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

、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

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.
