oracle11g 修改字符集 修改为ZHS16GBK

1.cmd下,cd到oracle数据库软件的服务器端如：D:\DevSofts\Oracle\app\oracle\product\11.2.0\server\bin

2.输入set ORACLE_SID=你想进入的数据库的那个sid

3.输入 sqlplus /nolog

4.将数据库启动到RESTRICTED模式下做字符集更改： 

SQL> conn/as sysdba 

Connected. 

SQL> shutdown immediate; 

Database closed. 

Database dismounted. 

ORACLE instance shut down. 

SQL> startup mount 

ORACLE instance started. 

Total System Global Area  236000356 bytes 

Fixed Size                  451684 bytes 

Variable Size             201326592bytes 

Database Buffers           33554432bytes 

Redo Buffers                667648 bytes 

Database mounted. 

SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION; 

System altered. 

SQL> ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0; 

System altered. 

SQL> ALTER SYSTEM SET AQ_TM_PROCESSES=0; 

System altered. 

SQL> alter database open; 

Database altered. 

SQL> ALTER DATABASE CHARACTER SET ZHS16GBK; 

ALTER DATABASE CHARACTER SET ZHS16GBK 

* 

ERROR at line 1: 

ORA-12712: new character set must be a superset of old characterset 

 

提示我们的字符集：新字符集必须为旧字符集的超集，这时我们可以跳过超集的检查做更改： 

SQL> ALTER DATABASE character set INTERNAL_USE ZHS16GBK; 

Database altered. 

SQL> select * from v$nls_parameters; 

略 

19 rows selected. 

重启检查是否更改完成： 

SQL> shutdown immediate; 

Database closed. 

Database dismounted. 

ORACLE instance shut down. 

SQL> startup 

ORACLE instance started.
