oracle设置字符集

/////////////客户端、服务端字符集的查看后面补上

1 修改服务器的字符集，直接修改prop$表，将NLS_CHAR字符集改为ZHS16GBK

UPDATE PROPS$ SET VALUE$='ZHS16GBK' WHERE NAME='NLS_CHARACTERSET';

2 修改客户端字符集 regedit/nls_lang = AMERICAN_AMERICA.ZHS16GBK (具体路径google)

3 oracle字符集修改的地方很多，只是修改了上面的地方，会报各种奇怪的错，继续下面的修改

则进行如下处理：

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;

COL VALUE NEW_VALUE CHARSET

SELECT VALUE FROM NLS_DATABASE_PARAMETERS WHERE PARAMETER='NLS_CHARACTERSET';

COL VALUE NEW_VALUE NCHARSET

SELECT VALUE FROM NLS_DATABASE_PARAMETERS WHERE PARAMETER='NLS_NCHAR_CHARACTERSET';

--INTERNAL_USE是没有写在文档中的参数，用以强制完成字符集一致化

ALTER DATABASE CHARACTER SET INTERNAL_USE &CHARSET;

ALTER DATABASE NATIONAL CHARACTER SET INTERNAL_USE &NCHARSET;

SHUTDOWN IMMEDIATE;

STARTUP;
