NLS_LANG should be set on client, either UNIX environment variable or NT registry entry.

I don't think there's a way to force client to use a particular character set. This is the whole point of NLS, I think. Server should not care what language/character set client uses, and vice versa.

Gerardo,

Thanks for your help. I need little more clarification: When we change the database character set from US7ASCII TO UTF8 Do this will only affects for the server database and client can still export in different character set as per setting of NLS_LANG on their machine......
If i want to force clients to use NLS_LANG of server database how can i set some parameters on server .....
NLS_LANG is set as environment varable but if i want to add entry in init.ora we have parameter NLS_LANGUAGE and NLS_TERRITORY...but how can we specify the chacter set in init.ora file........ I know i am asking some silly questions but i am totally confused with oracle docs.

Thanks

Harvinder,

try setting NLS_LANG=AMERICAN_AMERICA.UTF8, then doing the export.

If NLS_LANG is not set, the default is US7ASCII as you experienced.

Refer to MetaLink Note 48644.1 and Note 15095.1

Gerardo,

The trick works for me also but when i try to export it shows as:

Connected to: Oracle8i Enterprise Edition Release 8.1.7.0.0 - Production With the Partitioning option
JServer Release 8.1.7.0.0 - Production
Export done in US7ASCII character set and US7ASCII NCHAR character set server uses UTF8 character set (possible charset conversion)

Do we are able to change character set or our existing data is still using US7ASCII. Thanks

Try this procedure:

The extra db bounce did the trick for me. Don't ask me why. I think I found it on MetaLink or opened a TAR.

Hi,

We are planning to change out database charater set from US7ASCII to UTF8 and we followed folowing steps as specified in metalink... but still when i see the trace of controlfile it shows character set as US7ASCII..
