Alter other session parameter

Hi

Oracle has Alter System command through which an administrator can modify all logged-in session's parameters.
Oracle has Alter Session command through which one can modify one's own session's parameters.

Is there is a way in through which an administrator can modify any particular session's parameters (apart from his/her own session) ?
Why has this option not been provided ?

Thanks in advance

AFAIK you cant alter session other than yours.

Only Oracle knows... It may be a good suggestion for Oracle to include this feature in the future release :)
