ORA-01843: 无效的月份，执行sql语句更改为美国语言后仍然失败的解决办法
ORA-01843: 无效的月份
失败的 sql 为:XXXXXXXXXXXXXXXX
执行sql语句更改为美国语言后仍然失败，
ALTER SESSION SET NLS_DATE_LANGUAGE='AMERICAN';
结果是注册表的问题，优化后多余的语言被清理掉了，所以，要修复注册表
将下面的文件复制保存为注册表文件.reg双击导入注册表。
windows server 2005 系统时区文件 Time Zones.reg的文件内容，适用于windows server 2008 r2
我是从2005中导出来的，然后导入2008 结果正常，希望对大家有用
注册信息存在系统的三个不同的地方，现整合为一个文件，省掉一些麻烦。
