Home -> Community -> Mailing Lists -> Oracle-L -> RE: DB Movement from Sun to AIX ?
Someone was posting earlier about an upgrade problem with changing character sets when switching to a new oracle database. It seemed that the import/export process was a big part of the problem, that internally, Oracle was ok about 8-bit characters in an ascii database.
I wonder if this approach would help get around that...
