3、关闭数据库并在一个节点启动到mount
[oracle@rac01 ~]$ srvctl stop database -d orcl
[oracle@rac01 ~]$ cd /tmp/
[oracle@rac01 tmp]$ ls -l pfil*
-rw-r--r-- 1 oracle oinstall 1374 May 4 17:51 pfile.ora

SQL> startup mount;
SQL> quit
4、修改数据库dbname为db11g
[oracle@rac01 dbs]$ nid TARGET=SYS/oracle@orcl DBNAME=db11g SETNAME=Y
DBNEWID: Release 11.2.0.4.0 - Production on Thu May 4 17:57:01 2017

Instance shut down
Database name changed to DB11G.
Modify parameter file and generate a new password file before restarting.
Succesfully changed database name.
DBNEWID - Completed succesfully.
5、尝试startup无法启动，因为在参数文件中记录的dbname仍然是orcl
[oracle@rac01 dbs]$ cat initorcl1.ora
SPFILE='+DATA/orcl/spfileorcl.ora'
[oracle@rac01 dbs]$ sqlplus / as sysdba

ORA-01103: database name 'DB11G' in control file is not 'ORCL'
6、修改pfile中的dbname参数，修改为新的dbname
[oracle@rac01 dbs]$ vi /tmp/pfile.ora
change *.db_name='orcl'
to *.db_name='db11g'
7、使用pfile启动
[oracle@rac01 dbs]$ sqlplus / as sysdba

8、创建spfile，需指定路径，因为spfile在ASM磁盘中，否则会在本地生成一个spfile
SQL> create SPFILE='+DATA/orcl/spfileorcl.ora' from pfile='/tmp/pfile.ora';
File created.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
9、重启数据库
SQL> startup

10、修改群集参数为true
SQL> alter system set cluster_database=true scope=spfile;
System altered.
SQL> select dbid,name,open_mode,activation#,created from v$database;
DBID NAME OPEN_MODE ACTIVATION# CREATED
---------- --------- -------------------- ----------- ---------
1470887377 DB11G READ WRITE 1470884038 14-MAR-17
11、重建密码文件
[oracle@rac01 dbs]$ orapwd file='$ORACLE_HOME/dbs/orapworcl1' password=oracle entries=10 force=y
[oracle@rac01 admin]$ lsnrctl status

12、修改tnsname.ora文件的service_name为db11g
[oracle@rac01 dbs]$ cd ../network/admin/[oracle@rac01 admin]$ vi tnsnames.ora
