【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。

一.2.4 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：
| 项目 | source db | target db |
| db 类型 | 单实例 | rac环境 |
| db version | 11.2.0.1 | 11.2.0.1 |
| ORACLE_SID | orastrac | orastrac1 和 orastrac2 |
| db_name | orastrac | orastrac |
| 主机IP地址： |
192.168.59.129 | 192.168.1.31 192.168.1.32 |
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 /

一.3.2.3 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直接传递到rac环境的第一个节点。
源库scp操作：
[oracle@orcltest ~]$ cd rman_back/
[oracle@orcltest rman_back]$ ll

*.audit_trail='db'
*.compatible='11.2.0.0.0'

*.remote_login_passwordfile='EXCLUSIVE'

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;

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

[oracle@node2 ~]$ srvctl add database -d orastrac -h
Adds a database configuration to the Oracle Clusterware.
Usage: srvctl add database -d <db_unique_name> -o <oracle_home> [-m <domain_name>] [-p <spfile>] [-r {PRIMARY | PHYSICAL_STANDBY | LOGICAL_STANDBY | SNAPSHOT_STANDBY}] [-s <start_options>] [-t <stop_options>] [-n <db_name>] [-y {AUTOMATIC | MANUAL}] [-g "<serverpool_list>"] [-x <node_name>] [-a "<diskgroup_list>"]
-d <db_unique_name> Unique name for the database
-o <oracle_home> ORACLE_HOME path
-x <node_name> Node name. -x option is specified for single-instance databases
-m <domain> Domain for database. Must be set if database has DB_DOMAIN set.
-p <spfile> Server parameter file path
-r <role> Role of the database (primary, physical_standby, logical_standby, snapshot_standby)
-s <start_options> Startup options for the database. Examples of startup options are open, mount, or nomount.
-t <stop_options> Stop options for the database. Examples of shutdown options are normal, transactional, immediate, or abort.
-n <db_name> Database name (DB_NAME), if different from the unique name given by the -d option
-y <dbpolicy> Management policy for the database (AUTOMATIC or MANUAL)
-g "<serverpool_list>" Comma separated list of database server pool names
-a "<diskgroup_list>" Comma separated list of disk groups
-h Print usage

上述 3 条命令分别配置了数据库和两个实例，此时 3 项服务刚刚配置完成，crs 中尚未同步其状态，因此需要执行一下 srvctl start database，然后再通过 crs_stat 即可查看正确的状态了。
OK，现在已经是集群的数据库了，整个恢复工作基本完成。剩下的比如修改监听、配置网络服务名，创建密钥文件等操作相信大家已经熟悉的不能再熟悉，这里不再演示相关操作了(注意密钥文件也是建议创建到共享存储端，否则的话就得在各个节点分别创建一份)。
一.3.4 实验总结
单实例的数据库备份集恢复到rac环境下其实很简单，和一般的恢复步骤都一样的，不过在恢复spfile、control file及datafile的时候需要放在共享存储里边，另外恢复完成后需要修改一些集群相关的参数才可以转换为集群数据库。
一.4 总结
到此所有的处理算是基本完毕，过程很简单，但是不同的场景处理方式有很多种，我们应该学会灵活变通。
