'Should' is a strong word here. I don't think that I'd be relying
on it. Perhaps I'm pessimistic?
Or, perhaps, there was more information that was not provided as it
was not relevant to the problem at hand (x-webobjects-request-id
values not as unique as expected) and yet which my MD might deem
confidential intellectual property. This approach is adequately
sound for me.
and then generate a response (without blocking on database i/o) to
the effect that database congestion may be in progress, that their
request is being processed, any database updates may or may not be
committed but will be committed at most once.
Given that you've put rather bluntly that long request
configuration won't work for you,
Bluntly? Well yes I suppose, but .... you should have seen the
drafts I discarded!
I'm not sure how you expect to achieve this across multiple
instances without building the infrastructure yourself.
Which is what I did ... multicast datagram socket.

What I am doing is reporting a bug in the WebObjects API adaptor,
with the circumstances as how how I encountered it. It might be
possible to deduce, for example, that the application list etc
(see config.c in the Adaptors project) is in shared memory, while
uniqueID_counter (see transaction.c) is not in shared memory, but
should be, if we cared.
Anybody reading this list who is interested in the adaptor?
Patches welcome!
Cough. Yes. I dare say they are.
