Unanswered: character set
How can I check in what character set was created database?
select * from nls_database_parameters;
the value of the parameter NLS_CHARACTERSET shows the character set.
my next question is: is it posible to change database character set?
if yes, how?
yes it is possible.
The below link will explain in detail :
SET VALUES$ = 'WE8ISO8859P1'
WHERE NAME = 'NLS_CHARACTERSET';
It is VERY important to specify the character set name correctly. If the NLS_CHARACTERSET is updated to an invalid value, it will not then be possible to restart the database once it has been shutdown.
I would prefer that way:
In a restricted session:
# Change the database character set
alter database character set WE8ISO8859P1;
alter database national character set WE8ISO8859P1;
The new character set must be superset of the old one.
And oracle has a db scan utility, that checks, if a character set conversion would work. But I don't know, what it's name is ...
