在Linux下修改oracle的字符集(2)

因为是双向流复制，要一致的表结构，同样，把开发部服务器导入过来，乱码

考验时候来了，这次解决更快些，有些地方还得注意一下，记录一下。

先查看一下

SELECT * FROM PROPS$; 实践证明：不要在这个SQL语句中 update props$ ....确实难搞。

select * from v$nls_parameters;

Select * from NLS_DATABASE_PARAMETERS;

SELECT DISTINCT (NLS_CHARSET_NAME(CHARSETID)) CHARACTERSET,

DECODE(TYPE#, 1,

DECODE(CHARSETFORM, 1, 'VARCHAR2', 2, 'NVARCHAR2', 'UNKOWN'),

9,

DECODE(CHARSETFORM, 1, 'VARCHAR', 2, 'NCHAR VARYING', 'UNKOWN'),

96,

DECODE(CHARSETFORM, 1, 'CHAR', 2, 'NCHAR', 'UNKOWN'),

112,

DECODE(CHARSETFORM, 1, 'CLOB', 2, 'NCLOB', 'UNKOWN')) TYPES_USED_IN

FROM SYS.COL$

WHERE CHARSETFORM IN (1, 2)

AND TYPE# IN (1, 9, 96, 112);

我的正常的情况是：

1 ZHS16GBK CHAR

2 AL16UTF16 NCLOB

3 ZHS16GBK VARCHAR2

4 AL16UTF16 NVARCHAR2

5 ZHS16GBK CLOB

6 AL16UTF16 NCHAR

1进入 /etc/profile/ 编辑vi profile

添加NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"

2 source profile

3 进入oracle主目录 编辑vi .bash_profile, source .bash_profile

重新进入PL/SQL，查看的是乱码，重校导入数据就OK了。
