Rman归档模式下的热备份策略及实施方案一、归档模式设置：1.查看归档状态为非归档SQL select log_mode from v$database;LOG_MODE------------NOARCHIVELOGarchive状态DisabledSQL archive log listDatabase log mode No Archive ModeAutomatic archival DisabledArchive destination /archivelogOldest online log sequence 2Current log sequence 42.设置数据库为归档模式SQL shutdown immediate；SQL startup mount;SQL alter database archivelog;SQL alter system set log_archive_start=true scope=spfile;SQL shutdown immediate;SQL startup;SQL archive log listDatabase log mode Archive ModeAutomatic archival EnabledArchive destination /archivelogOldest online log sequence 2Next log sequence to archive 4Current log sequence 4二、rman配置准备：在Rman中，已设置了参数每次备份自动备份控制文件和参数文件,其配置命令为：　 $ rman target / RMAN CONFIGURE CONTROLFILE AUTOBACKUP ON; --设置控制文件和参数文件自动备份　 RMAN set controlfileautobackup format for device type disk to /backupora/%F; 　--设置自动备份控制文件存放位置三、备份策略：　1、每三个月使用磁带机进行一次数据库全备份:crontab内容为：--每个季度的第一天早上1点作一次全备份，将备份记录输出到full_backup.log文件0 1 1 1,4,7,10 * oracle /backupora/full_backup.sh /backupora/full_backup.log## full_backup.sh内容如下：ORACLE_HOME=/orac/orahome/10.2.0/db_1;export ORACLE_HOMEORACLE_SID=hisu; export ORACLE_SIDPATH=$PATH:ORACLE_HOME/bin;export PATHdaterman /backupora/full_backup.sqldate##full_backup.sql内容：$rman target /run {allocate channel c1 type disk;allocate channel c2 type disk;allocate channel c3 type disk;allocate channel c4 type disk;backup database;backuparchivelog all not backed up;copy current controlfile to /backupora/control.ctl;release channel c4;release channel c3;release channel c2;release channel c1;}2、每星期进行一次level 0的增量备份（基础备份）：crontab内容为：--每个星期五23:00分作一次基本备份，将备份记录输出到inc_backup_lv0.log文件0 23 * * 5 oracle /backupora/inc_backup_lv0.sh /backupora/inc_backup_lv0.log## inc_backup_lv0.sh内容如下：ORACLE_HOME=/orac/orahome/10.2.0/db_1;export ORACLE_HOMEORACLE_SID=hisu; export ORACLE_SIDPATH=$PATH:ORACLE_
