oracle11g 在azure云中使用rman进行实例迁移
1，開始备份
备份脚本rman_full_backup.sh内容例如以下：
#!/bin/sh
export DATE=`date +%F`
export BACK_DIR=‘/backupdisk/backup/data‘
su - oracle -c "
mkdir -p $BACK_DIR/$DATE
rman log=$BACK_DIR/$DATE/rman_backup.log target / <<EOF
run{
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;
exit
EOF
"
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/pdbcakup
echo "end to copy the backup to pd server." >> /tmp/oracle_fullback.log
备份步骤例如以下所看到的：
[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/2016-03-17
rman log=/oracle/backup/data/2016-03-17/rman_backup.log target / <<EOF
run{
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;
exit
EOF
‘
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 ~]# ll2，查看备份的文件文件夹
RMAN> list backup of controlfile;

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.

4，去目标库上nomount方式启动数据库
SQL> shutdown immediate ORA-01507: database not mounted ORACLE instance shut down. SQL> startup nomount pfile=‘/oracle/backup/pfile_20160317.ora‘; ORACLE instance started. Total System Global Area 1603411968 bytes Fixed Size 2213776 bytes Variable Size 1023412336 bytes Database Buffers 570425344 bytes Redo Buffers 7360512 bytes SQL>
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-16 using channel ORA_DISK_1 channel ORA_DISK_1: restoring control file channel ORA_DISK_1: restore complete, elapsed time: 00:00:01 Finished restore at 17-MAR-16 RMAN>
6，将数据库状态改成mount：
RMAN> alter database mount 2> ; database mounted released channel: ORA_DISK_1 RMAN>
7，注冊备份文件
RMAN> catalog start with ‘/oracle/backup/2016-03-17‘; Starting implicit crosscheck backup at 17-MAR-16 allocated channel: ORA_DISK_1 channel ORA_DISK_1: SID=134 device type=DISK Crosschecked 4 objects Finished implicit crosscheck backup at 17-MAR-16 Starting implicit crosscheck copy at 17-MAR-16 using channel ORA_DISK_1 Finished implicit crosscheck copy at 17-MAR-16 searching for all files in the recovery area cataloging files... no files cataloged searching for all files that match the pattern /oracle/backup/2016-03-17 List of Files Unknown to the Database ===================================== File Name: /oracle/backup/2016-03-17/rman_backup.log File Name: /oracle/backup/2016-03-17/arch_POWERDES_20160317_16.bak File Name: /oracle/backup/2016-03-17/full_POWERDES_20160317_15.bak File Name: /oracle/backup/2016-03-17/full_POWERDES_20160317_14.bak Do you really want to catalog the above files (enter YES or NO)? YES cataloging files... cataloging done List of Cataloged Files ======================= File Name: /oracle/backup/2016-03-17/arch_POWERDES_20160317_16.bak File Name: /oracle/backup/2016-03-17/full_POWERDES_20160317_15.bak File Name: /oracle/backup/2016-03-17/full_POWERDES_20160317_14.bak List of Files Which Where Not Cataloged ======================================= File Name: /oracle/backup/2016-03-17/rman_backup.log RMAN-07517: Reason: The file header is corrupted RMAN>
8。開始运行restore恢复操作。将数据从备份集写入到磁盘上的数据文件中面，还原已经备份的数据文件
RMAN> restore database; Starting restore at 17-MAR-16 using target database control file instead of recovery catalog allocated channel: ORA_DISK_1 channel ORA_DISK_1: SID=133 device type=DISK channel ORA_DISK_1: starting datafile backup set restore channel ORA_DISK_1: specifying datafile(s) to restore from backup set channel ORA_DISK_1: restoring datafile 00001 to /data/oracle/orclstu/system01.dbf channel ORA_DISK_1: restoring datafile 00002 to /data/oracle/orclstu/sysaux01.dbf channel ORA_DISK_1: restoring datafile 00003 to /data/oracle/orclstu/undotbs01.dbf channel ORA_DISK_1: restoring datafile 00004 to /data/oracle/orclstu/users01.dbf channel ORA_DISK_1: restoring datafile 00005 to /data/oracle/orclstu/orclstuk01.dbf channel ORA_DISK_1: restoring datafile 00006 to /data/oracle/orclstu/plas01.dbf channel ORA_DISK_1: restoring datafile 00007 to /data/oracle/orclstu/plcrm01.dbf channel ORA_DISK_1: restoring datafile 00008 to /data/oracle/orclstu/pl01.dbf channel ORA_DISK_1: restoring datafile 00009 to /data/oracle/orclstu/help01.dbf channel ORA_DISK_1: reading from backup piece /oracle/backup/2016-03-17/full_POWERDES_20160317_14.bak channel ORA_DISK_1: piece handle=/oracle/backup/2016-03-17/full_POWERDES_20160317_14.bak tag=TAG20160317T202130 channel ORA_DISK_1: restored backup piece 1 channel ORA_DISK_1: restore complete, elapsed time: 00:14:25 Finished restore at 17-MAR-16 RMAN>
9，应用归档日志恢复数据文件
RMAN> recover database; Starting recover at 17-MAR-16 using channel ORA_DISK_1 starting media recovery channel ORA_DISK_1: starting archived log restore to default destination channel ORA_DISK_1: restoring archived log archived log thread=1 sequence=1428 channel ORA_DISK_1: reading from backup piece /oracle/backup/2016-03-17/arch_POWERDES_20160317_16.bak channel ORA_DISK_1: piece handle=/oracle/backup/2016-03-17/arch_POWERDES_20160317_16.bak tag=TAG20160317T202918 channel ORA_DISK_1: restored backup piece 1 channel ORA_DISK_1: restore complete, elapsed time: 00:00:03 archived log file name=/oracle/app/oracle/flash_recovery_area/POWERDES/archivelog/2016_03_17/o1_mf_1_1428_cgog3ons_.arc thread=1 sequence=1428 channel 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=906760822 unable to find archived log archived log thread=1 sequence=1429 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of recover command at 03/17/2016 22:00:29 RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 1429 and starting SCN of 31576222 RMAN>
须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-16 using channel ORA_DISK_1 starting media recovery media recovery complete, elapsed time: 00:00:00 Finished recover at 17-MAR-16 RMAN>
10，打开数据库
RMAN> alter database open resetlogs; database opened RMAN>
11，验证数据库
