二、使用DBNEWID修改DBNAME
1、查看当前的DBNAME
SQL> select name from v$database;
 NAME
 ---------
 WWL
 
2、创建参数文件
SQL> create pfile from spfile;
                             
File created.                
3、关闭数据库
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount pfile='/orasoft/product/10.2.0/db_1/dbs/initwwl.ora';
ORACLE instance started.
Total System Global Area  285212672 bytes

Variable Size              62916176 bytes
Database Buffers          218103808 bytes

4、使用NID命令更改数据库名称,将原来的WWL更改为WWL01:
[oracle@ora10g dbs]$ nid target = sys/oracle DBNAME = WWL01 SETNAME=YES;

Control Files in database:
    /oradata/wwl/control01.ctl
    /oradata/wwl/control02.ctl
    /oradata/wwl/control03.ctl
Change database name of database WWL to WWL01? (Y/[N]) => Y
Proceeding with operation

    Instance shut down
Database name changed to WWL01.
Modify parameter file and generate a new password file before restarting.
Succesfully changed database name.

5、登陆到数据库检查,发现DBNAME已经由原来的WWL修改为现在的WWL01
[oracle@ora10g dbs]$ sqlplus / as sysdba
