Title: RE: Signal support

Alan:

        A previous post mentioned that the only way the facility could be enabled in VSE was through a special PTF that IBM had provided to one customer. Now the question is: why did he need that PTF? This whole matter seems poorly documented from the VSE side.

I'm not sure what you want me to explain.  VSE is apparently enabling itself, just like CP does, if the facility is available.  I have no idea of z/OS supports the signal or not.  It is really base hardware support since CP SIGNAL SHUTDOWN is just simulation of the signal generated when you deactivate an LPAR on machines that have the capability.
