Oracle RMAN基础应用

RMAN备份必须在Oracle 的归档模式下才能进行
 查看数据库是否处于归档模式
 archive log list
 
更改数据库的归档模式
 shutdown immediate
 startup mount
 alter database archivelog;
 alter database open;
 
查看RMAN的备份环境
 rman target/
 show all;
 
启动控制文件自动备份
 configure controlfile autobackup on;
 show controlfile autobackup;
 
全库备份
 backup database;
 
查看备份信息
 list backup;
 list backup summary;
 
编写备份脚本
 0级全库备份脚本
 vi BackupFull.sh
 #Date 2014/4/6
 export ORACLE_SID=orcl
 export ORACLE_BASE=/u01/app/oracle
 export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
 export PATH=$PATH:$ORACLE_HOME/bin:
 rman target/ <<EOF_RMAN
 run{
 allocate channel c1 type disk;
 backup incremental level 0 tag 'db0' format 'u01/app/oracle/Backup/db0_%d_%T_%s' database
 include current controlfile;
 delete nopromp obsolete;
 release channel c1;
 }
 #end
 

1级增量备份
 vi Incr1.sh
 #Date 2014/4/6
 export ORACLE_SID=orcl
 export ORACLE_BASE=/u01/app/oracle
 export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
 export PATH=$PATH:$ORACLE_HOME/bin:
 rman target/ <<EOF_RMAN
 run{
 allocate channel c1 type disk;
 backup incremental level 1 tag 'db1' format 'u01/app/oracle/Backup/db0_%d_%T_%s' database
 include current controlfile;
 delete nopromp obsolete;
 release channel c1;
 }
 #end
 
chmod 755 BackupFull.sh
 chmod 755 Incr1.sh
 
自动执行备份脚本
 crontab –e
 
0 1 * * 0 /u01/app/oracle/Backup/BackupFull.sh
 >>/u01/app/oracle/Backup/BackupFull.log
 0 1 * * 3 /u01/app/oracle/Backup/BackupFull.sh
 >>/u01/app/oracle/Backup/BackupFull.log
 30 1 * * 1-2 /u01/app/oracle/Backup/Incr1.sh
 >>/u01/app/oracle/Backup/Incr1.log
 30 1 * * 4-6 /u01/app/oracle/Backup/Incr1.sh
 >>/u01/app/oracle/Backup/Incr1.log
 
Ps：周日和周三凌晨1点执行0级全库备份，其余天数1:30执行1级增量备份
 查看crontab
 crontab –l
