一、准备环境
1、单实例配置
数据库版本：Oracle 11.2.0.4
操作系统：CentOS 6.5

2、RAC配置（数据库实例未装载）
服务器主机名 rac1 rac2
公共IP地址(eth0) 192.168.91.140 192.168.91.142
虚拟IP地址(eth0) 192.168.91.152 192.168.91.153
私有IP地址(eth1) 192.168.1.130 192.168.1.131
名称 说明
SCAN IP 192.168.91.154
集群实例名称 orcl
操作系统 CentOS 6.5
ORACLE 11.2.0.4
存储 ASM

二、源数据库备份和参数文件复制到目标端
1、对源端数据库做全备
[oracle@orcl ~]$ mkdir -p /u01/app/oracle/backup/
[oracle@orcl archivelog]$ rman target /
Recovery Manager: Release 11.2.0.4.0 - Production on Fri Apr 21 13:09:57 2017

2、创建参数文件pfile
[oracle@orcl ~]$ sqlplus / as sysdba

3、把备份集传到目标数据库rac1上
[oracle@orcl~]$ scp -r /u01/app/oracle/backup/* oracle@192.168.91.140:/u01/app/oracle/backup/
目标端rac1上确认
[oracle@rac1 ~]$ ll /u01/app/oracle/backup
total 2386364

三、目标端数据恢复
1、配置oracle用户的环境变量（所有的节点执行,SID稍有差异）
[oracle@rac1 ~]$ vi ~/.bash_profile
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export ORACLE_SID=orcl1
export PATH=/usr/sbin:$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
umask 022
[oracle@rac1 ~]$ source ~/.bash_profile

2、在共享磁盘上创建必要的目录
2.1 查看磁盘挂载情况
[root@rac1 ~]# su - grid
[grid@rac1 ~]$ sqlplus / as sysasm
SQL*Plus: Release 11.2.0.4.0 Production on Thu Apr 13 16:32:13 2017

Connected to:

SQL> col name for a10

2.2 共享磁盘上创建必要的目录
[grid@rac1 ~]$ asmcmd
ASMCMD> ls

ASMCMD> cd data
ASMCMD> mkdir ORCL
ASMCMD> cd orcl
ASMCMD> mkdir CONTROLFILE
ASMCMD> mkdir PARAMETERFILE

ASMCMD> mkdir ONLINELOG

3、在rac1本地磁盘上创建必要的目录（保险起见所有节点执行）
[oracle@rac1 ~]$ mkdir -p /u01/app/oracle/admin/orcl/adump
[oracle@rac1 ~]$ mkdir -p /u01/app/oracle/archivelog
[oracle@rac1 ~]$ mkdir -p /u01/app/oracle/oradata/orcl
[oracle@rac1 ~]$ mkdir -p /u01/app/oracle/backup

4、在rac1上编辑pfile文件（根据实际情况调整内存大小）
[oracle@rac1 backup]$ vi /tmp/pfile.ora

*.audit_file_dest=\'/u01/app/oracle/admin/orcl/adump\'
*.audit_trail=\'db\'
*.compatible=\'11.2.0.4.0\'
*.control_files=\'+DATA/orcl/controlfile/current.289.939812385\',\'+FRA/orcl/controlfile/current.286.939812387\'
*.db_block_size=8192
*.db_create_file_dest=\'+DATA\'
*.db_domain=\'\'
*.db_name=\'orcl\'
*.db_recovery_file_dest=\'+FRA\'
*.db_recovery_file_dest_size=4421074432
*.diagnostic_dest=\'/u01/app/oracle\'
*.disk_asynch_io=TRUE
*.filesystemio_options=\'SETALL\'
*.dispatchers=\'(PROTOCOL=TCP) (SERVICE=orclXDB)\'
*.enable_goldengate_replication=TRUE
*.log_archive_dest_1=\'LOCATION=+data/orcl/archivelog\'
*.log_archive_format=\'arch_%t_%s_%r.arc\'
*.open_cursors=300
*.pga_aggregate_target=302478720
*.processes=150
*.remote_login_passwordfile=\'EXCLUSIVE\'
*.cluster_database=false
*.sga_target=917436160
*.undo_management=\'AUTO\'
orcl1.instance_name=\'orcl1\'
orcl2.instance_name=\'orcl2\'
orcl1.instance_number=1
orcl2.instance_number=2
orcl1.thread=1
orcl2.thread=2
orcl1.undo_tablespace=\'UNDOTBS1\'
orcl2.undo_tablespace=\'UNDOTBS2\'
注：等数据库恢复完毕后，再cluster_database设置为true。还有如果用rman duplicate必须设置如下两个参数：
*.db_file_name_convert=\'/u01/app/oracle/oradata/orcl\',\'+DATA/orcl/datafile\'
*.log_file_name_convert=\'/u01/app/oracle/oradata/orcl\',\'+DATA/orcl/onlinelog\',\'/u01/app/oracle/oradata/orcl\',\'+FRA/orcl/onlinelog\'

