2、建立引數檔案pfile
[oracle@wxqyh ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.4.0 Production on Fri Apr 21 13:12:16 2017
Copyright (c) 1982, 2013, Oracle. All rights reserved.

3、把備份集傳到目標資料庫rac1上
[oracle@wxqyh ~]$ scp -r /u01/app/oracle/backup/* oracle@192.168.91.140:/u01/app/oracle/backup/
目標端rac1上確認
[oracle@rac1 ~]$ ll /u01/app/oracle/backup
total 2386364

三、目標端資料恢復
1、配置oracle使用者的環境變數（所有的節點執行,SID稍有差異）
[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=wxqyh1
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、在共享磁碟上建立必要的目錄
2.1 檢視磁碟掛載情況
[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
Copyright (c) 1982, 2013, Oracle. All rights reserved.

------------ ---------- ---------- ------------------ ---------- ----------
1 DATA MOUNTED EXTERN 9992 9896
2 FRA MOUNTED EXTERN 4996 4902
3 OCRVOTE MOUNTED NORMAL 2997 2071
[grid@rac1 ~]$ asmcmd
ASMCMD> ls

ASMCMD> cd data
ASMCMD> mkdir WXQYH
ASMCMD> cd wxqyh
ASMCMD> mkdir CONTROLFILE
ASMCMD> mkdir PARAMETERFILE
ASMCMD> mkdir DATAFILE
ASMCMD> mkdir TEMPFILE
ASMCMD> mkdir ONLINELOG
ASMCMD> mkdir archivelog
ASMCMD> cd ../../fra
ASMCMD> mkdir WXQYH
ASMCMD> cd wxqyh
ASMCMD> mkdir ONLINELOG
ASMCMD> mkdir CONTROLFILE
3、在rac1本地磁碟上建立必要的目錄（保險起勁所有節點執行）
[oracle@rac1 ~]$ mkdir -p /u01/app/oracle/admin/wxqyh/adump
[oracle@rac1 ~]$ mkdir -p /u01/app/oracle/archivelog
[oracle@rac1 ~]$ mkdir -p /u01/app/oracle/oradata/wxqyh
[oracle@rac1 ~]$ mkdir -p /u01/app/oracle/backup
4、在rac1上編輯pfile檔案（根據實際情況調整記憶體大小）
[oracle@rac1 backup]$ vi /tmp/pfile.ora
*.audit_file_dest='/u01/app/oracle/admin/wxqyh/adump'
*.audit_trail='db'
*.compatible='11.2.0.4.0'
*.control_files='+DATA/wxqyh/controlfile/current.289.939812385','+FRA/wxqyh/controlfile/current.286.939812387'
*.db_block_size=8192
*.db_create_file_dest='+DATA'
*.db_domain=''
*.db_name='wxqyh'
*.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=wxqyhXDB)'
*.enable_goldengate_replication=TRUE
*.log_archive_dest_1='LOCATION=+data/wxqyh/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'
wxqyh1.instance_name='wxqyh1'
wxqyh2.instance_name='wxqyh2'
wxqyh1.instance_number=1
wxqyh2.instance_number=2
wxqyh1.thread=1
wxqyh2.thread=2
wxqyh1.undo_tablespace='UNDOTBS1'
wxqyh2.undo_tablespace='UNDOTBS2'
注：等資料庫恢復完畢後，再cluster_database設定為true。還有如果用rman duplicate必須設定如下兩個引數：
*.db_file_name_convert='/u01/app/oracle/oradata/wxqyh','+DATA/wxqyh/datafile'
*.log_file_name_convert='/u01/app/oracle/oradata/wxqyh','+DATA/wxqyh/onlinelog','/u01/app/oracle/oradata/wxqyh','+FRA/wxqyh/onlinelog'
5、恢復資料庫
5.1 用pfile檔案建立spfile
[oracle@rac1 ~]$ su - oracle
[oracle@rac1 ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.4.0 Production on Thu Apr 13 16:36:20 2017

SQL> shutdown abort
ORACLE instance shut down.
5.2 將所有的節點上pfile檔案，指向共享檔案上的spfile檔案
rac1節點:
[oracle@rac1 ~]$ echo "SPFILE='+DATA/wxqyh/spfilewxqyh.ora' " > /u01/app/oracle/product/11.2.0/dbhome_1/dbs/initwxqyh1.ora
rac2節點:
[oracle@rac2 ~]$ echo "SPFILE='+DATA/wxqyh/spfilewxqyh.ora' " > /u01/app/oracle/product/11.2.0/dbhome_1/dbs/initwxqyh2.ora
5.3 建立口令檔案
rac1節點:
[oracle@rac1 ~]$ orapwd file=?/dbs/orapwwxqyh1 password=oracle4U
[oracle@rac1 ~]$ ll /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwwxqyh1
-rw-r----- 1 oracle oinstall 1536 Apr 21 13:52 /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwwxqyh1
rac2節點:
[oracle@rac2 ~]$ orapwd file=?/dbs/orapwwxqyh2 password=oracle4U
[oracle@rac2 dbs]$ ll /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwwxqyh2
-rw-r----- 1 oracle oinstall 1536 Apr 21 13:52 /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwwxqyh2
5.4 還原控制檔案
[oracle@rac1 ~]$ sqlplus / as sysdba

