Hi Berry, It would seem that we think along similar lines - I went to the Service Guide and decided that SYSTEM NETID would be a replacement-maintained par t - but SES didn't seem very impressed when I followed the, 'replacement' process in, 'Procedures for Local Service and Modifications' in Chapter 6
... (basically I just, 'followed the bouncing ball' - I won't (yet) put u p the individual steps that I took here but I can if that level of detail becomes of interest). I suspect that maybe SES doesn't actually know about SYSTEM NETID - I'm f ar from claiming to be any kind of SES expert (I have a working acquaintance and have modified a few PPF's in my time but never delved too deeply) - b ut when I use VMFINFO to dig out information on (say) DMSIUX it feeds me bac k useful stuff but ask it about, 'SYSTEM' (in Serviceable Parts) / Part Fil e Name / Status of Object(s)) and it knows about, 'GSUBLLIB.SYSTEM' but nothing that looks like SYSTEM NETID. However, there IS a SYSTEM NETID on the BASE2 disk - which kind-of sugges ts that perhaps SES DOES know about it - hmm. I need to learn a bit more ab out how the SES Inventory works so that I can confidently interrogate the database and understand the answer when I ask it, 'Do you know about this component or not?' You are, of course, quite correct that SYSTEM NETID is trivial and any self-respecting installation will have appropriate procedures for maintaining trivia such as this outside of SES - however my current quest is NOT practical or pragmatic - it's a quest for knowledge ... initially simply, 'What's the IBM-recommended way of doing this?' (on the basis tha t this is the safest way to avoid being burned by any future IBM changes to maintenance processes) but now I'm also beginning to ask, 'Hey - how DO I get SES to do this?' (on the basis that, perhaps, ideally, SES should be managing ALL system changes - even the trivial stuff). After all, why re-invent the wheel and add my own software management layer if I can get the standard one to do the work for me? Thanks again for the feedback - if you should know for-sure how to ask SE S if it 'groks' SYSTEM NETID then I'd appreciate a hint <g>. Jeff
