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 -toption was specified with the icapmodify command, an icapmodify command without the -toption 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.
