最近,为地市技术人员做技术支持,碰到一个很奇怪的问题,别人给他提供一个exp的dmp文件,他在本地进行imp的时候报错:IMP-00037:Character set marker unknown
报错信息如下:
C:\Users\localadmin>imp test/oracle file=C:\Users\localadmin\Desktop\jzdjxx.dmp log=C:\Users\localadmin\Deskto
p\jzdjxx.log

经测试,不是expdp导出的dmp文件,测试信息如下:

ORA-39001: 参数值无效

ORA-31619: 转储文件 "c:\jzdjxx.dmp" 无效
在linux操作系统上,查看该dmp文件的字符集,提示信息如下:
[root@docmaster ~]# cat jzdjxx.dmp |od -x|head -1|awk '{print $2 $3}'|cut -c 3-6
5353
正确的字符集标识应该是
0354
数据库中的字符集对照码验证:
SQL> select nls_charset_name(to_number('5353','xxxx')) from dual;
