Oracle Import problem caused by different character sets I'm trying to import an Oracle 11 export into Oracle 11 XE.

I get the following messages:


  import in XE fehlerhaft import done in WE8MSWIN1252 character set and
  AL16UTF16 NCHAR character set
  import server uses AL32UTF8 character set (possible charset conversion)


Any ideas, how I can import this dump into Oracle 11 XE ?

Edit:

Given a table

CREATE TABLE BDATA.Artikel(
    Key                   VARCHAR2(3)  NOT NULL,
    Name                  VARCHAR2(60) NOT NULL,
    Abkuerzung            VARCHAR2(5)  NOT NULL
);


I get errors like this

IMP-00019: row rejected due to ORACLE error 12899
IMP-00003: ORACLE error 12899 encountered
ORA-12899: value too large for column "BDATA"."ARTIKEL"."ABKUERZUNG" (actual: 6, maximum: 5)
Column 1 ABL
Column 2 Aufbewahrungslösung
Column 3 AfbLö


Some rows are missing from the import.
If that is the actual DDL you are using to create the table, you could use the NLS_LENGTH_SEMANTICS parameter.  If you set that to CHAR rather than the default of BYTE, a VARCHAR2(5) will be allocated enough space to store 5 characters in the database character set (potentially up to 20 bytes) rather than 5 bytes (which could allow just 1 character).

Unfortunately, changing the NLS_LENGTH_SEMANTICS probably won't be terribly helpful if you're relying on the import process to create the table-- the dump file will inherently add the CHAR or BYTE keyword so it would actually issue the statement

CREATE TABLE BDATA.Artikel(
    Key                   VARCHAR2(3 BYTE)  NOT NULL,
    Name                  VARCHAR2(60 BYTE) NOT NULL,
    Abkuerzung            VARCHAR2(5 BYTE)  NOT NULL
);
