Aha, there you are. Since I have to do a Character set conversion pretty soon, I have done a bit of research(read RTFM) on this just today.

The message means that since the character set in which the export was done and the charcter set in which the dtabase to which you are importing don't match. Data curroption can happen because of the difference in which the data is internally stored using different character sets(few are single bytes and few are multi bytes). There is something called character set scanner utlity which tell you about what will happen if the database is converted to another character set.

The character set is set at the time of creation of the database, and it can only be changed by an ALTER DATABASE .... command if and only if the charcter set is a superset of the existing characte set.

You can learn much more about all this by following this link

All,

when running an import I am seeing:

import done in WE8ISO8859P1 character set and AL16UTF16 NCHAR character set import server uses US7ASCII character set (possible charset conversion) export client uses US7ASCII character set (possible charset conversion) export server uses US7ASCII NCHAR character set (possible ncharset conversion)

My environment is set to:

rlsoprd2 [trl2]$ env | grep NLS
NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
ORA_NLS33=/oracle/product/9.0.1.3/trl2/ocommon/nls/admin/data

There is no setting in my init.ora or in the database creation scripts.

Can someone tell me where the server character set is set?

TIA, John P Weatherman
