6.将cluster_database设为true :
SQL> alter system set cluster_database=true scope=spfile;
System altered.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> exit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

7. 启动所有实例：
[oracle@rac1 trace]$ srvctl start database -d RACDB
[oracle@rac1 trace]$ srvctl status database -d RACDB
Instance RACDB1 is running on node rac1
Instance RACDB2 is running on node rac2
TESTCASE2
---------------------------
用resetlogs模式重建控制文件
Test Process:
1.首先生成重建控制文件的脚本：
SQL> alter database backup controlfile to trace;
Database altered.
2. 数据库的Alert log中也会详细输出这个文件的路径和名字：
alter database backup controlfile to trace
Backup controlfile written to trace file /u01/app/oracle/diag/rdbms/racdb/RACDB1/trace/RACDB1_ora_5649.trc
3. 设置cluster_database=false：
SQL> alter system set cluster_database=false scope=spfile;
System altered.
否则，在重建控制文件的时候会报下面的错误：
CREATE CONTROLFILE REUSE DATABASE "RACDB" RESETLOGS ARCHIVELOG
*
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed
ORA-12720: operation requires database is in EXCLUSIVE mode
4. 停止所有数据库实例：
[oracle@rac1 trace]$ srvctl stop database -d RACDB
[oracle@rac1 trace]$ srvctl status database -d RACDB
Instance RACDB1 is not running on node rac1
Instance RACDB2 is not running on node rac2
5. 用resetlogs模式重建控制文件：
[oracle@rac1 trace]$ sqlplus / as sysdba

接下来需要??加其他thread，因为用resetlogs重建controlfile只是增加了thread为1的redo log：