5、恢复数据库(一)
5.1 用pfile文件创建spfile
[oracle@rac1 ~]$ su - oracle
[oracle@rac1 ~]$ sqlplus / as sysdba

5.2 将所有的节点上pfile文件，指向共享文件上的spfile文件
rac1节点:
[oracle@rac1 ~]$ echo "SPFILE=\'+DATA/orcl/spfileorcl.ora\' " > /u01/app/oracle/product/11.2.0/dbhome_1/dbs/initorcl1.ora
rac2节点:

5.3 创建口令文件
rac1节点:

[oracle@rac1 ~]$ ll /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapworcl1

四、配置数据库参数
1、查看数据情况
修改参数：
SQL> col value for a10
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> show parameter thread
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
parallel_threads_per_cpu integer 2
thread integer 1
SQL> show parameter instance_number
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
instance_number integer 1
SQL> alter system set cluster_database=true scope=spfile sid=\'*\';
System altered.
SQL> alter system set cluster_database_instances=2 scope=spfile sid=\'*\';
System altered.
SQL> alter system set instance_number=1 scope=spfile sid=\'orcl1\';
System altered.
SQL> alter system set instance_number=2 scope=spfile sid=\'orcl2\';
System altered.
SQL> alter system set thread=1 scope=spfile sid=\'orcl1\';
System altered.
SQL> alter system set thread=2 scope=spfile sid=\'orcl2\';
System altered.
SQL> show parameter undo_tablespace
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
undo_tablespace string UNDOTBS1
SQL> create undo tablespace UNDOTBS2 datafile \'+DATA/orcl/datafile/undotbs02.dbf\' size 100M;
Tablespace created.
SQL> alter system set undo_tablespace=\'UNDOTBS2\' scope=spfile sid=\'orcl2\';
System altered.
SQL> alter database add logfile thread 2 group 4 (\'+DATA\',\'+FRA\') size 50M;
Database altered.
SQL> alter database add logfile thread 2 group 5 (\'+DATA\',\'+FRA\') size 50M;
Database altered.
SQL> alter database add logfile thread 2 group 6 (\'+DATA\',\'+FRA\') size 50M;
Database altered.
注：根据实际情况分配日志文件大小，可以增加日志组文件
alter database add logfile member \'+FRA\' to group 4;
SQL> alter database enable thread 2;
Database altered
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

[oracle@rac1 ~]$ srvctl add database -d orcl -o $ORACLE_HOME -p +DATA/orcl/spfileorcl.ora
[oracle@rac1 ~]$ srvctl add instance -d orcl -i orcl1 -n rac1
[oracle@rac1 ~]$ srvctl add instance -d orcl -i orcl2 -n rac2

3、启动rac1和rac2实例
[oracle@rac1 ~]$ srvctl start database -d orcl -o open

4、 确认实例情况
[oracle@rac1 ~]$ sqlplus / as sysdba

6、重建 temp表空间
6.1 手工重建temp表空间
因为在 recover 的时候不会对temp 表空间进行recover。所以recover 后，我们要手工重建temp表空间。

[grid@rac1 ~]$ asmcmd lsof |grep temp
orcl orcl1 +data/orcl/tempfile/temp.266.941900557
[oracle@rac1 ~]$ sqlplus / as sysdba
SQL> alter tablespace temp add tempfile \'+DATA\' size 100M;
Tablespace altered.
SQL> select name from v$tempfile;
NAME
--------------------------------------------------------------------------------
+DATA/orcl/tempfile/temp.266.941900557
+DATA/orcl/tempfile/temp.267.941901771

SQL> alter database tempfile \'+DATA/orcl/tempfile/temp.266.941900557\' offline ;
Database altered.
SQL> alter database tempfile \'+DATA/orcl/tempfile/temp.266.941900557\' drop including datafiles;
alter database tempfile \'+DATA/orcl/tempfile/temp.266.941900557\' drop including datafiles
*
ERROR at line 1:
ORA-25152: TEMPFILE cannot be dropped at this time
6.2 重启数据库再删除原temp表空间
[oracle@rac1 oracle]$ srvctl stop database -d orcl -o immediate
[oracle@rac1 oracle]$ srvctl start database -d orcl -o open
[oracle@rac1 oracle]$ sqlplus / as sysdba

7.1 配置tnsnames.ora (所有节点执行)
[oracle@rac1 ~]$ su - oracle
[oracle@rac1 ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/network/admin
[oracle@rac1 admin]$ vi tnsnames.ora
ORCL =

(SERVICE_NAME = orcl)
)
)

7.2 启动监听
[oracle@rac1 admin]$ srvctl stop listener
[oracle@rac1 admin]$ srvctl start listener
[oracle@rac1 admin]$ srvctl status listener
Listener LISTENER is enabled
Listener LISTENER is running on node(s): rac2,rac1

7.3 用PC机测试
编辑tnsname： G:\\app\\oracle\\product\\11.2.0\\client_1\\network\\admin\\tnsnames.ora
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.91.152)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.91.153)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

运行 cmd ：
