Program Initialization

The program reads out of the database all input commands not in a final state (processed, timed out, cancelled) and all the owned operations and output commands and starts progressing these commands. Only unfinished commands will be read. All others will be ignored and not validated for errors.

If there are any errors found in reading the database, the daemon will not start. It will then be necessary to provide a (probably) empty database so that the daemon will start from fresh and not progress any previously running commands.
