以下是簡要介紹給叢集資料庫新增控制檔案的過程。
----新增控制檔案：
---檢視當前的控制檔案：
SQL> show parameter control_files
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_files string +DATA/prod/controlfile/current
.264.927167493, +OCR_VOTE/prod
/controlfile/current.256.92716
7497
#可以看到有兩個日誌檔案：

---關閉資料庫並將一個節點啟動到nomount狀態：
[oracle@node1 ~]$ srvctl stop database -d prod -o immediate
PRCC-1016 : prod was already stopped
[oracle@node1 ~]$ srvctl status database -d prodInstance prod1 is not running on node node1
Instance prod2 is not running on node node2
[oracle@node1 ~]$
#已經關閉資料庫：

--開啟到nomount狀態：
[oracle@node1 ~]$ sqlplus / as sysdba

---備份引數檔案：
SQL> create pfile='/home/oracle/initprod.ora' from spfile;
File created.

---利用RMAN 建立控制檔案：
[oracle@node1 ~]$ rman target /

RMAN>
RMAN> restore controlfile to '+DATA' from '+DATA/prod/controlfile/Current.264.927167493';

Starting restore at 06-NOV-16
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=33 instance=prod1 device type=DISK

channel ORA_DISK_1: copied control file copy
Finished restore at 06-NOV-16
RMAN> exit

Recovery Manager complete.

---在Grid使用者使用ASM檢視控制檔案：
cd DATA/prod/CONTROLFILE
[grid@node2 ~]$
[grid@node2 ~]$ asmcmd
ASMCMD>
ASMCMD> cd DATA/prod/CONTROLFILE
ASMCMD> pwd
+DATA/prod/CONTROLFILE
ASMCMD> ls
Current.264.927167493
current.269.927211623
ASMCMD>
#已經新增一個。

---修改引數檔案，使其新增控制檔案：
SQL> col HOST_NAME for a20
SQL> select INST_ID,HOST_NAME,STATUS from gv$instance;
INST_ID HOST_NAME STATUS
---------- -------------------- ------------
1 node1 STARTED

SQL>
--修改引數檔案的控制檔案引數：
SQL>
SQL> alter system set control_files=
2 '+DATA/prod/controlfile/Current.264.927167493',
3 '+DATA/RACDB/controlfile/current.269.927211623',
4 '+OCR_VOTE/prod/controlfile/current.256.927167497'
5 scope=spfile;
System altered.
SQL>

--退出：
SQL> exit

---啟動資料庫：
[oracle@node1 ~]$ srvctl start database -d prod
PRCC-1014 : prod was already running
[oracle@node1 ~]$

---檢視新的控制檔案：
--節點1：
SQL> show parameter control_files
NAME TYPE VALUE

.264.927167493, +DATA/racdb/co

3, +OCR_VOTE/prod/controlfile/
current.256.927167497
