadfiledb_%U.bak_%T‘; sql ‘alter system switch logfile‘; CROSSCHECK ARCHIVELOG ALL; backup as compressed backupset archivelog all format ‘C:ftpuploadfilearchivelog_%d_%s_%p_%T‘ not backed up 2 times; backup spfile format ‘C:ftpuploadfilespfile_%U_%T‘; backup current controlfile format ‘C:ftpuploadfilecontrolfile_%d_%s_%p_%I_%u_%T‘; sql ‘alter system switch logfile‘; CROSSCHECK BACKUP; CROSSCHECK COPY; delete noprompt archivelog all completed before ‘sysdate-7‘; release channel node_c1; release channel node_c2; }
- 查询备份状态的脚本,并将查询信息打印到日志,方便查询。
