I would like to throw in my 2 cents if I may. I still consider myself a novice
at supporting
Netview but this is what I did to check this out.
I had my r/w map open on my X-station at my desk. I opened an r/o map on the
X-station in our
command center. On the r/w map I managed an interface on and AIX server I knew
would turn red.
I checked the r/o map every couple of minutes for about 15 minutes. No status
change appeared
until I did a refresh on the map. Then the interface I had managed showed up
red. No HSRP involved
here.
Next I unmanaged the same interface. Brought up an IP map through the web
interface. Re-managed
the same interface. Within a second of the r/w map showing red the same
interface on the web
session showed up red.
Until this came up on this forum I thought it was just the way the r/o map
worked. So I created
another r/w map for the Command Center here, so their map would dynamically
update.
James, are you saying that I should open an PMR on this situation ?

I just posted a re-create scenario. Does it work for you or not?

I don't know if its related to our environment or what, but we noticed that when
we upgraded from NV AIX 5.1.1 to 5.1.2, status updates did not occur in a
reliable fashion on the R/O maps if there was no R/W map open. Network
Operations will notice a difference (and call) in about 20 minutes if the map is
not open. There must be some correlation there. It definately started with
5.1.2

Subject: Re: NetView over XWindows?
There are two issues here, not one.
(1) How does NetView work over a normal X GUI, and
(2) How does NetView work over a particular emulated X GUI.
I can answer the first. I don't know about the second. We do not use emulators
on a regular basis, though some individuals do, and we do not test the product
with them. Our job is done when the X GUI works. It is up the particular brand
of X emulator to reflect that on the emulated display.
Do you need a read-write map open to see status updates on a read-only map?
The answer is "no".
For an already-discovered object, present on the map at the time it opened, the
icons will change color as status is updated. I just tried it with the 5.1.2
boxes on my desk. I opened the only map read-only (netview -ro), did a locate
and opened the segment submap and the collections submap (the collection was on
SNMP-supported objects), and saw my other box (this one I am using to send notes
with). It was green and normal. I simply shut it down and watched the other
box, the one with the open read-only map, and waited for the events to come into
the event display which indicated it was down. The icon on both submaps I had
opened turned red as expected when the events were in the display. I then
powered up the down box and shortly thereafter netmon noticed it, and once again
I got the Up events and the icons turned green at about the same time. This
proves conclusively that status will propagate correctly to a read-only map when
there is no read-write one opened.
Now, if this isn't what you see on your X GUI then you have a problem that you
should notify NetView Support about. Note that I am not talking about devices
discovered after your read-only map is opened, or about devices coming and going
into collection submaps based on status. A read-only map will not re-position
an icon without a refresh, but if we are talking about just the color of an
existing object, this should propagate fine.
Hope this helps

Subject: Re: NetView over XWindows?
About this business of needing a r/w map open for r/o maps to work:
I have heard this rumor here before, but I have trouble believing that it
is working as designed. Has anyone taken it up with support and been
officially notified that a stand-alone R/O map will not reflect status
correctly? I am just about positive that this has not always been the case,
and I don't see it documented as a feature....
If I were not getting status updates, I would suspect that the ipmap
process
for that user had failed, possibly due to insufficient ulimits.
I would appreciate word from anyone who has been given this information
by Support, as opposed to just observing what works and living with it.
(Now watch me get in trouble with Support for asking questions like
this....)
Cordially,

Mark,
If you do not have read/write access to the map it will not update unless
you do a map refresh.

Subject: NetView over XWindows?
I am attempting to have a NT client off a NetView for UNIX using Exceed.
I am sending the DISPLAY back to my NT desktop from the NetView for UNIX
server
, it displays OK and the Menus work, BUT, the maps or submaps do not update
with status changes. For example: Nodes is a critical state.
A FILE-REFRESH MAP updates the screen.
A NetView session is already running when netview is executed from the
command line.
Has anyone attempted this or is this a known problem?
