RE: [NV-L] Some systems dont get added to the submap.

[Leslie Clark <lclark@us.ibm.com>]

Rajesh, no one wants to discourage you
from taking advantage of the programming interface, but I for one would
just like to be sure you know about the alternatives that have led to those
APIs being less used than they used to be. My apologies if you know all
this already. 

If you are only trying to represent
those hosts from different subnets in a common submap, then a Smartset
based on the field "EServer_sysName ~ ." (it exists), will give
you that. The Smartset editor is under Tools. Things in the Smartsets remain
managed by netmon and ipmap. 

If however you intend to also write
a management application that is going to manipulate their status, then
you may have a reason to go to the trouble of developing a topology using
the APIs. 

Cordially,

Rajesh,

It looks like you the condition (pObjectIdList->count > 0) is returning
false for some of the systems because there are no matches for the
conditions you are searching for (field EServer_sysName = workstationname
?). This may be due to a hidden character in the field data (space),
character case, etc. so I would double check the field values in the DB.

Based on the documentation for OVwDBListObjectsByFieldValue, if no match
was found that the OVwObjectIdList will contain no object IDs and still
be
considered successful.

I'm not sure if this could help you, but maybe you could achieve what you
need by using the location.conf file or a smartset.

Jane,
Sorry I did not mention anything in the subject line of the mail
earlier.
The earlier mail which I sent in html format failed to reach nv-list
because it was 60 KB and I had to switch to plain text format.

In the scenario I am using there will be certain systems with our SNMP
MIB running on them. We need display them on the console using our own
submap representation. The submap is created perfectly but some of its
components fail to add.

The problem is that
1. Some systems are not getting added to the submap. They fail to add
when pObjectIdList->count > 0 is false.
2.I want to know why the condition (pObjectIdList->count > 0) is
becoming false for some systems (ie pObjectIdList->count is 0 instead
of
being 1).


Thanks,
Rajesh

Hi Rajesh,
Perhaps you might explain a bit at a higher level, what you are trying
to achieve?  Most people who use NetView do not need to resort to
programming with the APIs.  Perhaps there is an easier way of achieving
what you want??
Cheers,
Jane
