ORA-02374 ORA-12899 ORA-02372

 用impdp导入时,报错:

ORA-02374: conversion error loading table ……
ORA-12899: value too large for column ……(actual: 31, maximum: 30)
ORA-02372: data for row: ……

原因:源库是16GDK字符集   目标库是UTF-8字符集    两库字符集不相符

解决方法:

1.修改字符集

Startup nomount;

Alter database mount exclusive;

Alter system enable restricted session;

Alter system set job_queue_process=0;

Alter database open;

Alter database character set zhs16gbk;

2.重启数据库

shut immediate;

startup

3.重新导入
