Replication and Synchronization Server
Virtuoso Replication Services are a tool
for distributing consistent and timely data within
distributed information systems, , avoiding dependence on
centralized hubs and single points of failure. Safety,
consistency, and flexibility are all reasons for using
Virtuoso's replication services.
Virtuoso replicates and synchronizes data
between servers using a variety of replication modes,
including:
-
Bi-directional table replication.
Virtuoso as a hub, supervising replication events between
groups of MS SQL Server, Oracle or DB2 databases.
Virtuoso will initiate data transfer and resolve possible
update conflicts.
-
Disseminating periodically changing
data between heterogeneous relational databases. Almost
any ODBC/JDBC accessible database can be a source or
recipient of such data.
-
Keeping Virtuoso WebDAV repositories
in sync between Virtuoso installations.
-
Keeping Virtuoso servers in real-time
sync for load balancing or hot standby situations. This
is based on real-time log shipping, thus will also work
for intermittently connected systems.
-
Sharing mobile data through SyncML.
The Virtuoso SyncML server has pluggable logic for format
conversions between common mobile formats such as Vcard
and Vcalendar.
These replication modes function reliably
with a constant or periodic connection to the network. Nodes
will automatically synchronize upon reconnection.
A web based interface or Virtuoso/PL
statements are used for defining publications, subscriptions,
and synchronization intervals.
