1，开始备份

备份脚本rman_full_backup.sh内容如下：

#!/bin/shexport DATE=`date +%F`export BACK_DIR='/backupdisk/backup/data'su - oracle -c "mkdir -p $BACK_DIR/$DATErman log=$BACK_DIR/$DATE/rman_backup.log target / <<EOFrun{        backup as compressed backupset database                format '$BACK_DIR/$DATE/full_%d_%T_%s.bak'        plus archivelog                 format '$BACK_DIR/$DATE/arch_%d_%T_%s.bak' delete input;        sql 'alter system archive log current';}crosscheck backup;crosscheck archivelog all;delete noprompt expired backup;delete noprompt expired archivelog all;delete noprompt obsolete;exitEOF"su - oracle -c "chmod 775 $BACK_DIR/$DATE/*"#cd /home/pdbcakup/echo "begin to copy the backup to pd servers." >>  /tmp/oracle_fullback.log#cp -r $BACK_DIR/$DATE /home/pdbcakupecho "end to copy the backup to pd server." >>  /tmp/oracle_fullback.log

备份过程如下所示：

[root@test_90 ~]# bash -x /oracle/backup/scripts/rman_full_backup.sh++ date +%F+ export DATE=2016-03-17+ DATE=2016-03-17+ export BACK_DIR=/oracle/backup/data+ BACK_DIR=/oracle/backup/data+ su - oracle -c 'mkdir -p /oracle/backup/data/2016-03-17rman log=/oracle/backup/data/2016-03-17/rman_backup.log target / <<EOFrun{        backup as compressed backupset database                format '\''/oracle/backup/data/2016-03-17/full_%d_%T_%s.bak'\''        plus archivelog                 format '\''/oracle/backup/data/2016-03-17/arch_%d_%T_%s.bak'\'' delete input;        sql '\''alter system archive log current'\'';}crosscheck backup;crosscheck archivelog all;delete noprompt expired backup;delete noprompt expired archivelog all;delete noprompt obsolete;exitEOF'RMAN> 2> 3> 4> 5> 6> 7> RMAN> RMAN> RMAN> RMAN> RMAN> RMAN> + su - oracle -c 'chmod 775 /oracle/backup/data/2016-03-17/*'+ echo 'begin to copy the backup to pd servers.'+ echo 'end to copy the backup to pd server.'[root@test_90 ~]# ll

2，查看备份的文件目录

3，传输

[oracle@test_90 ~]$ scp -P50390 -r /oracle/pfile_20160317.ora 2016-03-17 192.168.237.46:/oracle/backup/The authenticity of host '[192.168.237.46]:50390 ([192.168.237.46]:50390)' can't be established.RSA key fingerprint is c0:1c:30:8a:bd:8c:90:b2:af:57:1d:29:ab:1f:90:f9.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added '[192.168.237.46]:50390' (RSA) to the list of known hosts.oracle@192.168.237.46's password: pfile_20160317.ora                                                                                                                                           100% 1008     1.0KB/s   00:00    [oracle@test_90 ~]$ [oracle@test_90 data]$ scp -P50390 -r 2016-03-17  192.168.237.46:/oracle/backup/oracle@192.168.237.46's password: full_POWERDES_20160317_14.bak                                                                                                                                100% 1914MB   4.7MB/s   06:49    full_POWERDES_20160317_15.bak                                                                                                                                100% 1088KB   1.1MB/s   00:00    arch_POWERDES_20160317_16.bak                                                                                                                                100%  180KB 179.5KB/s   00:00    rman_backup.log                                                                                                                                              100% 6331     6.2KB/s   00:00    [oracle@test_90 data]$

4，去目标库上nomount方式启动数据库

SQL> shutdown immediateORA-01507: database not mountedORACLE instance shut down.SQL> startup nomount pfile='/oracle/backup/pfile_20160317.ora';ORACLE instance started.Total System Global Area 1603411968 bytesFixed Size    2213776 bytesVariable Size 1023412336 bytesDatabase Buffers  570425344 bytesRedo Buffers    7360512 bytesSQL>

5，恢复控制文件

RMAN> restore controlfile to '/oracle/app/oracle/orclstu/control01.ctl' from '/oracle/backup/2016-03-17/full_POWERDES_20160317_15.bak';Starting restore at 17-MAR-16using channel ORA_DISK_1channel ORA_DISK_1: restoring control filechannel ORA_DISK_1: restore complete, elapsed time: 00:00:01Finished restore at 17-MAR-16RMAN>