9、修改日誌檔案路徑
[oracle@rac1 ~]$ sqlplus / as sysdba
SQL> set line 150
SQL> col member for a50
SQL> select * from v$logfile;
GROUP# STATUS TYPE MEMBER IS_
---------- ------- ------- -------------------------------------------------- ---

3 ONLINE +FRA/wxqyh/onlinelog/group_3.257.941900545 YES
6 rows selected.
10、開啟資料庫
SQL> alter database open resetlogs;
Database altered.
四、配置資料庫引數
1、檢視資料情況
修改引數：
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='wxqyh1';
System altered.
SQL> alter system set instance_number=2 scope=spfile sid='wxqyh2';
System altered.
SQL> alter system set thread=1 scope=spfile sid='wxqyh1';
System altered.
SQL> alter system set thread=2 scope=spfile sid='wxqyh2';
System altered.
SQL> show parameter undo_tablespace
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
undo_tablespace string UNDOTBS1
SQL> create undo tablespace UNDOTBS2 datafile '+DATA/wxqyh/datafile/undotbs02.dbf' size 100M;
Tablespace created.
SQL> alter system set undo_tablespace='UNDOTBS2' scope=spfile sid='wxqyh2';
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：根據實際情況分配日誌檔案大小，可以增加日誌組檔案
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.
2、將其他的資訊註冊到CRS裡
[oracle@rac1 ~]$ srvctl add database -d wxqyh -o $ORACLE_HOME -p +DATA/wxqyh/spfilewxqyh.ora
[oracle@rac1 ~]$ srvctl add instance -d wxqyh -i wxqyh1 -n rac1
[oracle@rac1 ~]$ srvctl add instance -d wxqyh -i wxqyh2 -n rac2
3、啟動rac1和rac2例項
[oracle@rac1 ~]$ srvctl start database -d wxqyh -o open
4、 確認例項情況
[oracle@rac1 ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.4.0 Production on Fri Apr 21 15:13:57 2017

SQL> col instance_name for a20
SQL> col host_name for a10
SQL> select instance_number,instance_name ,host_name from gv$instance;
INSTANCE_NUMBER INSTANCE_NAME HOST_NAME
--------------- -------------------- ----------
1 wxqyh1 rac1
2 wxqyh2 rac2
5、執行catclust.sql指令碼建立相關檢視
SQL> @$ORACLE_HOME/rdbms/admin/catclust.sql

6、重建 temp表空間
6.1 因為在 recover 的時候不會對temp 表空間進行recover。所以recover 後，我們要手工重建temp表空間。
[grid@rac1 ~]$ asmcmd lsof |grep temp
wxqyh wxqyh1 +data/wxqyh/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$tempfile;
NAME
--------------------------------------------------------------------------------
+DATA/wxqyh/tempfile/temp.266.941900557
+DATA/wxqyh/tempfile/temp.267.941901771
SQL> alter database tempfile '+DATA/wxqyh/tempfile/temp.266.941900557' offline ;
Database altered.
SQL> alter database tempfile '+DATA/wxqyh/tempfile/temp.266.941900557' drop including datafiles;
alter database tempfile '+DATA/wxqyh/tempfile/temp.266.941900557' drop including datafiles
*
ERROR at line 1:
ORA-25152: TEMPFILE cannot be dropped at this time
6.2 重啟資料庫再刪除原temp表空間
[oracle@rac1 oracle]$ srvctl stop database -d wxqyh -o immediate
[oracle@rac1 oracle]$ srvctl start database -d wxqyh -o open
[oracle@rac1 oracle]$ sqlplus / as sysdba

SQL> alter database tempfile '+DATA/wxqyh/tempfile/temp.266.941900557' drop including datafiles;
Database altered.
7、配置叢集監聽
7.1 配置tnsnames.ora (所有節點執行)
[oracle@rac1 ~]$ su - oracle
[oracle@rac1 ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/network/admin
[oracle@rac1 admin]$ vi tnsnames.ora
WXQYH =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.91.154)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = wxqyh)
)
)
7.2 啟動監聽
[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機測試
編輯 G:\app\oracle\product\11.2.0\client_1\network\admin\tnsnames.ora
WXQYH =
(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 = wxqyh)
)
)
執行 cmd
C:\Users\Burton>sqlplus system/oracle4U@wxqyh

---------- --------------------
1 burton
2、檢視資料庫的狀態
[oracle@rac1 admin]$ srvctl status database -d wxqyh
Instance wxqyh1 is running on node rac1
Instance wxqyh2 is running on node rac2
3、檢視資料的配置情況
[root@rac2 Desktop]# srvctl config database -d wxqyh
Database unique name: wxqyh
