About Initial NLS Parameter Values

Except in SQL Developer, the initial values of NLS parameters are set by database initialization parameters.

The DBA can set the values of initialization parameters in the initialization parameter file, and they take effect the next time the database is started.

In SQL Developer, the initial values of NLS parameters are as shown in the following table.
