Scale OCR
A typical deployment features only one OCR instance. You can add more instances and combine them into a single cluster without the additional configuration of Control Tower.
note
The guide assumes that the user is already familiar with the WorkFusion installation procedure.
Set up primary server
Install the primary server as described in the installation guide. Concurrent executions are based on available CPUs or can be configured.
Set up secondary server
The main idea is to add the OCR Worker component by installing the full OCR component pointing to the existing INT server.
Check prerequisites
- The INT Server is installed.
- The primary OCR Server is installed.
Install and configure
- See Linux or Windows server installation procedures according to the selected OCR platform.
- Check that the Workers point to the same MSSQL instance.
- Ensure that
ocr.health.worker.nameis unique. - See Perform OCR health check for details.
Validate
- Check that the Worker process is started without errors. Refer to
ocr-worker.log. - Load documents to the OCR Server: the
ocr-taskprocess must start, andocr-task.logis created on the primary and secondary servers.
