Instance settings can be, and usually are, overridden by session specific values.
Oracle always sends a series of alter session statements immediately after logon.
Those can be changed by setting a registry string value in the correct hive for Windows, or by setting an environment variable on Unix in your .profile.
You can also use an execute immediate statement in an after logon database trigger.
