Re: Job Log Wrapping - caused by Live Outline?

The annoyance is that it's sending a message to qsysopr. So there's that annoyance, plus my manager is concerned about the excessive unnecessary logging. Ultimately, the problem is that we can no longer see a job log message wrapping message on qsysopr and say "something might be wrong" because anything that may be wrong is going to be hidden amongst the hundred other job log wrap messages - and should our person now investigate all of these messages every day?

One example of an issue we found through a message queue wrapping issue: A cross-system function was checking a data area before every write to a file to make sure the file wasn't in use by another process. This was causing job log wrapping when the user was loading millions of records (thus millions of data area checks). Our fix was to have it check the data area once, then flag it as being in use by this import function, and then at the end reset it.

Now that I think about it, I don't think I'll get it both ways. Unless there's a way to modify only the job description for the automatic RDP jobs, which I have no idea how to isolate to just RDP (QZBSJOBD is "Host Server Job Description"), to do away with this message wrapping by the outline refresh will also do away with another jobs' information as well (for instance excessive repetition of one function, such as checking a data area).

Not meaning to sound sarcastic, but who is it annoying and why? I thought (could be wrong here) that *Wrap generally just overlaid the oldest messages and kept on truckin'.

If not, what is occurring and whom is it affecting when the MSGQ wraps?

Jack - Yeah I'm in that unfortunate position where the wrapping is annoying someone, and I'm being asked to look into it. ;)

Gary - same result as what I tried earlier. Job log appears empty, but still get the message queue wrap message.

Either that or if you have support maybe you can open a call to IBM. Are you current on service packs and ptf's on both sides. The wrapping me just be more informational than problem-matic.

Ok, I see what you mean.

Here are the options:
*SAME
*SYSVAL
*NOWRAP
*WRAP
*PRTWRAP

So right now it's *WRAP. If I change it to *NOWRAP the job will end. I
could change it to *PRTWRAP... but that would mean a lot of reports
will generate simply because of the live outline running.

What I think needs to stop happening is for the job message queue to
not record every action that the live outline is performing. Is there
a way I can control that? As mentioned earlier, this didn't seem to
do
it:
CHGJOB JOB(802186/QUSER/QZRCSRVS) LOG(0 00 *NOLIST)

Maybe I should take this to the Midrange-L list, but I posted here so
those at IBM would be aware of this side-effect of the outline refresh.

I was thinking if you change this JOBMSGQFL for the job.
I don't have RDP currently.

Override it to do what? To not wrap? To not give a message when it
wraps? Even so - is there a way to modify the RDP jobs only?

On the CHGJOB there is a keyword to override the wrap as well.

I gave it a try, but no luck.

CHGJOB JOB(802186/QUSER/QZRCSRVS) LOG(0 00 *NOLIST)

And verified that the job logging level was at 0.
Still had message wraps after opening a number of RPG source to
trigger the outline update. However, the job log itself was empty.

can you track your job down once it is active, if so change the
level to 0 and the queue max size just to see what happens, this
way your not touching the global system values. If it fixes it
then your all set at least while your connected, might be worth
the
test.

The job description is QZBSJOBD

Here is some info from the jobd, although I'm not sure if it helps:
Message logging:
Level . . . . . . . . . . . . . . . . . . . . : 4
Severity . . . . . . . . . . . . . . . . . . . : 0
Text . . . . . . . . . . . . . . . . . . . . . : *NOLIST
Log CL program commands . . . . . . . . . . . . : *NO
Job message queue maximum size . . . . . . . . . : 4
Job message queue full action . . . . . . . . . : *WRAP

I suppose we could increase the message queue maximum size...
although I tend to be a bit hesitant about changing system
values mainly b/c I don't have a few view of what all this will
affect.

Wonder what is in the messages causing it to do this.\ Maybe you
can track down the jobd that this is using and change it.

Lately our shop has been very sensitive about various job logs
wrapping.

I'm being told that I'm causing some job log wrapping to occur.
I did a little testing, and it appears to be related to when I
open a RPGLE source and the live outline kicks off. The job
log in question is
filled with:
Client request - run program QSYS/QWCRTVCA.
Client request - run program QSYS/QVDEOBJL.
And every so often:
Ownership of object IDEnnnn in QTEMP type *USRSPC changed.

I think the wrap occurs after I open 3-4 RPG sources with
about 2k lines of code (that use a number of service programs).

Not to say this hadn't happened before. Maybe it did,
although possibly less often when it wasn't refreshing the
outline on every
source open.

Is there anything that can be done about this? Or is this
simply something that operations needs to live with?
