I am trying to import a dump and I get the following message:
Export file created by EXPORT:V10.02.01 via conventional path
import done in US7ASCII character set and AL16UTF16 NCHAR character set
import server uses WE8MSWIN1252 character set (possible charset conversion)
export client uses EL8ISO8859P7 character set (possible charset conversion)
...
Is it possible to change NLS and how? Do I have to install Oracle XE from scratch?
