【RAC】将单实例备份集恢复为rac数据库

一.1  BLOG文档结构图

一.2  前言部分

一.2.1  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 单实例环境的备份集如何恢复到rac环境(重点)

② rman恢复数据库的一般步骤

③ rac环境的简单操作

注意：本篇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。

一.2.2  实验环境介绍

源库：11.2.0.1   RHEL6.5 单实例

目标库：11.2.0.1  RHEL6.5  rac环境

一.2.3  相关参考文章链接

rac安装系列：

一.2.4  本文简介

本文基于如何将单实例的数据库备份恢复到rac环境下，至于rac环境的备份集如何恢复到单实例及rac环境的备份集恢复到rac环境的实验请参考相关文章链接部分。

实验的一些数据库环境参考如下表格：

先描述下大致步骤：

? 源端创建备份集；

? 目标端安装数据库软件和集群件，并配置好共享存储（安装rac的时候一般已经配置好了）；

? 复制源端备份集到目标端；

? 目录端任意节点执行正常恢复，恢复时注意要将 spfile,controlfile,datafile,redofile 等路径改到共享存储上，恢复完后这会儿仍然是个单实例数据库；

? 修改初始化参数、增加 UNDO 表空间、增加 REDOLOG 线程组，重建密钥文件，目标端任意节点执行；

? 目标端各个节点配置监听及网络服务名；

? 将新建的数据库配置到 crs，目标端任意节点执行即可。

一.3  实验部分

一.3.1  实验目标

将单实例的备份集成功的恢复到rac环境下，并添加数据库到crs环境。

一.3.2  源库操作

source库上需要做的操作主要是备份和创建测试用户。

一.3.2.1  静默创建一个单实例的测试库

首先修改归档模式，这样创建的数据库默认为归档模式，然后我们在源库上静默创建一个单实例的库，sid为orastrac，为oracle single instance to rac，关于静默安装数据库参考：

一.3.2.2  source库执行备份操作

备份脚本如下，注意控制文件需要最后备份：

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@orcltest ~]$ rman target /

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直接传递到rac环境的第一个节点。

修改与路径相关的参数，修改后如下：

*.open_cursors=300

*.processes=150

*.remote_login_passwordfile=‘EXCLUSIVE‘

*.undo_tablespace=‘UNDOTBS1‘

插曲：注意，这里如果想让控制文件的格式为ASM格式，可以这样设置控制文件的路径：

pfile文件中的control_files这样写： *.control_files=‘+DATA‘,‘+ARCH‘，然后还原的时候就可以直接还原为asm格式的文件了，我这里由于是后边补上的，所以就不采用如下的形式了，如下：

RMAN> restore controlfile   from ‘/home/oracle/rman_back/ctl_ORASTRAC_20150601_7_1.bak‘;

创建os文件路径，注意在节点一和节点二都执行：

[oracle@node1 ~]$ mkdir -p /u01/app/oracle/admin/orastrac/adump

[oracle@node1 ~]$

注意哟，创建的 spfile 可是要放到共享存储上去的：

此时的数据库还是单实例的，需要启用集群特性来转换为rac数据库。

一.3.3.6  启用集群特性用于转换为RAC环境的数据库

需要修改如下几类参数：

一、 指定实例参数

[oracle@node1 dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Mon Jun 1 16:12:03 2015

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production

With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,

Data Mining and Real Application Testing options

SQL> col parameter format a50

SQL> set line 9999

SQL>  select * from v$option where parameter = ‘Real Application Clusters‘;

PARAMETER                                          VALUE

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

Real Application Clusters                          TRUE

SQL> show parameter cluster

NAME                                 TYPE        VALUE

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

cluster_database                     boolean     FALSE

cluster_database_instances           integer     1

cluster_interconnects                string

SQL>

由上述返回结果可知，RAC 特性是支持的，不过尚未启用集群数据库，因此接下来首先要改的，就是 enable CLUSTER DATABASE，操作如下：

SQL> show parameter spfile

NAME                                 TYPE        VALUE

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

spfile                               string      +DATA/orastrac/parameterfile/s

                                                 pfile.335.881250575

SQL>  alter system set cluster_database=true scope=spfile;

System altered.

SQL>

SQL> alter system set cluster_database_instances=2 scope=spfile;

System altered.

SQL>  alter system set instance_number=1 scope=spfile sid=‘orastrac1‘;

System altered.

SQL>  alter system set instance_number=2 scope=spfile sid=‘orastrac2‘;

System altered.

SQL> alter system set thread=1 scope=spfile sid=‘orastrac1‘;

System altered.

SQL> alter system set thread=2 scope=spfile sid=‘orastrac2‘;

System altered.

SQL>

二、 增加undo

新建一组 UNDO 表空间和线程 2 使用的两组 REDO 文件：

SQL> select * from v$tablespace;

       TS# NAME                           INC BIG FLA ENC

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

         0 SYSTEM                         YES NO  YES

         1 SYSAUX                         YES NO  YES

         2 UNDOTBS1                       YES NO  YES

         4 USERS                          YES NO  YES

         3 TEMP                           NO  NO  YES

         6 EXAMPLE                        YES NO  YES

6 rows selected.

SQL>  create undo tablespace undotbs2 datafile ‘+DATA‘ SIZE 50m;

Tablespace created.

SQL> alter system set undo_tablespace=‘undotbs1‘ scope=spfile sid=‘orastrac1‘;

System altered.

SQL> alter system set undo_tablespace=‘undotbs2‘ scope=spfile sid=‘orastrac2‘;

System altered.

三、 增加redo

SQL> select * from v$log;

    GROUP#    THREAD#  SEQUENCE#      BYTES  BLOCKSIZE    MEMBERS ARC STATUS           FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# NEXT_TIME

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

SQL>  alter database add logfile thread 2 group 4 ‘+arch‘ size 50M;

Database altered.

SQL> alter database add logfile thread 2 group 5 ‘+arch‘ size 50M;

Database altered.

SQL> alter database add logfile thread 2 group 6 ‘+arch‘ size 50M;

一.3.3.7  重启数据库

重启数据库，在每个节点上修改pfile文件：

一、 节点一
