RE: [nv-l] nvUtil and nvcold

["Bursik, Scott {PBSG}" <Scott.Bursik@pbsg.com>]

I increased the size of the ovwdb cache to 150,000 and did a ovtopofix
-A while I had the daemons down and my performance is back to normal. I
did see that I had 5,000 less objects in the database after the
ovtopofix though. Very interesting.

Thanks for your assistance James.

Here is what I have found:

ovobjprint | head -1
Number of objects defined in the database: 129432

root  52936  69904  73 13:42:37      - 963:18 /usr/OV/bin/ovwdb -O
-n130000 -t

Very close! Looks like I should raise the cache size. How much higher
would you suggest? Our network recently went through some growth so this
explains what I am seeing. Would these number being so close cause the
slowness I am seeing now?

Thanks!

Scott

Thanks for the tips James. Yesterday nvUtil commands weren't coming back
at all and after the daemon refresh it is just returning slowly. I will
make some checks and see what I can find.

I think you mean
NetView 7.1.4 AIX 5.2


There's a big difference between "never comes back" and "takes a long
time
to return".  The latter indicates a performance problem, and to solve
that
you need to look at what else is going on in the system at the time and
what other things use smartsets.  Got rulesets accessing smartsets too?
How about xnmsnmpconf?  snmpCollect?

One other thing to remember.  nvcold gets his information from ovwdb.
Smartsets, after all, are just objects in the database with various
attributes set.  So anything that slows down ovwdb could slow down
nvcold.
Does ovobjprint work OK when this happens?  Is you ovwdb cache size
larger
than the number of objects ovobjprint -S shows you?  You wouldn't
necessarily have to add a new smartset to cause things to slow down.  It
might be sufficient to add many new members to exisiting ones or
significantly add new objects to the database.

I am having an issue where nvcold quits responding. It still shows as
running but when I try and run nvUtil commands it either never comes
back
or takes a long time to return. I recycled all of the daemons 2 times
yesterday and the issue keeps coming back. I haven't added any new
Smartsets. Any suggestions?

Thanks!
