Enable selective reclaim to prioritize and reclaim resources based on the importance of
running tasks and sessions.
About this task
By default, the system reclaims resources as quickly as
possible, with minimum overhead. You can modify this behavior so that the system considers the
relative importance of running work and reclaims resources from less important sessions first.
Procedure
-
From the cluster management console,
click .
-
Select an application profile to edit and expand the General Settings
section.
-
Specify Enable Selective Reclaim = true. By default, selective reclaim
is set to false.
From all the suitable hosts in the consumer, consider session importance (preemption rank or
session priority) and preemption criteria to determine which resource to reclaim.
If Enable Selective Reclaim = false, which is the default behavior. From
all the suitable hosts in the consumer, pick a host at random and reclaim a resource from that host.
Session importance (preemption rank or session priority) and preemption criteria determine which
slot on the host is chosen.
