Dear Sir,

I have received an export log file which starts like
Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options
Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set
server uses UTF8 character set (possible charset conversion)

Q1.What does "possible charset conversion" mean?
Q2.How do we make out what is the national language character set of the specified server of which the export is done?

Thanks
Shachi

Q1. It means that source and target (N)character code points may not be the same (and in this case they are not)

Q2. Don't understand the question. You can see national language character set in NLS_DATABASE_PARAMETERS view.

Regards
Michel

I meant how we make out the national characterset before the import of the dump.

Isnt this information required for the creation of user and choosing the right characterset settings so that after the import the data is intact?

Sorry I don't understand "make out".

No this is a DATABASE parameter.

You can't choose the character set in the final database, it is fixed.

I have not created the database and i dont want character mismatch between the exported data user and the new user where i want to import the data.

For this i hope both the charactersets are required?

Sorry I didn't see your export, I thought you were importing.

You have to set your NLS_CHARACTERSET (or NLS_LANG) and NLS_NCHAR_CHARACTERSET environment parameters to the same values as the database if you don't want any conversion.

Regards
Michel
