oracle修改字符集

查看oracle服务端编码：select * from sys.nls_database_parameters;
查看client编码：select * from sys.nls_session_parameters;

 

修改客户端编码：
翻开运转器进入注册表编辑
运转--》regedit
找到
HKEY_LOCAL_MACHINE/
 SOFTWARE/
 ORACLE/KEY_OraDb10g_home1
 的变量NLS_LANG的值
SIMPLIFIED CHINESE_CHINA.ZHS16GBK
改动成以下的值
SIMPLIFIED CHINESE_CHINA.AL32UTF8(效劳端编码)

 

服务端：
1. 在你的listener配置文件中增加实例信息
SID_LIST_LISTENER = 
  (SID_LIST = 
    (
SID_DESC = 
       (SID_NAME = PLSExtProc) 
       (ORACLE_HOME = F:\oracle\product\10.1.0\Db_1) 
       (PROGRAM = extproc) 
     ) 
    (
SID_DESC = 
      (SID_NAME = orcl) 
      (ORACLE_HOME = F:\oracle\product\10.1.0\Db_1) 
    ) 
  )

2. 修改oracle字符集
SQL> startup mount;
SQL> alter system enable restricted session;
SQL> alter system set job_queue_processes=0;
SQL> alter database open;
SQL> alter database character set internal_use UTF8;
SQL> shutdown immediate;
SQL> startup

oracle查看字符集
select userenv('language') from dual;
    
Oracle10G,xe修改可以采用下面的方法

connect system as sysdba ;
shutdown immediate ;
startup mount ;
alter system enable restricted session ;
alter system set JOB_QUEUE_PROCESSES=0;
alter system set AQ_TM_PROCESSES=0;
alter database open ;
alter database character set internal_use ZHS16GBK ;
shutdown immediate ;
startup ;
      
老版本可以参考

STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE CHARACTER SET UTF8;
ALTER DATABASE national CHARACTER SET UTF8;
SHUTDOWN IMMEDIATE;
STARTUP;
Database character set (UTF8) and Client character set (ZHS16GBK) are different.
Character set conversion may cause unexpected results.

Note: you can set the client character set through the NLS_LANG environment variable or the NLS_LANG registry key in
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraDb11g_home1.

1)C:\Documents and Settings\Administrator>set NLS_LANG=american_america.AL32UTF8
2)
C:\Documents and Settings\Administrator>set NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK
SIMPLIFIED CHINESE_CHINA.ZHS16GBK

注册表  HKEY_LOCAL_MACHINE->software->oracle-》key_oradb11g_home1左侧的NLS_Lang

 

SIMPLIFIED CHINESE_CHINA.ZHS16GBK与SIMPLIFIED CHINESE_CHINA.AL32UTF8
