HP 16-port SCS Installation Instructions Manual page 35

The following examples show the interaction between share mode and access levels.
Session sharing examples
These examples illustrate session sharing and preemption for one port and two users. Assume this port is currently in
use by the session originator (SO). Another user, the requesting user (RU), wants to connect to the same port. For
simplicity, also assume that if RU is allowed to connect, it will not exceed the maximum allowable number of sessions
per port or sessions per SCS.
Example 1—The access level of SO is higher than the access level of the RU.
Share mode = Query<
SO is connected non-exclusively.
SO will be prompted to approve sharing the connection.
If SO approves, then RU will be connected to the port.
If SO does not approve, then RU will not be connected to the port.
Share mode = Query<
SO is connected exclusively.
RU will not be connected to the port.
Share mode = Disabled or Auto
RU will not be connected to the port. (In this case, it does not matter whether SO is connected exclusively or
non-exclusively.)
Example 2—The access level of the RU is equal to or higher than the access level of the SO.
Share mode = Disabled<
-or-
SO is connected exclusively.
RU is prompted with preemption choices E, N, and D.
If RU replies with E, then SO will be preempted or disconnected and RU will be connected exclusively to the
port.
If RU replies with N, then SO will be preempted or disconnected and RU will be connected non-exclusively
to the port.
If RU replies with D, SO will remain connected and RU will not be connected to the port.
Share mode = Auto or Query<
SO is connected non-exclusively.
RU is prompted with preemption choices E, N, S, and D.
If RU replies with E, then SO will be preempted or disconnected and RU will be connected exclusively to the
port.
If RU replies with N, then SO will be preempted or disconnected and RU will be connected non-exclusively
to the port.
If RU replies with S and Share Mode = Auto, SO will remain connected and RU will be connected to the
port.
If RU replies with S and Share Mode = Query, SO will be prompted to approve sharing the connection.
If SO approves, RU will be connected to the port.
If SO does not approve, RU will not be connected to the port.
If RU replies with D, SO will remain connected and RU will not be connected to the port.
Example 3—Ending shared sessions
In a shared session, if the SO quits the session, the next user sharing the session will become the SO. If the SO is
logged out by another user, all sessions that are shared with the SO will be terminated, as well as the SO session.
