Import 시 imp-00008오류 해결 방법 좀 부탁드립니다.

Question

안녕하세요.
import 시 imp-00008 오류와 함께 imp.exe 응용프로그램 오류로 import 가 중지되어버림니다.
imp systm/pwd file=exp.dmp fromuser=scott touser=scott
이상한건 import 가 중지되어도 데이터 양이 적어서 그런 지는 모르지만 테이블 생성과 함께 데이터는 import 되어있다는 겁니다.
위와 같은 오류는 왜 나는 건가요?
그리고 해결방법은 없을까요?
읽어주셔서 감사하고 답변 주시면 더욱 감사하겠습니다.

Answer 1

이 메세지를 질문으로 주셨다면 좀 더 빠르게 처리했겠죠.
그리고 원래 이런 사항은 OS version, OS word size, DB version, DB word size
가 있어야 합니다. 버젼에 따라서 경우가 다르거든요.
이 사항을 자세하게 알려주시지 않아서 진행하기가 어렵네요.
어디서 exp해서 imp하는 건지요?

아래에 생락하셨던 create문은 어떻게 되나요?
그리고 exp/imp 명령까지 올려주세요. direct mode로 exp하셨나요?
alert log에 어떤 에러가 떨어지지는 않았나요?
그리고 DB의 language는 어떻게 되나요? exp할 때에 K016MSWIN949
인데 OS의 NLS_LANG은 UTF8이군요. imp하는 DB가 UTF8인가요?
KO16MSWIN949에서 한글은 2바이트 영문은 1바이트 이지만..
UTF8에서는 한글은 3바이트 영문은 2바이트?입니다.
좀 더 크게 들어가게 됩니다.
1. How does NLS affect import/export?
Import and export are client products, in the same way as SQL*Plus or
Oracle Forms, and will therefore translate characters from the database
character set to that defined by NLS_LANG. The character set used for
the export will be stored in the export file and, when the file is imported,
the import will check the character set that was used. If it is different to
that defined by NLS_LANG at the import site, the characters will be
translated to the import character set and then, if necessary, to the
database character set.

Note 15095.1 Export/Import and NLS Considerations
Note 48644.1 Identifying the Export Character Set
2. How should NLS_LANG be set when using export?
Oracle recommendeds to set the character set part of NLS_LANG environment parameter
to the same character set as the character set of the database you are exporting.
select value from nls_database_parameters where parameter='NLS_CHARACTERSET';
That way no conversion will take place and the exportfile will be created
in the same character set as the orginal database and contain ALL data from
original database (even incorrectly stored data if that would be the case).
Even if the plan is to import this into a database with a different character set
later the conversion can be postponed until the import.
3. How should NLS_LANG be set when using import?
If the source and target database have the same character set,
the character set part of the NLS_LANG should be set to that same character set
on both the export and the import.
Even if the character sets of the exporting and importing databases
are not the same the best (prefered) value to use for
the character set part of NLS_LANG on both export and import is still
the character set of the source database.
select value from nls_database_parameters where parameter='NLS_CHARACTERSET';
But setting the NLS_LANG to the character set of the target database during import
is also correct.
That way conversion only takes place once, either on export or on import.
However, the preferred place to do the conversion is between the import executable
and the target database.
4. Example: you want to go from an WE8MSWIN1252 to an UTF8 db:
(note that this is only the exp/imp example, if you want to migrate to UTF8
check Note 260192.1 for the full story )
1) double check the NLS_CHARACTERSET on the SOURCE database
select * from nls_database_parameters where parameter = 'NLS_CHARACTERSET';
and export with the NLS_LANG set to AMERICAN_AMERICA.<NLS_CHARACTERSET>
In this case we want to create a export file containing WE8MSWIN1252 data.
(This is also the setting you want to use if you take an
export as backup)
on unix this is:
$ set NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
$ export NLS_LANG
$ exp ....
on windows this is:
c:\>set NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
c:\>exp ....
2) import with the NLS_LANG set to American_america.WE8MSWIN1252 (= source NLS_CHARACTERSET)
into the new UTF8 db.
on unix this is:
$ set NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
$ export NLS_LANG
$ imp ....
on windows this is:
c:\>set NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
c:\>imp ....
The conversion to UTF8 is done while inserting the data
in the UTF8 database.
We recommend to set the NLS_LANG explicit in the current shell for unix
(-> Note 131207.1 How to Set Unix Environment Variable )
or in the dos box used for the exp or imp tool on windows.
(-> "c:\>set NLS_LANG=AMERICAN_AMERICA.<characterset of the source database>")
