一.2.4  本文简介

 

  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。

 

 

另外注意，BLOG中代码部分需要特别关注的地方我都用黄色背景和红色字体来表示，比如下边的例子中，thread 1的最大归档日志号为33，thread 2的最大归档日志号为43是需要特别关注的地方。

一.3  实验部分

 

一.3.1  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。

 

一.3.2  源rac库执行

rac库需要执行备份并传递到目标库。

 

一.3.2.1  查看rac环境及创建测试表

我后续将在192.168.1.32即rac的第二个节点上执行操作，db_name为jmrac，数据库为归档模式，创建测试表lhr.rac_to_single_test，数据量为72510 行，其中有个crsstat命令，可以参考：【RAC】如何让Oracle RAC crs_stat 命令显示完整  http://blog.itpub.net/26736162/viewspace-1610957/

一.3.2.3  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/rman_back/full_%n_%T_%t_%s_%p.bak‘;

sql ‘alter system archive log current‘;

backup archivelog all format ‘/home/oracle/rman_back/arch_%d_%T_%s_%p.bak‘ delete input;

backup current controlfile format ‘/home/oracle/rman_back/ctl_%d_%T_%s_%p.bak‘;

release channel c1;

release channel c2;

}

 

 

执行过程如下：

[oracle@node2 ~]$ rman target /

一.3.2.4  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：

[oracle@orcltest ~]$ ifconfig

至此，源库rac上需要操作的内容已完成。

 

 

一.3.3  target库上执行

一.3.3.1  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：

最终修改完之后，这里的初始化参数如下，比如原来的文件精简不少：

[oracle@orcltest rman_back]$ more initjmrac.ora

[oracle@orcltest onlinelog]$ mkdir -p /u01/app/oracle/admin/jmrac/adump

[oracle@orcltest onlinelog]$ mkdir -p /u01/app/oracle/oradata/jmrac/

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：

SQL> select ‘set newname for datafile ‘ || a.FILE# || ‘ to "‘ || a.NAME || ‘";‘

  2    from v$datafile a

  3  union all

  4  select ‘set newname for tempfile ‘ || a.FILE# || ‘ to "‘ || a.NAME || ‘";‘

  5    from v$tempfile a

  6  union all

  7  SELECT ‘SQL "ALTER DATABASE RENAME FILE ‘‘‘‘‘ || a.MEMBER || ‘‘‘‘‘  to  ‘‘‘‘‘ ||

  8         a.MEMBER || ‘‘‘‘‘ ";‘

  9    FROM v$logfile a;

二、 recover数据库

由前边的备份集中可以看出，备份集中的thread 1的最大日志号为33，thread 2的最大日志号为43，所以不完全恢复如下：

 

RMAN> RUN

2> {

3> set until sequence 33 thread 1;

set until sequence 43 thread 2;

recover database;

}

4> 5> 6>

可以看到数据已经恢复。

一.3.3.5  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：

一、 清除未使用的redo

 

 

SQL> col instance format a8

SQL> select thread#,instance,status,enabled from v$thread;

 

   THREAD# INSTANCE STATUS ENABLED

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

         1 jmrac    OPEN   PUBLIC

         2 jmrac2   CLOSED PUBLIC

 

SQL> select group#,thread#,archived,status from v$log;

 

    GROUP#    THREAD# ARC STATUS

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

         1          1 NO  CURRENT

         2          1 YES UNUSED

         3          2 YES ACTIVE

         4          2 YES UNUSED

 

SQL> alter database disable thread 2 ;

 

Database altered.

 

SQL> alter database drop logfile group 3 ;

 

Database altered.

 

 

SQL> alter database drop logfile group 4 ;

 

Database altered.

 

SQL>

 

SQL>  select thread#,instance,status,enabled from v$thread;

 

   THREAD# INSTANCE STATUS ENABLED

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

         1 jmrac    OPEN   PUBLIC

 

SQL>

SQL> select group#,thread#,archived,status from v$log;

 

    GROUP#    THREAD# ARC STATUS

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

         1          1 NO  CURRENT

         2          1 YES UNUSED

 

SQL>

 

 

生产环境可以再增加一些日志组。

 

 

 

二、 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.

 

SQL>

 

 

 

 

一.3.4  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。

 

一.4  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。
