Shadow files can be used to make updates to DASD volumes "disposable", just delete the shadow file and the updates to the base DASD volume disappear. Shadow files can also be used to apply a "permanent" set of changes to the base DASD volume; usually to do this you would mark the shadow file as read-only and Hercules will automatically create an additional new shadow file to hold updates to the volume. Check out the docs at http://www.hercules-390.org/cckddasd.html Hope that helps, Regards, Charlie --- In [email protected], "Carlos Aguilera" <vitoriarest@...> wrote: > > Phil: > > > > It is probably a dumb question, could you explain to me/us what exactly are > the function of SHADOW files, I thought their function was to safeguard any > changes from affecting the real ones and they were practically disposable > but your point says otherwise.
