RE: [WEB400] An instance of QZSRCGI won't end after ENDTCPSVR

[michael.bailey@xxxxxxxxxx]

Thanks for getting back to me Bob, I've been working with the AS/400 since 
it was first released and my first rule of support has always been to 
gather as much information as possible before cancelling a crashed app. as 
you may not get a chance until it happens again. Have I ever bothered to 
check exactly which procedure and line number that the CGI app. is sitting 
on - NO! Could be because I'm just not myself at 4am! 

You're right though, the CGI program doesn't set on LR. However, in 2 
years it's never been a problem so perhaps Apache has unearthed something 
that the old server tolerated (I found a few of those when I was testing). 
As a catch-all I probably need to do both of your suggestions in case the 
job is just stuck but not receiving any page requests. I'll give it a go 
when I get back from vacation next week.

Cheers
Michael

Michael,
Two things to try.
1) Are you setting on LR in those CGI apps or not? If not, then they might
be sitting waiting for something that will never get there, and eventually
they time out. You might want to try the SHTDN opcode; testing for an 
endjob
request. If that happens, set on the LR indicate to cause the program to 
end
when RETURN is issued. Of course that would only happen if someone hits 
the
page and the CGI program is called.
2) The other thing is to write a little tool that lists all the jobs for 
the
server. Then go through each one in a CL program and issue an ENDJOB
LOGLVL(0) and perhaps add the OPTION(*IMMED) if that's okay with you. To 
get
the list of jobs use the CrtJobList() API in the RPG xTools or call the
QUSLJOBI API and iterate through the list.
-Bob

Hi Brad,

Usually most of the jobs end within a couple of seconds, then two or three 

take 20 minutes to end and the final job is still running after 2 hours or 

more before I'm forced to cancel it. I'm fairly sure it's not a joblog 
problem as they're small like the okay jobs and I also don't see the jobs 
writing the joblogs when I do WRKACTJOB. Also, the final job sits on 
"TIMW"/"RUN" not "END".

Perhaps the slow and never ending jobs are struggling to complete a 
transaction of some sort, my colleague suggested (although he may have 
imagined it) that there may be a "flush" function in the Apache config 
that could detect problematic jobs and end them before they become a 
problem. If I can't find this then I guess I could write a procedure to 
abort any slow ending jobs a minute after the ENDTCPSVR command but this 
is a bit of a bodge which I hate. 

I'm off on holiday on Saturday so I've got to hand support off to a 
colleague (who doesn't have a baby!). It's a pain to leave this problem 
behind although it won't be the first thing on my mind when I'm relaxing 
on a Spanish beach!

btw in case you're interested Brad, the site in question is 
www.office-world.co.uk, it's actually a product that we sell called retail
therapy (see the URL below) all written native on the iSeries using 
CGIDEV2. Sadly one of the sales blockages we encounter a lot is that it's 
hosted on an iSeries, the combination of the unknown and the relative 
expense of the box has been a thorn in our side since the launch in 
February. We're even pondering whether to rewrite the product in .Net. 
However, Office World are a 400 shop so they know how good it is and 
they're very, very happy to have their website and (apart from this 
problem) it's just so stable and secure.

If you have any other thoughts I'd appreciate them Brad.

Cheers
Michael

Michael,

Is the job log quite large on this job?  That could be the
problem.  I hate that there's no way to end them quickly.
 Does it ever end on it's own?  (have you waited 10 minutes
or so?)

I've had similar problems where it seems to take forever to
end jobs  But they do eventually end.

Brad
