Temporary Capacity Prefetch
Because temporary capacity is pooled for the group, adjustments to the temporary capacity
balance can be made even when it is not being consumed. For performance reasons, the Group
Manager anticipates potential future use of temporary capacity and might prefetch an amount
of temporary capacity from one or more member systems. Although temporary capacity will
not be used on a member system unless the -t option was specified with the icapmodify
command, an icapmodify command without the -t option might still result in an adjustment
of the temporary capacity balance for members of the group. When this happens, the overall
temporary capacity balance for the group does not change, but there might be differences in the
allocation to individual member systems.
