Question: I am
getting the PLS-553: character set name is not recognized
error, and I need to know the location and setting for
Answer: The nls_characterset
parameter controls the character set used in the database.
The nls_characterset is normally created when the database
is created and it can be viwed with the v$nls_parameters
You can also see your nls_characterset with this query:
name = 'NLS_CHARACTERSET';
To change the nls_characterset you can execute an alter
database command, but beware that this can make your data
alter database character set
You must then bounce the database for the change to take
effect. It is also a best practice to take a full
backup before changing nls_characterset.
