Re: MIDRANGE-L Digest, Vol 16, Issue 828

In our company we replaced many of the "month end" with triggers that do "the job" for each transaction, so the month end becomes a lot faster. As a bonus, you can get current info any day. Very good to make your computer look more modern.

But, and it is a big BUT, the change is not simple.

Thanks Rob

First, The machine in question is a Power 8 V7R2

2nd, our main periodic processing jobs are big monolithic RPG programs
that do not easily lend themselves to "parallelization" efforts.
(actually I was told that it can't be done as each such job is
executed by one processor only and splitting such a job into 2-3 sub-jobs
is a splitting headache )

IBM's (and others) investigation into these jobs found them to be
"Processor bound"

Hence, if we want to see a performance gain with the new machine and remain
in P10 class then a Power9 processor is called for.

I'm thinking the Power 8's are plenty powerful enough with no reason to
wait.

Sibley went in the direction of system design and high performance
interconnects, while mentioning the introduction of Power9 servers would
come late in 2017, with IBM i versions unavailable until early 2018.

And my totally baseless prediction is that 7.1 will not be supported on
it. Think about it. 7.1 hits end of support 4/30/2018 and the above says
"IBM i versions unavailable until early 2018". At minimum, it would take
a new TR of 7.1 and IBM says there will be NO new TR's for 7.1.
<snip>?IBM i 7.1 TR11 is the final Technology Refresh (TR PTF and TR PTF
Group) for IBM i 7.1.</snip>
Sure, IBM skated around this a little for some Power 8 stuff with Resave S
but no matching TR but don't bet your business on that happening again
with 7.1.

Hello Guys

I might have a budget allocation for a new IBM i machine *this year*

does anybody know when P9 will be available?
(I have a vague recollection of Q3-Q4 / 2017).

TIA
Gad
