Thanks James,
I had an opportunity to install 6.0.2 this weekend. But I haven't tried my
script yet. However, the cron job that runs similar commands works at the
time scheduled (11AM CST). It only runs 1 cycle of node down/node up. I
think I was possibly cycling the test too fast. The ruleset reset on match
node was set for 1 minute. So a page would occur for each cycle of the
script. Here's the script:
##################################
#echo "Start of script"
/usr/OV/bin/nv6000_smit run_event -n'1' -e'AA_EV' -h'tnvcorp02' -s'N' \
-d'1. Ruleset testing is about to begin.' >/dev/null 2>&1
sleep 1
##################################
/usr/OV/bin/nv6000_smit run_event -n'1' -e'AA_EV' -h'tnvcorp02' -s'N' \
-d'SIMULATE 9816 DOWN FOR MORE THAN 1 MINUTE(S). PAGE SHOULD
OCCUR.'\>/dev/null 2>&1
/usr/OV/bin/nv6000_smit run_event -n'1' -e'NDWN_EV' -h'blah.blah.com'-s'N' \
-d'This is a test.' >/dev/null 2&>1
sleep 70
/usr/OV/bin/nv6000_smit run_event -n'1' -e'NUP_EV' -h'blah.blah.com' -s'N' \
-d'This is a test.' >/dev/null 2&>1
/usr/OV/bin/nv6000_smit run_event -n'1' -e'AA_EV' -h'tnvcorp02' -s'N' \
-d'TEST CYCLE COMPLETED.' >/dev/null 2>&1
##################################
Do you think my test was too hard on the patient, Doc?
Ray.

I've given this some more thought, and while my advice to call Support is
still the same, especially if nvcorrd fails when you ovstop actionsvr. But
what you want to do with the issue of your pages not occurring is to try to
determine where this is failing. If you cannot find error message then you
will need to set up some tracing and try a "divide-and-conquer" approach.
First trace nvcorrd activity with nvcdebug -d all" and look at the
nvcorrd.alog/blog. You will see each trap as it is processed. Look for
"Receive a trap" and "Finished with a trap". Everything in between is
nvcorrd processing that trap. You should see the action, whether paging
via the paging node or a script of your own being kicked off as an action
sent to the actionsvr. If that looks OK, then look in the
nvaction.alog/blog and see what happens when that action gets there. You
should see a line where it is launched and then any error messages that
come back. No error messages? Then I would start tracing the pager
daemon. You can do that by adding -d to his ovsuf entry as has been
explained in this list many times. He will start writing voluminous output
to nvpagerd.alog so you can watch every page being sent. You will
probably need help somewhere along the line, so I'd recommend that call to
Support.

You need to call Support and open a problem. The help you need is much too
detailed to be given on the forum like this. Someone needs to examine your
ruleset and set up some tracing, and if you are getting a core, then we
need a core report and that will have to be analyzed as well.

James,
I've been testing these rulesets all day. I get about an 80% success rate
on
paging. When the breaks occur nothing happens on the nvcorrd log or
nvaction
log. I know that nothing is received at the paging server also. The next
time I run my script it may work. A restart of daemons is not necessary.
I hope to install 6.0.2 Monday evening. I know there is a fix for an
nvcorrd
core dump problem. I encounter the problem every time I stop actionsvr. Is
there an nvcorrd problem in 6.0.1 that could cause this symptom?
Thanks.

Ray -
netstat -a will show you what I was talking about, which aren't really
queues but messages on the sockets of various UNIX processes. If
everything is working right, you should see the send and receive queues be
at zero or near zero, indicating that the processes involved are getting to
every new message right away.
Since netstat uses the /etc/services file to identify the port owners, you
should see some part of the word "nvcorrd" as part of the named process
owner. If your hostname is too long and you don't get enough displayed,
you can try "netstat -an" which gives a numeric display. nvcorrd's port is
1666. Sockets are assigned in pairs, for interprocess communication, so
you when you have rulesets running you will always see another process
shown who's information is the obverse of nvcorrd's -- the receive and send
amounts will be swapped.
Assuming you are doing paging in the standard fashion, either from an
action node in the a ruleset which calls your own script, or from the pager
icon, both result in the actionsvr actually doing the page. He logs
everything so go check out /usr/OV/log/nvaction.alog and .blog for clues.

Subject: [NV-L] nvcorrd queue
Hello James,
Back in '99 you wrote a nice Ruleset Performance document. In it you talk
about the nvcorrd daemon and the queue (32K) filling up. I'm having a
problem with an intermittent paging ruleset. I was wondering what do look
for in the nvcorrd.?log file to indicate a queue problem.
Thanks in advance.
