使用expdp時(shí)，遇到”O(jiān)RA-39002、ORA-39070......”連續(xù)報(bào)錯(cuò)。

1、  遇到的問(wèn)題

C:\Users\Administrator>expdp 'sys/system as sysdba' directory=backup full=y dumpfile=fullexp.dmp logfile=fullexp.log;

    Export: Release 10.2.0.3.0 - Production on Wednesday, 18 April, 2012 12:13:15

    Copyright (c) 2003, 2005, Oracle. All rights reserved.

    Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production

    With the Partitioning, OLAP and Data Mining options

ORA-39002: invalid operation

ORA-39070: Unable to open the log file.

ORA-29283: invalid file operation

ORA-06512: at "SYS.UTL_FILE", line 475

ORA-29283: invalid file operation

2、  問(wèn)題解決

Google了一下，發(fā)現(xiàn)了問(wèn)題原因：

（1）、查看directory 對(duì)象

SYS@ tsid > select * from dba_directories;

OWNER DIRECTORY_NAME            DIRECTORY_PATH

----- ------------------------- ------------------

SYS   BACKUP                    E:\oradata\backup

而操作系統(tǒng)上，E:\oradata下，沒(méi)有backup目錄。因?yàn)槟夸洸淮嬖?，所以?huì)出現(xiàn)” ORA-39070: Unable to open the log file.”錯(cuò)誤。

   （2）、創(chuàng)建”E:\oradata\backup”目錄，或者修改directory 對(duì)象，問(wèn)題解決。

3、導(dǎo)致問(wèn)題出現(xiàn)的潛在原因。

   Oracle 10g 下創(chuàng)建directory對(duì)象，即使所引用的目錄不存在，該命令也可以正常執(zhí)行，這樣就容易造成這樣的錯(cuò)誤。
