Since no one else has responded to this, I will take a shot.

If you do not have 5.0, then I would not install it with the GA of 5.1 only
about 3 weeks away.  NetView 5.1 contains all the
fixes to 5.0 that people have been asking for since it came out and
customers who have the early release are reporting that they are much
happier.  You will have to install a newer NetView than 4.1 within the next
year.  I just would not do it yet.

I would not plan on upgrading to NetView 5.1 as a performance improvement.
You will need more resources, not less, to run NetView V5.0 or NetView V5.1
than you did V4.1.  If you think you have a performance problem with 4.1,
then you should start investigating that now.

Sizing?  The best sizing information we have is in the current NetView
Installation and Configuration Manual.  There is base level (you already
meet those or you couldn't have 4.1 up) in the first chapter, and more
detailed stuff -- where you apply formulas for the number of users and the
size of your network -- in the Appendix.  How can you get this if you don't
have 5.0?  Try going to the Tivoli customer support web page,
http://www.support.Tivoli.com, and registering as a Tivoli customer.  Then
you can download the books online.  Can't do that?  Contact your local
IBM/Tivoli marketing office for help.

But please bear one thing in mind.  The NetView manuals will help you
figure out what you need to run NetView.  But they cannot help you with
Cisco products.  You will have to add considerably more to your estimates
for those.  And you will probably need new releases of those products to
work with NetView V5.0.  So now would be a good time to ask Cisco what
their memory and sizing recommendations are.

So what can you do now about your 4.1 system that doesn't seem to run as
fast as you like?
Let's talk about performance.  There are some basic things to check.
1. Paging space should be between 2-3X your real memory size.
2. Do ovobjprint -S and find out how many objects you have in your
database.  Make sure that the ovwdb cache size is a good 20% greater than
this value.  You can set that through SMIT under Configure  for NetView
daemons. It is the total number of objects in your database, not the number
of routers you have (how many interfaces are them -- 5, 10, 128 ?) that
determines performance.

Are those OK?  Then you have to do some real work gathering data to see
where the bottlenecks are and address them.  I suggest you get a hold of
SG24-4989-00 RS/6000 Performance Tools in Focus and start taking
You can also open a call the NetView Support and describe what you see as
the problems to them.  They will enlist the aide of our performance people
and attempt to help you.

I hope this helps
Good luck.

Subject:  5.0 vs 4.1

Hi to everyone !

I use NetView 4.1, CiscoWorks 3.0 and CiscoView 4.1 on PowerPC (model
43P-133, 128 MB RAM) based AiX 4.1 graphics work-station to monitor and
manage corporate network which consist about 80 Cisco routers.

It works, but ... I want it to work faster !

Can anybody tell me:
    Shoud I really upgrade NV 4.1 to 5.0 (I have never seen NV 5.0) ?
    How shoud I upgrade my equipment ?

If anybody has experience with sizing NetView 5.0 (or 4.1), PowerPC AIX
maschine and 80-100 routers network please help ?

What about NT and AiX combination ?

Pawel J.
