Re: MCH3402 received when calling getHtmlIfsMult

I may have found the problem - RCLACTGRP *ELIGIBLE. I have 2 examples now of the user running the program that uses CGIDEV2, one time she uses it 16 times, then MCH3402 - another program does RCLACTGRP, and CGIDEV2 AG is removed. Another time, over 35 uses, then MCH3402 - and again, RCLACTGRP precedes it.

Oy!! One solution is to RCLACTGRP individually, I suppose - and not do that to CGIDEV2. I know, probably not the ultimate answer, but maybe good enough.

So, again, thoughts are welcome - I'll be talking this over with another developer here, see what he thinks. But this fits. There was a support KB from IBM based on Jon and Susan's work, that described this when using RCLRSC, too.

Thanks all

Job log doesn't show anything - I'm wondering, how do we know what can't be found anymore? MCH3402 is not very informative.

In this case, the error comes back to the RPG program when calling the procedure - does it mean that the reference to the procedure is no longer known? Or is it something IN the procedure that can't find something?

Which brings us to ask - does CGIDEV2 somehow suppress or remove all joblog messages? If so, is there a way to see what happens internally? I do see a statement in one of the source members to change the job to LOG(4 0 *SECLVL) when ending things. Did not see the opposite when looking fairly quickly at the code. I think our jobs are using the latter logging level - another thing to verify, eh?

Thoughts are welcome, as always here!

Hi Brad

I have the job log, will post it here or where y'all can see it. I don't remember seeing anything, though. Opens and closes would be done by the functions of CGIDEV2. I do wonder about the template file itself, it has to be opened every time, but supposedly only if it has changed. Also, the user has responded to the messages with a C until there are no more, then can repeat the operation and is successful.

But I'll bring more info here.

Thanks
Vern

Can you post the job log? Maybe there's a clue there. It could be
something like too many open sockets/files. Especially if in your program
you are opening stream files and maybe not closing them all the time.

Y'all

We have one user who gets an MCH3402 a couple times a week when creating
receipts - the programs uses CGIDEV2 to create HTML files used to email.

It seems to happen after a busy morning of this. And it is to only 1 user.

Generally, the program does things in this order -

getHtmlIfsMult (only 1 template, though)
clrHtmlBuffer
updHtmlVar/wrtSection as needed
wrtHtmlToStmf

There is no information in CGIDEBUG that helps.

MCH3402 generally means that something a pointer points to is gone,
right? But it has to be in the getHtmlIfsMult.

I don't think we are running out of memory, and that isn't the cause for
MCH3402, is it, anyhow?

Our solution right now is to wrap a monitor/endmon around the call to
getHtmlIfsMult, display something to the user, then back to the caller.
They are able to go to a different app and resend the receipts.

OK, enough, TIA
Vern
