What a head-scratcher! I'd been working on refining the discovery of a Customer's network, when one day all ITNM Network Views started appearing as if they were empty! What was particularly strange is that this change came on suddenly, during a period where I had made no changes to the Customer ITNM deployment. The only thing that had "changed", so to speak, was that my laptop had been forcibly rebooted by our Tivoli Endpoint Management software. I don't know if it was an update to the IBM java client itself, or something related to it, but the same Network Views that worked the day before now showed up empty.
The first thing I did was check the NCIM database, to make sure the entities were still there. I could still report on the entities via SQL, so it had to be something with Topoviz or the actual Java client.
One nice thing about Topoviz is that if you change the logging level in the properties file, you don't have to restart anything. I edited the
$NCHOME/precision/profiles/TIPProfile/etc/tnm/topoviz.properties file, and changed this property: topoviz.log.level=ALL

Right away, the $NCHOME/precision/profiles/TIPProfile/logs/tnm/ncp_topoviz.0.log file started to have much more information about what the client was doing. But it still didn't make sense to me.
It was time for help from Support, and I was pointed to this Technote:
