在CentOS 6.4上安装Oracle 11g没有设定字符集,采用的是操作系统默认字符集:WE8MSWIN1252,将字符集修改为:AL32UTF8。

在CentOS 6.4上安装Oracle 11g没有设定字符集,采用的是操作系统默认字符集:WE8MSWIN1252,将字符集修改为:AL32UTF8。

SQL> select userenv('language') from dual;

SIMPLIFIED CHINESE_CHINA.WE8MSWIN1252

SQL> select * from nls_database_parameters where parameter in ('NLS_CHARCTERSET','NLS_NCHAR_CHARACTERSET');

SQL> select* from v$nls_parameters where parameter='NLS_CHARACTERSET';

操作过程如下:

SQL> shutdown immediate

SQL> startup

SQL> alter session set sql_trace=true;

SQL> alter system enable restricted session;

SQL> show parameter job_queue_processes;

SQL> alter system set job_queue_processes=0;

SQL> alter system set aq_tm_processes=0;

SQL> alter database open;

SQL> alter database character set INTERNAL_USE AL32UTF8;

SQL> update props$ set VALUE$='UTF8' where;

改变字符集后,原来已有的数据不会改变,,只是之后新增的数据会是新的字符集。
