RE: Question about performance of QUSLSPL vs WRKOUTQ

Thanks for the info.

Everything I found with Google pointed to paging and the first time always
takes longer blah blah blah, which I can understand.

But I was wondering why the IBM's WRKOUTQ was so much faster the first time,
obviously IBM's WRKOUTQ is doing something I am not and I was hoping to
figure out what it might be
I always tested by signing off then back on between executions and WRKOUTQ
is ALWAYS MUCH FASTER the first time

Turns out I was confused, but google sorted me out. Keywords: asynchronous
list spool. (You really should try this - it's amazing what a little
self-help can do!)

There were four or five Java example sites from IBM, and this:

I believe QUSLSPL is capable of asynchronous processing. Give it a

smaller

work area (can be a user space, but limit the amount of space you tell
the API to use. It will return to you quickly (from my experience),
with an indication that there's more data. As you consume it, ask for

more.

Computers are not intelligent. They only think they are.

I have an Output Queues with 80,000 spooled files (please don't ask
why,

I

am working on getting them cleaned up) running V5R4



If I execute WRKOUTQ TEST the processing occurs very quickly and the

list

of

spooled files appears in a few seconds



I have a program that creates a user space then runs the API QUSLSPL
to

get

the list of spooled files in the Output Queue

and after 20 minutes it is still running.



I first create a user space TSTOQENT with INITSZ(4000000)



Then

CHGVAR VAR(&OUTQNMLB) VALUE(&OUTQNM *CAT '*LIBL ')

CHGVAR VAR(&FORMAT) VALUE('SPLF0100')



CALL PGM(QUSLSPL) PARM('TSTOQENT QTEMP ' +

&FORMAT '*ALL' &OUTQNMLB '*ALL' '*ALL' )



After 20 minutes this is still running.

Am I using the wrong API?

Is there a faster method of getting a list of spooled files in an OUTQ?

I run this same program against a spooled file with a couple of
spooled files and it is very fast
