Oracle11g: how I change character set to AL32UTF8?
628367Nov 19 2009 — edited Feb 22 2012Hi, a software is requiring to have a database with AL32UTF8 character set.
For what I understand I have an instance of db with
nls_language=american
I tried:
SQL> alter database character set AL32UTF8;
alter database character set AL32UTF8
*
ERROR at line 1:
ORA-12712: new character set must be a superset of old character set
what's wrong? How can I achieve this?
Thanks a lot.
