1.rman完全恢复的前提条件：历史的datafile,controlfile和spfile备份，加上完整的archivelog和完好的redolog。
2.rman备份脚本：
a.RMAN 0级备份命令:
run{ allocate channel c1 type disk; allocate channel c2 type disk; allocate channel c3 type disk; backup incremental level0 tag'level0' format"E:\recovery_area\rfdb\rfdb\AUTOBACKUP\rman_dir\RFDB_level_0_%u_%s_%p"ascompressed backupsetdatabase; sql"alter system archive log current"; backup filesperset3 format"E:\recovery_area\rfdb\rfdb\AUTOBACKUP\rman_dir\arch_%u_%s_%p_%c"
archivelog all delete input; #备份归档可选，可以单独定期备份
release channel c1;
release channel c2;
release channel c3;
}
b.RMAN 1级备份命令:
run{ allocate channel c1 type disk; allocate channel c2 type disk; allocate channel c3 type disk; backup incremental level1 tag'level1' format'E:\recovery_area\rfdb\rfdb\AUTOBACKUP\rman_dir\RFDB_level_1_%u_%s_%p'ascompressed backupsetdatabase; sql'alter system archive log current'; backup filesperset3 format'E:\recovery_area\rfdb\rfdb\AUTOBACKUP\rman_dir\arch_%u_%s_%p'
archivelog all delete input; #备份归档可选，可以单独定期备份
release channel c1;
release channel c2;
release channel c3;
}
c.rman删除备份命令（在保留最近一天备份的情况下，删除其他备份）:
DELETE NOPROMPT OBSOLETE RECOVERY WINDOW OF1 DAYS;
d.操作系统层面运行rman备份或删除命令(windows/linux)：
rman target sys/rf4rfvbgt56yhn@rfdb nocatalog CMDFILE'D:\app\rman\rman_file\level_0.txt' log=E:\recovery_area\rfdb\rfdb\AUTOBACKUP\rman_dir\log\rman_level_0.log
export ORACLE_BASE=/u01/app/oracleexport ORACLE_HOME=/u01/app/oracle/product/11.2.0/db1export ORACLE_SID=atestexport PATH=$ORACLE_HOME/bin:$PATHrman target sys/123456@atest nocatalog CMDFILE'/u01/rman/rman.sh' log=/u01/rman/rman.log
0002 * *1 bash /u01/rman_file/run_rman_0.sh0002 * *3 bash /u01/rman_file/run_rman_0.sh0002 * *5 bash /u01/rman_file/run_rman_0.sh0004 * * * bash /u01/rman_file/run_delete.sh3411 * * * bash /u01/rman_file/run_rman_0.sh
e.rman参数设置：
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
RMAN>CONFIGURE DEFAULT DEVICE TYPE TO DISK;RMAN> CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE disk TO2;RMAN> CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE disk TO2;
3.rman恢复
a.拷贝datafile,controlfile和spfile的rman备份，以及完整的archivelog和完好的redolog文件到新的数据库。
b.切换至oracle用户，进入rman（先设置sid）：
export ORACLE_SID=rfdb
rlwrap rman target /
c.启动一个伪实例：
RMAN>startup nomountconnected to target database (not started)startup failed: ORA-01078: failureinprocessing system parametersLRM-00109: could not open parameter file'/u01/app/oracle/product/11.2.0/db1/dbs/initrfdb.ora'starting Oracle instance without parameter fileforretrieval of spfileOracle instance startedTotal System Global Area1068937216bytesFixed Size2260088bytesVariable Size281019272bytesDatabase Buffers780140544bytesRedo Buffers5517312 bytes
d.在伪实例下恢复spfile文件（必须要指定rman的备份片）：
RMAN> restore spfilefrom"/u01/ora_bak/ora_bak/autobackup/2015_12_07/o1_mf_s_897845728_c6bnq1rq_.bkp";Starting restore at14-DEC-15usingchannel ORA_DISK_1channel ORA_DISK_1: restoring spfilefrom AUTOBACKUP /u01/ora_bak/ora_bak/autobackup/2015_12_07/o1_mf_s_897845728_c6bnq1rq_.bkpchannel ORA_DISK_1: SPFILE restorefromAUTOBACKUP completeFinished restore at14-DEC-15
e.关闭伪实例，用spfile文件启动至nomount状态：
RMAN>shutdown abortOracle instance shut downRMAN>startup nomountconnected to target database (not started)Oracle instance startedTotal System Global Area1068937216bytesFixed Size2260088bytesVariable Size910164872bytesDatabase Buffers150994944bytesRedo Buffers5517312 bytes
f.恢复控制文件（必须要指定rman的备份片，备份片应该和spfile的恢复片是同一个）：
RMAN> restore controlfilefrom"/u01/ora_bak/ora_bak/autobackup/2015_12_07/o1_mf_s_897845728_c6bnq1rq_.bkp";Starting restore at14-DEC-15allocated channel: ORA_DISK_1channel ORA_DISK_1: SID=1146 device type=DISKchannel ORA_DISK_1: restoring control filechannel ORA_DISK_1: restore complete, elapsed time:00:00:01output file name=/u01/app/oracle/oradata/ATEST/controlfile/o1_mf_c5fr9b0h_.ctloutput file name=/u01/app/oracle/fast_recovery_area/ATEST/controlfile/o1_mf_c5fr9b6n_.ctlFinished restore at14-DEC-15
g.启动数据库至mount状态：
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
h.把拷贝到新机器的备份文件注册到（刚恢复的）控制文件中（redolog不能被注册，所以最后有报错，没有关系）：
RMAN> catalog start with"/u01/ora_bak";Startingimplicit crosscheck backup at14-DEC-15allocated channel: ORA_DISK_1channel ORA_DISK_1: SID=1146 device type=DISKCrosschecked1objectsFinishedimplicit

k.以resetlogs打开数据库（在此之前，先删除原来的redolog，因为数据库会重新创建一组redolog）：
删除原来的redo：
rm -rf /u01/app/oracle/oradata/ATEST/onlinelog/*
以resetlogs打开数据库：
RMAN>alter database open resetlogs;using target database control file instead of recovery catalog
database opened
至此，数据库恢复全部完成！
