oracle exp&imp之IMP-00037: Character set marker unknown

    最近，為地市技術人員做技術支援，碰到一個很奇怪的問題，別人給他提供一個exp的dmp檔案，他在本地進行imp的時候報錯：IMP-00037:Character set marker unknown
報錯資訊如下：
C:\Users\localadmin>imp test/oracle file=C:\Users\localadmin\Desktop\jzdjxx.dmp log=C:\Users\localadmin\Deskto
p\jzdjxx.log
Import: Release 11.2.0.1.0 - Production on 星期四 4月 27 11:34:16 2017

IMP-00037: 未知字符集標記
IMP-00000: 未成功終止匯入
C:\Users\localadmin>
經測試，不是expdp匯出的dmp檔案，測試資訊如下：
C:\Users\localadmin>impdp test/oracle directory=MYEXPDP dumpfile=jzdjxx.dmp logfile=jzdjxx.log

ORA-39001: 引數值無效
ORA-39000: 轉儲檔案說明錯誤
ORA-31619: 轉儲檔案 "c:\jzdjxx.dmp" 無效
在linux作業系統上，檢視該dmp檔案的字符集，提示資訊如下：
[root@docmaster ~]#  cat jzdjxx.dmp |od -x|head -1|awk '{print $2 $3}'|cut -c 3-6
5353
正確的字符集標識應該是
0354
資料庫中的字符集對照碼驗證：
SQL> select nls_charset_name(to_number('5353','xxxx')) from dual;
NLS_CHARSET_NAME(TO_NUMBER('5353','XXXX'
----------------------------------------
SQL> select nls_charset_name(to_number('0354','xxxx')) from dual;
NLS_CHARSET_NAME(TO_NUMBER('0354','XXXX'
----------------------------------------

   查詢oracle官方metalink，提示exp的dmp檔案損壞：
