impdp导入时遇到报错
ORA-02374: conversion error loading table "UCR_PARAM"."SEC_OP_AUTHOR_ATTACH"
ORA-12899: value too large for column GRANT_TYPE (actual: 3, maximum: 1)
ORA-02372: data for row: GRANT_TYPE : 'O '
导入日志如下：

使用export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK把导出端和导入端的环境变量重新加载下再导入
这次导出使用的dblink导出，中间库的字符集跟目标库和源库都不一样
SQL> select * from nls_database_parameters;

本来使用的中间库dblink，不入库落地到中间库的服务器，在scp到目标端impdp的方式。
虽然没入库，但是中间库的字符集不一样还是导致了ORA-02374 ORA-12899 ORA-02372的错误
现在只有绕过中间库，或者在重建一个gbk的中间库。
