Back To Machines

The ‘“Principle” Of Sufficient Disgust’ kicked in - as it so often does - about a year ago.
The issues outlined in that original posted revolved around having only one way to identify a machine. My code accepted only one type of specification for a machine:
By the way Ewelme is a real place with one of those quintessentially English names few people can pronounce.
Getting to the hallowed state of being able to construct a string like that was a pain. Hence my frustration. And you could probably tell I was frustrated from the original post.
So today I’ve enhanced the code to accept the following additional forms of syntax:
To be fair, Case 1 is a rarity; Most people, if they know the 5-digit serial number, know the plant number.
Case 2 I see quite a bit in customers’ machine diagrams. It, I think, relates to SCRT and there is at least one place in SMF 70 where the 4-digit variant appears. It seems silly to be using it when we have the full plant and serial numbers in SMF 70.
Case 3 is probably the most user-friendly. I see diagrams and descriptions where customers say or depict ‘We call the machine with SYSC on it “Ewelme A”’.
Previously, I would take whichever of the previous 3 description types I got and manually work with the data to figure out the plant and 5-digit serial number (and use that in e.g. VPD look ups, as well as relating it to the machine’s human-friendly name).
I don’t think I ever got it wrong but it sure was tedious.
Now, with the new code you use all those semantics, plus the original one - because I automated it.
Here’s how I did it:
Really very simple.
There is one (obscure) catch: If I specify
The upshot is I won’t be quite so desperate to get your machine serial numbers, though I’ll happily take them. I don’t know how you refer to your machines but now I have a foolproof way of handling them.
One more thing: I recently had an engagement where a customer moved LPARs from one machine to another. My code doesn’t handle that at all; We just have to be careful.
And if you listen carefully to this you will hear the refrain “Back To Machines”.
