Introduction
The Process Manager can be configured via environment variables. See the table below for available options. Values representing time intervals can be in seconds (s), minutes (m), hours (h) and days (d).

Notes
Process is a task or activity that the system performs. For example, performing an OCR operation on an image. The Process Manager accepts processes from a caller, delegates them to a worker (e.g. OCR Reader Worker) and reports the final state to a caller. The process life time is limited by PROCESS_LIFETIME_MIN and PROCESS_LIFETIME_MAX values. The Process Manager stores the worker's activity (Activity Data) for the process in the database. After the ACTIVITY_DATA_LIFETIME period has been reached, that data will be cleaned. If the process has exceeded the maximum number of processing attempts (PROCESS_ATTEMPTS_MAX), it is considered as failed.
