when profile idle time is exceded, session status will change to "SNIPED", even for "SNIPED" status session, system will consume the session space, In our system there is a limited number of sessions available,

in our system, once the session status changes to sniped then after 2 hours then it will be cleared from V$SESION, as per my understanding, this will be controled by DBA Parameter,

Could any one advice me, whats the parameter.

( OR )

Is there is a way to clean up the sniped sessions so that new users can be allowed to login without
hitting the max. number of sessions problem?

Thank you.
