To make Oracle Forms 6i able to connect to Oracle XE 10g I set the database
character set to UTF8.
Steps to do are as follows:
First I shutdown the database:
SQLPLUS>shutdown immediate
Then I start the database in restrict mode:
SQLPLUS>startup restrict
Then I change the database character set as follows:
SQLPLUS>ALTER DATABASE CHARACTER SET INTERNAL_USE UTF8;
Then I shutdown the database:
SQLPLUS>shutdown immediate
Then I start the database in normal mode:
SQLPLUS>startup
After this my colleague was able to connect to the Oracle XE database
through Forms 6i.
