RE: Message about character sets on EXPORT - should I worry?

FYI, recently we upgraded our satabases from 7.3.4.5 to 8.1.7. I forgot to specify WE8ISO8859P1 when I created a new database so it was created as US7ASCII. I loaded that database with an import that had been done from a WE8ISO8859P1 database. Oracle had me trash that db and start over from the beginning. They said the data would be corrupted doing an import from a WE8etc. database into US7ASCII.

Actually you won't have to do a characterset conversion because WE8ISO8859P1 is a superset of US7ASCII. But this message is just telling you that it might do a conversion . Set the characterset to WE8ISO8859P1 on the server at the command line prompt and everything should go OK.

HTH,
