ODM 11.1 and nls_Territory other than america?

Question

Has anyone got ODM working in other territory settings than AMERICA (decimal separator is dot)? It seems to crash the session quite well and none of the dbms_data_mining packages work with comma as decimal separator. Starts from the settings table where values are not recognized as valid when I try to build a model.

Answer 1

The settings table contains two columns, both of type VARCHAR2. If a numeric value is represented using a ',' (comma) as the decimal indicator, an error will occur when calling the CREATE_MODEL() procedure.
A work around would be to alter the session before calling the CREATE_MODEL() procedure, and the undo this after, as follows:
ALTER SESSION SET NLS_NUMERIC_CHARACTERS='.,';
BEGIN
DBMS_DATA_MINING.CREATE_MODEL(...);
END;
ALTER SESSION SET NLS_NUMERIC_CHARACTERS=',.';
Make sure numeric decimal values in the settings table using '.' (period) as the decimal indicator.
