Table 4–1: NameServer properties (5 of 6)
Property category or property Description
Neighboring NameServers A list of selected NameServers to which this
NameServer can forward connection requests
for application services that are not registered
with it (that is, the application service name is
unknown). The list contains all NameServer
instances defined in the management console,
initially with none selected. To make a
NameServer a neighboring NameServer,
select the unselected NameServer to highlight
it. You can select as many NameServer
instances as you want to be neighboring
NameServers. Each neighboring NameServer
thus appears highlighted in the list. To remove
a NameServer from the list of neighboring
NameServers, select the already-selected
NameServer to remove the highlight.
The setting of this property is optional. When
a NameServer receives a request for an
application service name that is unknown and
there are no neighboring NameServers
specified, the NameServer sends a message to
the requesting client indicating that the
application service is unknown. When such a
NameServer has neighboring NameServers
specified, it forwards the request to each of the
neighboring NameServers. The first
neighboring NameServer that has the
application service name, and responds to the
connection request, provides the specified
connection to the client.
TCP/IP Version Internet Protocol for network communication:
• IPv4 — Accepts only IPv4 connections
• IPv6 — Allows IPv4 and IPv6
connections using mapped address
(where supported)
The default is IPv4.
You must also set the jvmArgs property in the
ubroker.properties file to override the
default behavior of the JVM for IPv6
connections.
Enable dynamic property
updates
jvmArgs=-Djava.net.preferIPv4Stack=fal
se -Djava.net.preferIPv6Addresses=true
Allows dynamic changes to occur to several of
the instance’s properties, without requiring
you to shut down the instance.
This property is disabled by default.
Note: Any property that is dynamic is labeled
as such in this document.
