[OES2 SP1]

I just created some address records with iManager 2.7.3 and I querying
these names did not give any result until ... I restartet rcnovell-
named...! Could that possibly be true?

The documentation says:
"1.2.5 Dynamic Reconfiguration
A Novell DNS server supports dynamic reconfiguration. The DNS server
automatically detects and updates any change in the server's or zone's
configuration data. This enables the server to configure itself with
these changes without having the administrator intervene to stop and
restart the server. Also, out-of-band data changes (creating, modifying,
deleting RRs through management utility) are addressed."
