Re: Proper usage of MSGQs and DTAQs, etc.

I agree that there should be a good link, but I'm not aware of it.

In the early System/38 days, we started to use message queues for items
that required notification/interruption so that we could move in-line
interactive to a batch background task, but message queues were not great
performers.  Frequently the overhead of sending the message outweighed the
benefit of doing the specified batch function in-line.  As a result of
this, IBM brought out data queues, which gave us the same basic function as
message queues, but with less overhead, and message like details.
Consequently for stuff that is machine readable only, you're better to go
with DTAQ's, not MSGQ's.

I'm sure there has to exist some guides to using MSGQs and DTAQs for
program-to-program communication the proper, industrial-strength, scalable
way, but I can't find it. I would have thought that somewhere IBM would
have a book explaining their usage in a non-language-specific manner.
Anybody got a good link?
