微软云 azure 数据迁移之oracle11g dataguard

时间:2021-12-07 08:30:42

背景,将本地的oracle数据迁移到微软云azure云上面的oracle服务器。

1,复制本地的rman备份集到微软云azure的oracle服务器上

scp -r -P56922 2016-02-04 142.119.218.19:/oracle/

2,复制本地的控制文件到微软云azure上面的oracle服务器

查看备份文件:

rlwrap rman target /
list backup of spfile;
list backup of controlfile;

两者的最后一个文件都是一样的:

RMAN>  list backup of controlfile;                                                                                                                                                             

using target database control file instead of recovery catalog

复制备份的控制文件:

scp -r -P56922 /pddata2/oracle/backup/data/ctl_auto/c-3391761643-20160204-01 142.119.218.19:/oracle/

3,然后去微软云的oracle服务器上面进行恢复:

去参数文件查看微软云control的路径:

[oracle@pldb1 powerdes]$ more /oracle/initpowerdes.ora  |grep control_files
*.control_files='/home/oradata/powerdes/control01.ctl','/oracle/app/oracle/flash_recovery_area/powerdes/control02.ctl'
[oracle@pldb1 powerdes]$

看到有2个文件,所以rman需要恢复2个控制文件:

RMAN> restore controlfile to '/home/oradata/powerdes/control01.ctl' from '/oracle/c-3391761643-20160204-01';

Starting restore at 04-FEB-16
using channel ORA_DISK_1

channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:03
Finished restore at 04-FEB-16

RMAN>
RMAN> restore controlfile to '/oracle/app/oracle/flash_recovery_area/powerdes/control02.ctl' from '/oracle/c-3391761643-20160204-01';

Starting restore at 04-FEB-16
using channel ORA_DISK_1

channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:03
Finished restore at 04-FEB-16

RMAN>

4,将数据库状态改成mount:

RMAN> alter database mount;

database mounted
released channel: ORA_DISK_1

RMAN>

5,注册备份文件:

RMAN> catalog start with '/oracle/2016-02-04';

Starting implicit crosscheck backup at 04-FEB-16

channel ORA_DISK_1: SID=19 device type=DISK

6,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。

RMAN> restore database;

Starting restore at 04-FEB-16
using channel ORA_DISK_1

channel ORA_DISK_1: reading from backup piece /oracle/2016-02-04/full_POWERDES_20160204_5382.bak

这个过程时间有些漫长,没写入一个数据文件,后台alert日志都会记录的,如下所示:

[oracle@pldb1 powerdes]$ tail -f /oracle/app/oracle/diag/rdbms/powerdes/powerdes/trace/alert_powerdes.log

最后restore database结束:

RMAN>

看到RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 42422 and starting SCN of 11923509947,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
查看备份库的归档目录:

[oracle@localhost archivelog]$ find /oracle -name archivelog
/oracle/app/oracle/flash_recovery_area/archivelog
[oracle@localhost archivelog]$ cd /oracle/app/oracle/flash_recovery_area/archivelog

开始copy操作:

[oracle@localhost archivelog]$ scp -P56922 *.dbf 142.119.218.19:/oracle/app/oracle/flash_recovery_area/archivelog/

[oracle@localhost archivelog]$

然后在微软云azure的oracle库上,退出rman,重新登录rman执行recover database操作,如果不退出rman重新登录是识别不了新的copy过来的归档日志的:

RMAN> exit

发现还是在报错,42436这个归档日志没有,再去原来的备份库上看,42436是最新的归档日志,应该是刚刚生成的新的归档日志了:

然后copy这个归的归档日志到微软云azure的oracle库,然后退出rman后再进行recover恢复操作:

[oracle@localhost archivelog]$ scp -P56922 1_42436_821708334.dbf 142.119.218.19:/oracle/app/oracle/flash_recovery_area/POWERDES/archivelog/

RMAN>

why?会有42437的提示?我自己猜猜是:看到有新的提示了,42437归档日志没有了,这个时候,再去原来备份的库看到42437还没有正式生成,所以这里表明已经恢复到最新记录了,这里报是因为我是copy的归档日志,但是控制文件是以前的全备份的时候的,跟现在旧的备份库的有差异,所以会提示归档日志没有恢复到。这个时候就可以采用基于SCN的方式来recover database了:

采用scn的方式来recover database:

RMAN> recover database until scn 11924899775;

Starting recover at 04-FEB-16
using channel ORA_DISK_1

starting media recovery
media recovery complete, elapsed time: 00:00:00

然后再试试分开,先mount然后open:

查看后台alert日志信息:

看到是因为原来的本地环境是dg模式,而这里azure只有一个单机,所以将dg变成单机最大性能模式,然后再打开试试。

9,在本地测试连接下

然后在本地tnsnames.ora配置,58427端口是微软云azure上面映射的1521端口,通过58427可以访问到1521

AZURE.PD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 142.119.218.19)(PORT = 58427))
)
(CONNECT_DATA =
(SID = powerdes)
)
)

通过plsql连接微软云azure的oracle数据库,做个简单的测试,OK成功了。

SQL> create table z(id number);
Table created
SQL> insert into z values(1);
1 row inserted
SQL> commit;

SQL> select * from z;

10,PS:Oracle rman中recover和restore的区别:

restore just copy the physical file, recover will consistent the database.

restore 是还原,文件级的恢复。就是物理文件还原。
recover 是恢复,数据级的恢复。逻辑上恢复,比如应用归档日志、重做日志,全部同步,保持一致。

用我自己的土话讲就是,用restore先把备份文件拷贝到数据库目录下进行替换,再用recover经过一些处理,数据库就恢复正常了。

10.1、restore 命令:用于还原已经备份的数据文件。
(1)、restore database 还原所有的数据文件。
(2)、restore tablespace 还原特定表空间的数据文件。
(3)、restore datafile 还原特定的数据文件。
(4)、restore controlfile 还原控制文件。
(5)、restore archivelog 还原归档日志文件。

10.2、recover 命令:当数据库需要应用归档日志文件恢复数据文件时,使用recover命令。使用该命令数据库系统会自动应用归档的日志文件。
(1)、recover database 恢复所有的数据文件。
(2)、recover tablespace 恢复特定表空间的数据文件。
(3)、recover datafile 恢复特定的数据文件。
