前言部分

导读

各位技术爱好者,看完本文后,你可以掌握如下的技能,也可以学到一些其它你所不知道的知识,~O(∩_∩)O~:

① rac数据库的备份集是如何恢复到单实例的数据库

② ASM文件系统到OS文件系统的转换

③ 一般的备份恢复过程

实验环境介绍

源库:11.2.0.1 rac库 2个节点

目标库:11.2.0.1 RHEL6.5

本文也可以理解成rac环境下的如何数据库迁移到单实例的数据库环境下,默认目标库已经安装好了同源库一样的数据库版本。

实验部分

实验目标

将11.2.0.1下的rac库备份并恢复到11.2.0.1下的单实例环境下。

源rac库执行

rac库需要执行备份并传递到目标库。

执行备份操作

备份脚本如下:

run

{

allocate channel c1 type disk;

allocate channel c2 type disk;

backup database format '/home/oracle/rmanback/full%n%T%t%s%p.bak';

sql 'alter system archive log current';

backup archivelog all format '/home/oracle/rmanback/arch%d%T%s_%p.bak' delete input;

backup current controlfile format '/home/oracle/rmanback/ctl%d%T%s_%p.bak';

release channel c1;

release channel c2;

}

执行过程如下:

[oracle@node2 ~]$ rman target /

[oracle@node2 rman_back]$

将备份传递到target库

这个方法就多了,可以采用ftp上传下载,也可以采用NFS网络文件系统,或者scp命令都可以,这里我们采用scp直接传递。

源库:

[oracle@node2 rman_back]$ scp -r /home/oracle/rman_back oracle@192.168.59.129:/home/oracle

ssh: connect to host 192.168.59.129 port 22: Network is unreachable

lost connection

由于source db的IP为192.168.1.32,而目标库的IP为192.168.59.129,不在同一个网段,所以我对目标库再添加一块网卡,所以目标库的IP配置如下:

目标库再添加一块网卡后:

至此,源库rac上需要操作的内容已完成。

target库上执行

修改pfile文件生成spfile文件、生成pfile中的文件路径

主要有两方面的修改:

  • 修改含文件路径的参数,达到符合当前服务器环境的实际情况,如audit_file_dest,control_files,db_recovery_file_dest
  • 修改多实例相关的参数,如 cluster_database,带有实例名的前缀

源pfile文件内容:

这里需要注意的是,数据文件的转换,由于原rac库是asm存储的,所以到新环境需要采用set newname来转换一下,相关的可以参考哥的blog:【oracle官网】 Restoring a Database on a New Host http://blog.itpub.net/26736162/viewspace-1548104/,这里就直接操作了。

先得到转换的脚本:

后续收尾操作

做到这步,都还没有完啊,只是说目的基本达成,最后还需要收尾的工作。清除未使用线程的 redo 日志组,操作如下:

清除未使用的redo

生产环境可以再增加一些日志组。

清除多余的 undo 文件

我们知道rac中每个节点使用的都是自己的undo,所以有2个undo文件,这里可以清除,也可以不用清除,因为有的时候undo坏了可以很迅速的切换到另外的undo空间,清理过程如下:

SQL> select name from v$tablespace where name like 'UNDO%';

NAME

------------------------------

UNDOTBS1

UNDOTBS2

SQL> show parameter undo_tablespace;

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

undo_tablespace string UNDOTBS1

SQL> drop tablespace undotbs2 including contents and datafiles;

Tablespace dropped.

实验总结

rac数据库迁移到单实例环境下的步骤和单实例的数据库迁移到单实例环境基本是一样的,只是在最后还原的时候需要设置2个thread即可。

总结

至此,rac数据库迁移到单实例环境下的操作步骤基本完毕,至于配置监听和tns等工作都是基本的,大家自己完成即可,这里就不再演示了,另外实验中需要关注的几个地方,我都特别做了说明。

How To Restore RMAN Disk backups of RAC Database to Single Instance On Another Node (文档 ID 415579.1)

APPLIES TO:

Oracle Database - Enterprise Edition - Version 9.2.0.1 and later
Information in this document applies to any platform.
Checked for relevance on 15-Apr-2014

GOAL

- You have a RAC database backed up by RMAN to disk location
- You need to restore this backup as Single Instance on another node

SOLUTION

\1) Take appropriate RMAN backup of the production RAC database. Note that you should turn on the CONTROLFILE AUTOBACKUP configuration so that we have the controlfile backed up after the database backup. When we restore the controlfile on new host from this autobackup piece, it will have the information of the latest backup.

