Oracle11g: how I change character set to AL32UTF8?

628367Nov 19 2009 — edited Feb 22 2012
Hi, 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.

I've finally determined the cause of all my troubles. It turns out that if Tomcat is running as a service on Windows 2000, it can't access the console and as a result it can't call external programs. I turned off the service temporarily and started up the stand-alone Tomcat application and my JSP pages work without a hitch. Unfortunately, I think they'll want to keep Tomcat as a service, so I haven't completely solved all of my problems. So does anyone know of a way to execute external programs using Runtime.exec() while running Tomcat as a service? Thanks.

the notepad called by your jsp is the NOTEPAD program under the server part,

so ,under client part , there will be no response, because the logic process of the jsp is disposed under server part.

BUT
how to call a native function of client part under Browser/Server structure ?
i don't know, for example: in an web page (jsp / servlet / applet) to call the
"Outlook Express\\msimn.exe" , which is useful in many B/S applications.
This puzzled me a lot.

Hope some one can give an answer.
