linux下修改oracle10g编码

su - oracle 转换用户
sqlplus /nolog  不连接任何数据库
conn 用户名/密码 as sysdba 用sysdba 登陆

shutdown immediate 关闭（shutdown Abort强行关闭）
startup mount 启动
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;
ALTER DATABASE NATIONAL CHARACTER SET INTERNAL_USE AL16UTF16; 
shutdown immediate
startup


之后会发现已经生效:
SQL> select name,value$ from props$ where name like '%CHARACTER%';
NAME
------------------------------
VALUE$
------------------------------------------------------------------------------
NLS_NUMERIC_CHARACTERS
.,
NLS_CHARACTERSET
ZHS16GBK
NLS_NCHAR_CHARACTERSET
AL16UTF16
