It seems a shame to force such a significant cost associated with ICFs on users who only want to "move with the times". Also, given it's just SMF data being used here, surely there's a way for z/OS to process that without VSAM RLS and EzNoSQL (?). Perhaps they are using "ported" code, i.e. not native to z/OS, for the AI inferencing part and hence must have EzNoSQL and thus VSAM RLS. > > >W dniu 20.11.2023 o 15:01, Scott Chapman pisze: >> Just to add to the point about "or general purpose engine".

It is an onerous task for many, but perhaps there is now an impetus to do it where there wasn't previously.
