Processing Server

The Processing Server distributes the workload among the Processing Stations. Together with the Processing Server, a Processing Server Monitor is installed, which is used for monitoring the server. Document processing proper is done on the Processing Station.

Once the Processing Server is installed, you should configure it: start the server, add, set up and start the Processing Stations.

Note: Before starting the Processing Server, make sure that the Processing Server access permissions have been granted to the account under which the server is running ($).

A description of the setup process is provided below.

Starting the Processing Server

Starting the Processing Stations

To set up the Processing Stations:

In the server tree, select Stations and click . The Add Stations dialog box appears. Select the desired stations from the overall list. You can also specify the name of the computer or its IP address. You can specify the name of the computer even if dynamic IP addresses are used. Use IP addresses if you experience problems accessing the DNS network.
Select Actions → Properties and in the Station Properties dialog box, specify the parameters of the station:

Name - the displayed name of the station;
Group - the group to which the station belongs.
Start automatically - this flag means that the station is started automatically by the Processing Server; by default this option is selected;
Note: Frequent attempts to start too many stations may considerably slow down the Processing Server
Required disk space - the minimum disk space required for the operation of the Processing Stations; if there is not enough free disk space, the station will be stopped. The space specified in the field should be three times as large as the maximum size of an image that can be in processing. The optimal value of the minimum disk space is the doubled maximum size of a batch that can be in processing;
Maximum number of processes - the maximum number of CPU cores that can be used for task processing;
Allowed number of processes - the allowed number of CPU cores for task processing; this parameter is computed automatically based on your hardware and license parameters and cannot be changed;
Process priority - the priority of the process;
Acceptable task types - the task types that the station can handle:

Import images - import tasks;
Recognize pages - recognition and export preprocessing tasks;
Verification support - merging results of double verification as well as pre- and postprocessing tasks for the Web Verification Station;
Custom processing - processing batch and document processing scripts;
Export documents - document export tasks.

Click to start the station manually or wait for the station to start automatically (if the Start automatically option is selected, the station starts automatically within a minute).
Note: The Processing Station can be stopped by using hard or "soft" stop. If you need to stop the Processing Station, for example, for upgrade purposes, you can use the "soft" stop. For this, select Actions → Stop. In this case, all current tasks are completed and afterward the Processing Station is stopped. New tasks are not taken into processing.
To do a hard stop of the Processing Station, select Actions → Stop Immediately. In this case all current tasks will fail.

The stations receive the permissions to process documents from the Processing Server when they connect to the server.
