10.6.3 Configuring Replication Partners
WINS servers communicate among themselves to fully replicate their databases, ensuring
that a name registered with one WINS server is eventually replicated to all other WINS
servers within the network. All mapping changes converge within the
replication period for
the entire WINS system, which is the maximum time for propagating changes to all WINS
servers. All released names are propagated to all WINS servers after they become extinct,
based on the interval specified in WINS Manager.
Use the Replication Partners command in WINS Manager to configure replication
partners and replication partner properties.
Choosing whether to configure another WINS server as a push partner or pull partner
depends on several considerations, including the specific configuration of servers at your
site, whether the partner is across a wide area network (WAN), and how important it is to
propagate the changes.
Replication is triggered when a WINS server polls another server to get replicated infor-
mation. This can begin when the WINS server is started, and is repeated based on the
configured update count or time interval, or by using WINS Manager to start immediate
replication.
Replication also is triggered when a WINS server reaches a threshold set by the adminis-
trator. This is an
update count for registrations and changes. In this case, the server notifies
its pull partners that it has reached this threshold, and the other servers then can decide to
pull replicated information.
It is always a good idea for replication partners to be both push and pull partners of each
other. The primary and backup WINS servers
must be both push and pull partners with each
other to ensure that the primary and backup databases are consistent.
Configuration option Description
Database Backup Path Specifies the directory where the WINS database backups will be
stored. If you specify a backup path, WINS automatically
performs a full backup of its database to this directory. WINS also
uses this directory to perform an automatic restoration of the
database in the event that the database is found to be corrupted
when WINS is started. Do not specify a network directory.
