You can specify the value of NLS_TIMESTAMP_TZ_FORMAT
by setting it in the initialization parameter file. You can specify its value for a client as a client environment variable.
You can also alter the value of NLS_TIMESTAMP_TZ_FORMAT
by changing its value in the initialization parameter and then restarting the instance. To alter the value during a session use the ALTER SESSION SET
statement.
Note:
The value of this initialization parameter NLS_TIMESTAMP_TZ_FORMAT
is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG
client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.