6，将数据库状态改成mount：

RMAN> alter database mount2> ;database mountedreleased channel: ORA_DISK_1RMAN>

7，注册备份文件

RMAN> catalog start with '/oracle/backup/2016-03-17';Starting implicit crosscheck backup at 17-MAR-16allocated channel: ORA_DISK_1channel ORA_DISK_1: SID=134 device type=DISKCrosschecked 4 objectsFinished implicit crosscheck backup at 17-MAR-16Starting implicit crosscheck copy at 17-MAR-16using channel ORA_DISK_1Finished implicit crosscheck copy at 17-MAR-16searching for all files in the recovery areacataloging files...no files catalogedsearching for all files that match the pattern /oracle/backup/2016-03-17List of Files Unknown to the Database=====================================File Name: /oracle/backup/2016-03-17/rman_backup.logFile Name: /oracle/backup/2016-03-17/arch_POWERDES_20160317_16.bakFile Name: /oracle/backup/2016-03-17/full_POWERDES_20160317_15.bakFile Name: /oracle/backup/2016-03-17/full_POWERDES_20160317_14.bakDo you really want to catalog the above files (enter YES or NO)?

8，开始执行restore恢复操作，将数据从备份集写入到磁盘上的数据文件里面，还原已经备份的数据文件

RMAN> restore database;Starting restore at 17-MAR-16using target database control file instead of recovery catalogallocated channel: ORA_DISK_1channel ORA_DISK_1: SID=133 device type=DISKchannel ORA_DISK_1: starting datafile backup set restorechannel ORA_DISK_1: specifying datafile(s) to restore from backup setchannel ORA_DISK_1: restoring datafile 00001 to /data/oracle/orclstu/system01.dbfchannel ORA_DISK_1: restoring datafile 00002 to /data/oracle/orclstu/sysaux01.dbfchannel ORA_DISK_1: restoring datafile 00003 to /data/oracle/orclstu/undotbs01.dbfchannel ORA_DISK_1: restoring datafile 00004 to /data/oracle/orclstu/users01.dbfchannel ORA_DISK_1: restoring datafile 00005 to /data/oracle/orclstu/orclstuk01.dbfchannel ORA_DISK_1: restoring datafile 00006 to /data/oracle/orclstu/plas01.dbfchannel ORA_DISK_1: restoring datafile 00007 to /data/oracle/orclstu/plcrm01.dbfchannel ORA_DISK_1: restoring datafile 00008 to /data/oracle/orclstu/pl01.dbfchannel ORA_DISK_1: restoring datafile 00009 to /data/oracle/orclstu/help01.dbfchannel ORA_DISK_1: reading from backup piece /oracle/backup/2016-03-17/full_POWERDES_20160317_14.bakchannel ORA_DISK_1: piece handle=/oracle/backup/2016-03-17/full_POWERDES_20160317_14.bak tag=TAG20160317T202130channel ORA_DISK_1: restored backup piece 1channel ORA_DISK_1: restore complete, elapsed time: 00:14:25Finished restore at 17-MAR-16RMAN>

9，应用归档日志恢复数据文件

RMAN> recover database;Starting recover at 17-MAR-16using channel ORA_DISK_1starting media recoverychannel ORA_DISK_1: starting archived log restore to default destinationchannel ORA_DISK_1: restoring archived logarchived log thread=1 sequence=1428channel ORA_DISK_1: reading from backup piece /oracle/backup/2016-03-17/arch_POWERDES_20160317_16.bakchannel ORA_DISK_1: piece handle=/oracle/backup/2016-03-17/arch_POWERDES_20160317_16.bak tag=TAG20160317T202918channel ORA_DISK_1: restored backup piece 1channel ORA_DISK_1: restore complete, elapsed time: 00:00:03archived log file name=/oracle/app/oracle/flash_recovery_area/POWERDES/archivelog/2016_03_17/o1_mf_1_1428_cgog3ons_.arc thread=1 sequence=1428channel default: deleting archived log(s)archived log file name=/oracle/app/oracle/flash_recovery_area/POWERDES/archivelog/2016_03_17/o1_mf_1_1428_cgog3ons_.arc RECID=2 STAMP=906760822unable to find archived logarchived log thread=1 sequence=1429RMAN-00571: ===========================================================RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============RMAN-00571: ===========================================================RMAN-03002: failure of recover command at 03/17/2016 22:00:29RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 1429 and starting SCN of 31576222RMAN>

需要将缺失的归档日志从原始备份库copy到微软云azure的oracle服务器上，或者直接恢复到SCN点上:

RMAN> recover database until scn 31576222;Starting recover at 17-MAR-16using channel ORA_DISK_1starting media recoverymedia recovery complete, elapsed time: 00:00:00Finished recover at 17-MAR-16RMAN>

10，打开数据库

RMAN> alter database open resetlogs;database openedRMAN>

11，验证数据库
