section on page 12-3.
Scheduler > ASAP
Rescheduling
Administrator task only. Enables the ASAP Engine (click the Enable automatic
rescheduling for ASAP sessions check box) to specify the minimum duration for
the engine to monitor sessions. You can specify the evaluation time in days, hours,
and minutes.
Based on the specified duration, the ASAP Engine only considers session sessions
to be updated if their start time is confirmed (future) from the specified duration time,
and are then rescheduled at that time.
See the “Working with
Running Sessions”
section on page 12-3.
If other sessions cancel or finish early, there is an opportunity for a previously
confirmed ASAP session to move up to an earlier time slot. ASAP does this
automatically. The Active System Manager administrator can enable or disable this
feature and the Active System Manager Welcome page displays its status. Typically,
rescheduling occurs when a session is canceled or edited to terminate early. ASAP
rescheduling uses the following rules:
• Other sessions that have not begun, and were originally scheduled in an ASAP
manner, are reviewed by the scheduler to determine if they can be advanced to an
earlier start time, thereby optimizing or “repacking” the schedule.
• The scheduler considers confirmed ASAP sessions, one at a time, to attempt to
find each an earlier time. It begins with the next session, based on the time that the
session is due to start its setup period, rather than on the session start time.
• There is a configurable value (set by the administrator) used to determine the
minimum “opportunity” time difference required before a session is considered for
rescheduling. For example, if a session is scheduled to start five minutes from
now, there would be no sense in trying to find an earlier time for it.
• Once the first candidate session is evaluated and is either changed or not
changed, the remaining candidate sessions on the list are evaluated, one at a
time, and given rescheduling opportunities based upon whether or not the prior
sessions in the list have been cancelled or rescheduled.
• Email notification of schedule changes is provided.
Note: E-mail notification is sent to the session owner, participants, and anyone
included in the TO and CC lists defined in config.properties. Mail notification can be
modified either in config.properties or by the Active System Manager administrator
on the System Properties tab.
After considering an ASAP session for rescheduling, the result is that it obtains one
of the following options:
• The same resources at the same time because no better options were available.
• Different but equivalent (typed) resources at the same time.
• A better time with either the same or equivalent resources.
Note: A session never loses a time slot, or gets a later time slot, due to ASAP
rescheduling.
