<snip> Could we use SYSTEM boost to make the process of shutting down the CICS region and restarting them? </snip>
That would not be an appropriate use of the shutdown boost. Shutdown boost is for shutting down the entire system. <snip> Note that IBM also has a separate feature called "System Recovery Boost Upgrade" which is unrelated to "System Recovery Boost" ... it is more like CUoD. That is a paid feature and gives a 6 hour boost in processing speed. </snip> "Gives a 6 hour boost in processing speed" is not a good characterization of System Recovery Boost Upgrade. It does not do so. Each activation (and the upgrade covers multiple) gives you a 6 hour window during which additional processors can be applied to each LPAR when that LPAR is starting up or shutting down. It is during the startup and the shutdown that the additional processors can participate.