RMAN> run{
2> allocate channel c1 type disk format '/oracle/10g/backup/%U';
3> backup database;
4> backup archivelog all;
5> }

released channel: c1

\2) Create a PFILE for the single instance database using the production RAC parameter file
a) don't forget to modify the following parameters depending on the directory structure of the new host: audit_file_dest, background_dump_dest, control_files, core_dump_dest, log_archive_dest_1, user_dump_dest etc
b) remove RAC specific parameters such as cluster_database_instances, cluster_database etc
c) for the parameter undo_tablespace, mention any one undo tablespace name

Known issue which may require an additional parameter to be set :
Note 334899.1 RMAN Duplicate from RAC backup fails ORA-38856

\3) Move the backup pieces and the modified INIT.ORA file to the new host. Starting from 10g it is NO longer compulsory to copy the RMAN backup pieces to exactly the same location on the new host as the production location.

\4) Use the pfile created above to STARTUP NOMOUNT the database on the new host

\5) Now invoke RMAN and restore the controlfile specifying the location where the controlfile autobackup piece is restored on this new server. You can mount the database once the controlfile is restored successfully.

connected to target database: racdb (not mounted)
using target database control file instead of recovery catalog

RMAN> restore controlfile from '/u01/oracle/oradata/ractest/c-610677177-20070212-00';

Starting restore at 16-FEB-07
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=156 devtype=DISK

channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:02
output filename=/u01/oracle/oradata/ractest/control01.ctl
Finished restore at 16-FEB-07

RMAN> alter database mount;

database mounted
released channel: ORA_DISK_1

\6) You can skip this step if you have restored the RMAN backup pieces to exactly the same location they were backed up on production. If this is not the case then you need to catalog the RMAN backup pieces to make RMAN aware of thier new location on the new host. Note that CATALOG BACKUPPIECE command is available only starting from 10g.

RMAN> catalog backuppiece '/u01/oracle/oradata/ractest/09i9sruq_1_1';

cataloged backuppiece
backup piece handle=/u01/oracle/oradata/ractest/09i9sruq_1_1 recid=10 stamp=614661579

RMAN> catalog backuppiece '/u01/oracle/oradata/ractest/0ai9ss14_1_1';

cataloged backuppiece
backup piece handle=/u01/oracle/oradata/ractest/0ai9ss14_1_1 recid=11 stamp=614661599

\7) Now we'll determine the point upto which media recovery should run on the restored database.

RMAN> list backup of archivelog all;

List of Archived Logs in backup set 9
Thrd Seq Low SCN Low Time Next SCN Next Time


1 56 214541 01-FEB-07 226238 01-FEB-07
1 57 226238 01-FEB-07 226240 01-FEB-07
1 58 226240 01-FEB-07 233107 12-FEB-07
2 1 186185 28-JAN-07 225714 01-FEB-07
2 2 225714 01-FEB-07 226037 01-FEB-07
2 3 226037 01-FEB-07 233110 12-FEB-07

Check the last archive sequence for all redo threads and select the archive sequence having LEAST "Next SCN" among them. In our case sequence 58 of thread 1 has Next SCN of 233107 while sequence 3 of thread 2 has Next SCN of 233110. Since squence 58 of thread 1 has least Next SCN we will recover upto this point. (If you are keen to have recovery run until some specific time you can always give SET UNTIL TIME)

\8) Having determined the point upto which media recovery should run, start the restore/recovery using:
Please note in below example we choose Until sequence as 59(one more then the value selected in step 7 that is sequence 58) because When we specify a sequence number, it is considered as an UPPER limit , RMAN selects only
those files which are needed for the recovery and uses 59 as an upper log sequence number while recovering database and would recovery upt log sequence number upto 58 .

RMAN> run {
2> set until sequence 59 thread 1;
3> set newname for datafile 1 to '/u01/oracle/oradata/ractest/data/system01.dbf';
4> set newname for datafile 2 to '/u01/oracle/oradata/ractest/data/undotbs01.dbf';
5> set newname for datafile 3 to '/u01/oracle/oradata/ractest/data/sysaux01.dbf';
6> set newname for datafile 4 to '/u01/oracle/oradata/ractest/data/users01.dbf';
7> set newname for datafile 5 to '/u01/oracle/oradata/ractest/data/undotbs02.dbf';
8> restore database;
9> switch datafile all;
10> recover database;
11> }

In case you want to have the datafiles on a ASM diskgroup (+DATA for eg) for the clone/destination database, you may use SET NEWNAME as below:

set newname for datafile 1 to '+DATA';
set newname for datafile 2 to '+DATA';
....

Known issue in Oracle10g:
Note 1146703.1 Rman Restore From RAC ASM To Single Instance Non ASM Fails With ORA-00600 [kgeade_is_0]

CAUTION !!!!:

If Online Redolog's (ORL's) are Oracle Managed Files (OM), and the Clone is being done on any of Source RAC Node (where ORLs are accessible from), renaming ORL will try to remove Source ORL files!

Please review: http://docs.oracle.com/cd/E11882_01/server.112/e25494/omf.htm#ADMIN11517

The following statements are used to rename files:

ALTER DATABASE RENAME FILE

ALTER TABLESPACE ... RENAME DATAFILE

These statements do not actually rename the files on the operating system, but rather, the names in the control file are changed. If the old file is an Oracle managed file and it exists, then it is deleted. You must specify each filename using the conventions for filenames on your operating system when you issue this statement."

Instead of renaming, we can recreate the controlfile with desired name for ORLs:

SQL> alter database backup controlfile to trace as '/tmp/control.sql' resetlogs ;

Edit /tmp/control.sql and modify desired ORL names.

Since we determined previously that media recovery should run until sequence 58 hence we use SET UNTIL SEQUENCE 59 (+1) above. You also need to use SET NEWNAME clause to restore datafiles to a location on the new host which is different from the production path. Finally, SWITCH DATAFILE ALL clause updates these new datafile locations in the controlfile.

\9) Once RMAN restore/recovery finishes, you will want to rename the online redolog files before opening the database in case the production path of redo log files is not available on the new host. After renaming the redolog files, the database can be opened with RESETLOGS

SQL> select member from v$logfile;

MEMBER
--------------------------------------------------------------------------------
/ocfs2/oradata/racdb/redo01.log
/ocfs2/oradata/racdb/redo02.log
/ocfs2/oradata/racdb/redo03.log
/ocfs2/oradata/racdb/redo04.log
/ocfs2/oradata/racdb/redo05.log
/ocfs2/oradata/racdb/redo06.log

6 rows selected.

SQL> alter database rename file '/ocfs2/oradata/racdb/redo01.log' to '/u01/oracle/oradata/ractest/log/redo01.log';

Database altered.

SQL> alter database rename file '/ocfs2/oradata/racdb/redo02.log' to '/u01/oracle/oradata/ractest/log/redo02.log';

Database altered.

SQL> alter database rename file '/ocfs2/oradata/racdb/redo03.log' to '/u01/oracle/oradata/ractest/log/redo03.log';

Database altered.

SQL> alter database rename file '/ocfs2/oradata/racdb/redo04.log' to '/u01/oracle/oradata/ractest/log/redo04.log';

Database altered.

SQL> alter database rename file '/ocfs2/oradata/racdb/redo05.log' to '/u01/oracle/oradata/ractest/log/redo05.log';

Database altered.

SQL> alter database rename file '/ocfs2/oradata/racdb/redo06.log' to '/u01/oracle/oradata/ractest/log/redo06.log';

Database altered.

SQL> alter database open resetlogs;

Database altered.

In case you want to create the online redo logs on a ASM diskgroup (+DATA for eg) for the clone/destination database, you may use below commands:

alter database rename file '/ocfs2/oradata/racdb/redo01.log' to '+DATA';
alter database rename file '/ocfs2/oradata/racdb/redo02.log' to '+DATA';
...

\10) Once the database is opened successfully, you may remove the redolog groups for redo threads of other instances

SQL> select THREAD#, STATUS, ENABLED
2 from v$thread;

THREAD# STATUS ENABLED


SQL> select group# from v$log where THREAD#=2;

GROUP#
----------
4
5
6

SQL> alter database disable thread 2;

Database altered.

SQL> alter database drop logfile group 4;
alter database drop logfile group 4
*
ERROR at line 1:
ORA-00350: log 4 of instance racdb2 (thread 2) needs to be archived
ORA-00312: online log 4 thread 2: '/u01/oracle/oradata/ractest/log/redo04.log'

SQL> alter database clear unarchived logfile group 4;

Database altered.

SQL> alter database drop logfile group 4;

Database altered.

SQL> alter database drop logfile group 5;

Database altered.

SQL> alter database drop logfile group 6;

Database altered.

SQL> select THREAD#, STATUS, ENABLED from v$thread;

THREAD# STATUS ENABLED


\11) Now you can remove the undo tablespaces of other instances and create a new temporary tablespace to complete the activity.

SQL> sho parameter undo;

NAME TYPE VALUE


undo_management string AUTO
undo_retention integer 900
undo_tablespace string UNDOTBS1
SQL>
SQL>
SQL> select tablespace_name from dba_tablespaces where contents='UNDO';

TABLESPACE_NAME
------------------------------
UNDOTBS1
UNDOTBS2

SQL> drop tablespace UNDOTBS2 including contents and datafiles;

Tablespace dropped.

SQL> select name from v$tempfile;

NAME
--------------------------------------------------------------------------------
/ocfs2/oradata/racdb/temp01.dbf

SQL> select tablespace_name from dba_tablespaces where contents='TEMPORARY';

TABLESPACE_NAME
------------------------------
TEMP

SQL> create temporary tablespace TEMP1
2 tempfile '/u01/oracle/oradata/ractest/data/temp01.dbf'
3 size 50M;

Tablespace created.

SQL> alter database default temporary tablespace TEMP1;

Database altered.

SQL> drop tablespace TEMP including contents and datafiles;

Tablespace dropped.
