oracle rman备份

rman  登录到cmd

打开cmd 输入 rmanconnect target jhpt/1@orcl

C:\Documents and Settings\Administrator>rman catalog tangtang/lenovoE520 target system/lenovoE520@tang
RMAN>show all;
设置控制文件的自动备份和自动备份的目录（建议设置，备份目录自定）
RMAN>CONFIGURE CONTROLFILE AUTOBACKUP ON;
RMAN>CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'F:\backup\%F';
RMAN>exit;
按如上设置后，控制文件和spfile就会随着数据库备份自动备份到d:/backup下；建立脚本文件和批处理文件：
脚本文件，如文件名为orabackup.rcv，具体内容如下：
run {
allocate channel d1 type disk;
allocate channel d2 type disk;
backup incremental level 0 database format 'F:\backup\level0_%d_%s_%p_%u.bak';
sql 'alter system archive log current';
backup archivelog all format 'F:\backup\log_%d_%s_%p_%u.bak' delete all input;
release channel d2;
release channel d1;
}
crosscheck backup;
delete noprompt expired backup;
delete noprompt obsolete;
resync catalog;
exit批处理文件，如文件名为orabackup.bat，具体内容如下
rman catalog rmanuser1/rmanuser1@orada target system/system@oradb CMDFILE 'F：\backup\orabackup.rcv' LOG ’F:\backup\oracl_%date'将orabackup.bat和orabackup.rcv存放在同一目录下，执行orabackup.bat就可以调用orabackup.rcv备份数据库了，你可以再windows的计划任务里执行orabackup.bat就可以自动备份了；编写自动处理脚本及dos批处理文件进行rman备份1）确定备份策略及配置，编写rman备份脚本，保存至E:\rman_bak\rman_scr.sql脚本代码：run{configure retention policy to recovery window of 7 days;configure controlfile autobackup on;configure controlfile autobackup format for device type disk to 'F:\backup\%F';allocate channel ch1 device type disk format 'F:\backup\%U';backup database skip inaccessible filesperset 10plus archivelog filesperset 20delete all input;release channel ch1;}allocate channel for maintenance device type disk;crosscheck backupset;delete noprompt obsolete;2）编写dos批处理脚本 rman_src.batrman target / cmdfile='F:\backup\rman_scr.sql'>> F:\backup\log.txt3）执行可手工执行rman_src.bat进行备份；或通过控制面板-> 任务计划中添加计划

WINDOWS 上做的RMAN.sql内容如下：run{configure retention policy to recovery window of 7 days;configure controlfile autobackup on;configure controlfile autobackup format for device type disk to 'c:\backupb\%F_%T';allocate channel ch1 device type disk format 'C:\backupb\%T';backup database skip inaccessible filesperset 10plus archivelog filesperset 20delete all input;release channel ch1;}allocate channel for maintenance device type disk;crosscheck backupset;delete noprompt obsolete;11.bat (批处理文件)rman target / cmdfile='c:\backupb\rman.sql'>> c:\backupb\log.txt；简单的注释run{configure retention policy to recovery window of 7 days;configure controlfile autobackup on;--控制文件的自动备份configure controlfile autobackup format for device type disk to 'c:\backup\%F'; --控制文件目录allocate channel ch1 device type disk format 'c:\backup\%U'; --备份集的目录backup database skip inaccessible filesperset 10 --生成10个备份集plus archivelog filesperset 20delete all input;release channel ch1; --释放备份通道}allocate channel for maintenance device type disk;crosscheck backupset;delete noprompt obsolete; --删除未找到已废弃的备份（根据备份策略 目前的策略是保存最近7天的）在本机器上还原RMAN> shutdown immediateRMAN> startup mount;RMAN>restore database; --还原 指物理意义的文件的还原RMAN>recover database;--恢复 让数据一致最后打开数据库RMAN> alter database open--还原某一个时期的备份run{

restore database;
recover database;}
