Server Parameter File

The server parameter file (SPFILE) contains initialization parameters that Oracle Database XE uses at startup to determine the settings and run-time resources for the database. Do not attempt to edit this file with a text editor, as it is a binary file. You can change initialization parameter values by submitting ALTER SYSTEM commands with SQL Command Line. See Oracle Database SQL Reference for more information.

You can view current initialization parameter settings with the Oracle Database XE graphical user interface. See "Viewing Database Settings" for more information.
