Oracle 11g 转换内部编码

装Oracle 11g的时候选了gbk编码,后来想改成utf-8.

 

打开SQL Plus,登录,逐行输入下面的命令:

 

--查看Oracle数据库当前的字符集:

select userenv('language') from dual;

 

--修改Oracle数据库字符集为utf-8:

conn / 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 utf8; --zhs16gbk

 

shutdown immediate;

startup;

 

 

ps: Oracle 10g貌似安装时没有选编码的选项.
