properties, recognition statistics, etc., if a script for successfully published jobs is specified. If a script for failed jobs is
entered, images that failed to be processed are delivered to the destination specified in the script.
Centralized Administration
ABBYY Recognition Server 3.5 is administrated via a separate component, the Remote Administration Console, which is
based on the Microsoft Management Console (MMC). The Remote Administration Console allows administrators to
change Recognition Server's properties, connect Processing Stations and manage their properties and activity, create and
manage workflows, add users to the system and assign Administrator, Verifier, and Indexer permissions to the users,
monitor connected Verification and Indexing Stations and the job queue, view and export the job log and the server log,
and manage licenses.
If several ABBYY Recognition Servers are installed in the local area network, they can all be registered in the same
Remote Administration Console and thus all managed from a single point. See Registering a New Recognition
Server.
Scalability
One Server Manager can manage dozens of Processing Stations connected to it and effectively distribute the workload
among them. This makes the whole system highly scalable to meet high-volume processing demands. By connecting
multiple Processing Stations, you can increase the processing speed up to several hundred pages per minute.
Note: The picture shows the speed increase as measured in ABBYY's internal tests. System performance may vary
depending on the complexity and quality of the images, the hardware of the server and the stations, and the network
configuration.
Fault Tolerance
As ABBYY Recognition Server 3.5 runs completely unattended, it has a number of fault tolerance features that ensure
robustness of the system:
The system starts automatically at Windows startup. For example, in the case of a temporary power outage,
ABBYY Recognition Server will be up and running automatically after the PC is rebooted.
Documents are processed so that no data are lost in the case of a system failure. All the images that were being
processed when the failure occurred will stay in the queue and will be processed again after the system is
restarted.
The Server Manager periodically checks to make sure that the Processing Stations are running and are available.
If a Processing Station is temporarily down for some reason, the Server Manager will re-establish connection
with it after it becomes operational. No administrator's involvement is required to re-connect a Processing
Station.
If a Processing, Verification, or Indexing Station experiences a failure while processing a document, the
document will be automatically re-routed to another available station. If no station is available at the moment,
the image will remain in the queue and wait for the first available station.
