no, v$parameter and v$system_parameter have the same structure. The difference between the 2 is that some (but not all) of the settings in v$parameter reflect the current SESSIONS setting of that parameter whereas v$system_parameter shows the 'default' setting for a value given a new session. Over time, all elements in v$parameter will show the session setting.
