Reminds me of my boss asking me what I knew about ODBC. "Heck, I can't even
spell it," I replied.

Anyway, he, too, was having sloooow processing getting data off of our
System i (Power 5). A couple of years later, his PC was upgraded. That
four hour job went down to minutes.

Subject: Re: Reducing ODBC connection impact

So this had me laughing out loud. I just cranked up an old 170 to assist a
customer migrating S/36 programs, OCL, and data to IBM i. As they only had
ancient QIC I needed the old girl to read that tape.

I was SHOCKED at how slow it was and I remember installing that very machine
brand new 'some years ago' and thinking how impressively fast it was back
then! Just restoring the S/36 source and OCL (about a dozen
libraries) took overnight. Including the customer's data the *SAVF I created
for them was a gargantuan ginourmous hugemoungous 375MB. Yes MB.

So while I do suspect there are some things you can do to assist a bit in
lowering the impact of these inserts, such as lowering the priority in the
COSD as others have suggested, I'm glad it's a hobby machine and not running
real production!!

I'm doing some data transfers between my 150 (running V4R5) and a Linux VM

lessen impact of the QZDASOINIT PJs in the QSERVER Subsystem. Also I'd
prefer to do that in a way that the setting(s) survive an IPL.

I still didn't get a solid grip about jobs and work management. I have a
rough idea about relative job priorities and time slices. My understanding
of subsystems is even more terse. How would you achieve the described goal?
No detailed steps necessary. Primarily I want to collect ideas how to do it

Please refrain from comments like "get a current machine" or likewise.
