HP-UX System Administrator's Guide: Overview

iCAP You purchase (for a small price) memory, processors, or cell boards for which
you do not yet have usage rights. When you need these resources, you
purchase usage rights for them and receive codewords to activate them. From
that point on, you own those resources.
TiCAP Similar to iCAP, but the usage rights that you purchase are only temporary
(TiCAP is currently sold in 30-day increments). Your usage of the iCAP
resources is measured in 30-minute increments and when you’ve used up
the purchased time, the iCAP resources are deactivated until you activate
them again by purchasing another right-to-use codeword.
GiCAP GiCAP allows users to share rights for Instant Capacity components within
a group of servers, and provides “pooled” temporary capacity across the
group.
Tools to Administer/Configure
iCAP Commands
A series of iCAP commands allows you to interact with HP-UX to adjust the processing
capacity of a server containing iCAP hardware. The commands allow you to enter
purchased codewords to activate your rights to use the stand-by processors, or to
decrease the processing resources you are using in order to save money.
The commands to administer iCAP resources are:
