oracle rman备份脚本学习

无论在什么系统下，运用数据库都是必不可少的。今天我就来跟大家探讨一下oracle rman备份脚本学习。 查询字符集 SQL> select * from nls_database_parameters; NLS_CHARACTERSET AL32UTF8   备份时字符集很重要，不然会出乱码 一、0级备份（全备）红色是要修改的，根据个人的存放位置。 [oracle@oracle122 script]$ cat db_bak0.rman  run {     configure retention policy to recovery window of 8 days;     configure controlfile autobackup on;     configure controlfile autobackup format for device type disk to '/home/oracle/rmanbak/%F';     allocate channel ch1 device type disk format '/home/oracle/rmanbak/inc0_%d_%s_%p_%u_%T';     backup incremental level 0 tag='level 0' database skip inaccessible filesperset 10 plus archivelog filesperset 20;     release channel ch1; } allocate channel for maintenance device type disk; crosscheck backup; delete noprompt expired backup; delete noprompt obsolete; delete noprompt archivelog until time 'sysdate-30'; 0级运行脚本 [oracle@oracle122 script]$ cat exec_0_level.sh  ORACLE_HOSTNAME=oracle122; export ORACLE_HOSTNAME ORACLE_BASE=/u01/app; export ORACLE_BASE ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1; export ORACLE_HOME ORACLE_SID=orcl; export ORACLE_SID ORACLE_TERM=xterm; export ORACLE_TERM PATH=/usr/sbinPATH; export PATH PATH=$ORACLE_HOME/binPATH; export PATH export DATE=$(date +%Y_%m_%d) export NLS_LANG="Simplified Chinese_china".AL32UTF8 /u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/sys_admin cmdfile /home/oracle/rmanbak/script/db_bak0.rman log/home/oracle/rmanbak/script/log/rman_$DATE.log append 二、1级备份（增量） [oracle@oracle122 script]$ cat db_bak1.rman  run {     configure retention policy to recovery window of 8 days;     configure controlfile autobackup on;     configure controlfile autobackup format for device type disk to '/home/oracle/rmanbak/%F';     allocate channel ch1 device type disk format '/home/oracle/rmanbak/inc1_%d_%s_%p_%u_%T';     backup incremental level 1 tag='level 1' database skip inaccessible filesperset 10 plus archivelog filesperset 20;     release channel ch1; } allocate channel for maintenance device type disk; crosscheck backup; delete noprompt expired backup; delete noprompt obsolete; delete noprompt archivelog until time 'sysdate-30'; 1级运行脚本 [oracle@oracle122 script]$ cat exec_1_level.sh  ORACLE_HOSTNAME=oracle122; export ORACLE_HOSTNAME ORACLE_BASE=/u01/app; export ORACLE_BASE ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1; export ORACLE_HOME ORACLE_SID=orcl; export ORACLE_SID ORACLE_TERM=xterm; export ORACLE_TERM PATH=/usr/sbinPATH; export PATH PATH=$ORACLE_HOME/binPATH; export PATH export DATE=$(date +%Y_%m_%d) export NLS_LANG="Simplified Chinese_china".AL32UTF8 /u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/sys_admin cmdfile /home/oracle/rmanbak/script/db_bak1.rman log/home/oracle/rmanbak/script/log/rman_$DATE.log append 三、2级备份（从0级追加到现在的备份） [oracle@oracle122 script]$ cat db_bak2.rman  run {     configure retention policy to recovery window of 8 days;     configure controlfile autobackup on;     configure controlfile autobackup format for device type disk to '/home/oracle/rmanbak/%F';     allocate channel ch1 device type disk format '/home/oracle/rmanbak/inc2_%d_%s_%p_%u_%T';     backup incremental level 2 tag='level 2' database skip inaccessible filesperset 10 plus archivelog filesperset 20 delete all input;     release channel ch1; } allocate channel for maintenance device type disk; crosscheck backup; delete noprompt expired backup; delete noprompt obsolete; 2级运行脚本 [oracle@oracle122 script]$ cat exec_2_level.sh  ORACLE_HOSTNAME=oracle122; export ORACLE_HOSTNAME ORACLE_BASE=/u01/app; export ORACLE_BASE ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1; export ORACLE_HOME ORACLE_SID=orcl; export ORACLE_SID ORACLE_TERM=xterm; export ORACLE_TERM PATH=/usr/sbinPATH; export PATH PATH=$ORACLE_HOME/binPATH; export PATH export DATE=$(date +%Y_%m_%d) export NLS_LANG="Simplified Chinese_china".AL32UTF8 /u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/sys_admin cmdfile /home/oracle/rmanbak/script/db_bak2.rman log/home/oracle/rmanbak/script/log/rman_$DATE.log append 定时备份星期天为0级全备，星期三为2级备份，星期一，星期二，星期四，星期五，星期六为1级增量备份晚上11点开始备份 [oracle@oracle122 script]$ crontab -l * 23 * *  0 /home/oracle/rmanbak/script/exec_0_level.sh  * 23 * *  1 /home/oracle/rmanbak/script/exec_1_level.sh  * 23 * *  2 /home/oracle/rmanbak/script/exec_1_level.sh  * 23 * *  3 /home/oracle/rmanbak/script/exec_2_level.sh  * 23 * *  4 /home/oracle/rmanbak/script/exec_1_level.sh  * 23 * *  5 /home/oracle/rmanbak/script/exec_1_level.sh  * 23 * *  6 /home/oracle/rmanbak/script/exec_1_level.sh 如果想深入体验LINUX系统的新手，也可以先下载一个方德Linux软件中心试用一下。 免费下载地址：http://www.nfs-cloud.cn:81/appCenter/open/softcenter
