In-Depth Information
Here is a description of the command-line options:
State : Optional parameter that specifies whether you want to use persistent connections
for replication. A value of 0 indicates not to use persistent connections; a value of 1 indicates
to use them. The default connection type is persistent.
Server : Required parameter that specifies the IP address or the NetBIOS name of the
pull-replication partner.
Update : Required parameter that specifies the number of changes in the version ID (the
number of record updates) that must occur before replication starts.
For example, use this command to configure the push-replication parameters for the
current server with the WINSB server. WINSB will be notified after three changes in the
version ID:
> netsh wins server set pushpartnerconfig state=1 server=WINSB update=3
How It Works
You can configure replication parameters for a given partner in a single screen of the WINS
Administrator console; however, two distinct commands are required to set these options
through the command-line interface.
The version ID that has been referenced in this recipe can loosely be interpreted as the
number of entries in the WINS database. More to the point, and as quoted in the Microsoft
TechNet site, “the value in the version ID reflects the total number of replicable changes that
occurred to owned entries for a particular WINS server. The value is incremented by hexadecimal
1 every time a replicable change occurs. For example, if WINSA is the owner for ClientA, which
has a version ID of 4B3, and for ClientB, which has a version ID of 4C2, ClientB was the fifteenth
replicated change in the WINSA database after the ClientA change.”
Replication parameters must be configured on a per-replication-server basis; these are
not global in nature. You should apply careful thought to the configuration of these replication
parameters. For multisite environments, it is helpful to create a visual diagram that includes
schematic representations of each site, as well as the intersite links. You should determine
whether a hub-and-spokes replication topology is the most appropriate or whether you need a
complete mesh. See “Configuring WINS Replication” in the WINS help file for a summary of
replication and topology considerations.
The goal of the configuration of WINS replication is to minimize the convergence time and
the impact on network performance. The convergence time is defined as the amount of time it
takes for a change that occurs on one WINS server to propagate to all other WINS servers in the
replication environment.
