In the sample below there are two different approaches described how you can start jobs on a file event.

Using a file order source

See also Documentation

the The job chain "job_chain_file_order_source" has a file order source looking watching for files in c:\temp\input ending with the file name extension ".txt". When a file arrives, an order for the job chain will be created. The file will be erased at the end of the job chain by the file sinkssink node(s).

• Orders can not have additional parameters
• Order starts when file arrivesis detected, not when after the file is completly written

<mscgen>
msc {

 width1. "800";

FileSystem,JobScheduler,Order,JobChain;

  JobScheduler> FileSystem [labelh1. "(1) start file watching"];
  FileSystem ... JobChain [label "watching for files "];

FileSystemh1. > JobScheduler label "(2) file arrived";

  JobSchedulerh1. > Order [label "(3) start order processing"];
  Orderh1. > JobChain [label "(4) start node"];
  JobChainh1. > JobChain [label "(5) start next node(s)"];
  JobChainh1. > Order [label "(6) end jobChain"];
  Orderh1. > JobScheduler [label "(7) process file sink"];
  JobSchedulerh1. > FileSystem [label "(8) delete/move file"];
  FileSystem ... JobChain [label = "repeat watching for files "];

}
</mscgen>
