使用expdp時,遇到”ORA-39002、ORA-39070......”連續報錯。
1、 遇到的問題
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、 問題解決
Google了一下,發現了問題原因:
(1)、查看directory 對象
SYS@ tsid > select * from dba_directories;
OWNER DIRECTORY_NAME DIRECTORY_PATH
----- ------------------------- ------------------
SYS BACKUP E:\oradata\backup
而操作系統上,E:\oradata下,沒有backup目錄。因為目錄不存在,所以會出現” ORA-39070: Unable to open the log file.”錯誤。
(2)、創建”E:\oradata\backup”目錄,或者修改directory 對象,問題解決。
3、導致問題出現的潛在原因。
Oracle 10g 下創建directory對象,即使所引用的目錄不存在,該命令也可以正常執行,這樣就容易造成這樣的錯誤。
