The Processing Server distributes the workload among the Processing Stations. Together with the Processing Server, a Processing Server Monitor is installed for monitoring the server. Document processing itself is done on the Processing Station. Once the Processing Server is installed, configure it: start the server, and then add, set up, and start the Processing Stations.
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.

The setup process is described below.

​
Start the Processing Server

1

Launch the Processing Server Monitor

Launch the Processing Server Monitor by selecting Start → All Programs → ABBYY FlexiCapture 12 Servers → Processing Server.
2

Add the server

On the server tree, select ABBYY FlexiCapture Servers, right-click, and select Add Server….
3

Specify the server location

In the Add Processing Server dialog box, specify the server location (Network host or Local host).
4

Provide the Application Server path

Select Actions → Properties and provide the path to the Application Server (https://<ApplicationServer>, where <ApplicationServer> is the name of the computer on which the Application Server is installed). If the Processing Server and the Application Server are installed on the same computer, specify its name directly — using the IP address 127.0.0.1 or localhost will render the Processing Stations inoperable.
On the Application Server, start the Administration and Monitoring Console and assign the corresponding role to the computer on which the Processing Server is installed.
5

Start the server

Click to start the Processing Server.
The Processing Server can be stopped with a hard or “soft” stop. To stop it — for example, to upgrade or to move a database — use the “soft” stop: select Actions → Stop. All current tasks are completed and the Processing Server is then stopped; no new tasks are taken into processing. For a hard stop, select Actions → Stop Immediately; all current tasks fail.

​
Set up the Processing Stations

1

Add stations

In the server tree, select Stations and click . The Add Stations dialog box appears. Select the 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.
2

Configure the station parameters

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 — the station is started automatically by the Processing Server. Selected by default. Frequent attempts to start too many stations may considerably slow down the Processing Server.
  • Required disk space — the minimum disk space required for the Processing Stations to operate. If there is not enough free disk space, the station is stopped. The space specified in the field should be three times the maximum size of an image that can be in processing. The optimal value is twice the 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 value 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 the results of double verification, and pre- and post-processing tasks for the Web Verification Station.
    • Custom processing — processing batch and document processing scripts.
    • Export documents — document export tasks.
3

Start the station

Click to start the station manually, or wait for it to start automatically (if the Start automatically option is selected, the station starts within a minute).
The Processing Station can be stopped with a hard or “soft” stop. To stop it — for example, to upgrade — use the “soft” stop: select Actions → Stop. All current tasks are completed and the Processing Station is then stopped; no new tasks are taken into processing. For a hard stop, select Actions → Stop Immediately; all current tasks fail.
The stations receive the permissions to process documents from the Processing Server when they connect to the server.

​
Create station groups

You can isolate different tenants from one another at the task level. To do so, create the required Processing Station groups and then assign a group to each new tenant you create. To create a station group:
  1. In the server tree, select Station groups and click . The New Station Group dialog box opens.
  2. Specify a group name and select the stations from the overall list.
  3. Click OK.
The group appears in the list, and you can then specify it for tenants in the Administration and Monitoring Console. For more information, see Managing tenants. To change the name of a group or its list of stations, select the group in the list and click Edit Station Group… in the context menu. You can also add a station to a group by selecting the group in the Station Properties dialog box.

​
Set up the Processing Server log

1

Open the log settings

Open the Processing Server Monitor settings by selecting File → Settings….
2

Choose which messages to log

Specify which messages should be logged (Errors, Warnings, Information messages).
3

Choose whether to remove completed tasks

Specify whether information about completed tasks should be deleted (Remove completed tasks from the list).
4

Choose which messages trigger logging

Specify which messages trigger logging of information about the task.
Do not disable the Remove completed tasks from the list option during normal operation of the system, as this may cause a pile-up of data and slow down the Processing Server Monitor. Disable this option only when setting up and tuning the system.
5

View the task log

Click to view the task log. To save a task log as a .txt file, click the Export Log… button in the dialog box that opens.

​
View task information

To view task details, select Tasks in the Processing Server tree. For each task, the following parameters are displayed: task name, start-up time, progress, status, priority, and the station name. Failed tasks are marked with . If, besides an error message, the task log also contains informational messages, the task is marked with .

​
Service log

Besides the regular task processing log, the Processing Server and the Processing Station can keep a service log. ABBYY technical support staff may need information from this log when handling your support requests. Service logging does not slow down your Processing Server or Processing Station, but the information it contains is only useful to ABBYY’s technical support engineers, so we do not recommend keeping service logging permanently enabled. If a technical support engineer asks you for a service log, follow these steps:
1

Open the properties dialog box

Depending on which log is required, open the Processing Server Properties dialog box (select Properties on the shortcut menu of the Processing Server) or the Station Properties dialog box (select Properties on the shortcut menu of the Processing Station).
2

Enable logging

Select the Write processing log option and click OK.
3

Collect the log files

Once the log files are created, find them in %programdata%\ABBYY\FlexiCapture\12.0\FlexiBrSvc\Logs. Send copies of these files to ABBYY technical support.
4

Disable logging

Disable service logging by clearing the Write processing log option and clicking OK.

​
Manage the Processing Server from the command line

The Processing Server can be operated from the command line:
  1. In the Windows Start → Run menu, type cmd and click OK. A command-line prompt window appears.
  2. Type the path to the FlexiBRSvc.exe file (by default, C:\Program Files\ABBYY FlexiCapture 12 Servers).
  3. Enter commands in the form FlexiBrSvc Please [command]. To enable command mode (so that you do not type FlexiBrSvc Please before each command), use FlexiBrSvc Please obey; to disable it, use FlexiBrSvc Please quit. The commands let you start or stop a station, display the station list, start or stop the Processing Server, add or remove stations, view information about a station, and set server and station parameters.
  4. To show the list of allowed commands and other help information, type FlexiBRSvc.exe /?.
For a detailed description of all commands, see Description of Processing Server commands.
