For instance, modify some NLS settings on a session-level by the following statements

ALTER SESSION SET NLS_TERRITORY='KOREA';
ALTER SESSION SET NLS_LANGUAGE='KOREAN';
ALTER SESSION SET NLS_DATE_FORMAT='DD-MON-YYYY';
ALTER SESSION SET NLS_TIME_FORMAT='HH24:MI:SS';
ALTER SESSION SET NLS_DUAL_CURRENCY='₩';

Use the following query to fetch current NLS settings

SET PAGES 999
SET LINES 300
COL PARAMETER FOR A30
COL DATABASE FOR A30
COL INSTANCE FOR A30
COL SESSION FOR A30

SELECT ND.PARAMETER, 
       ND.VALUE "DATABASE", 
       NI.VALUE "INSTANCE",
       NS.VALUE "SESSION"
FROM
       NLS_DATABASE_PARAMETERS ND, 
       NLS_INSTANCE_PARAMETERS NI, 
       NLS_SESSION_PARAMETERS NS
WHERE
       ND.PARAMETER=NI.PARAMETER(+) AND 
       ND.PARAMETER=NS.PARAMETER(+)
ORDER BY 1;
