The Job Service is a process that runs on the Centric 8 Application Server, to execute different background jobs. The Job Service is single threaded and can execute only one job at a time.

There are several built-in jobs in Centric 8 and each ${Customer.Name} can add their own export or import jobs. Each Job has a scheduler, that instructs the Job Service on when to execute it.

The Job Service cycle follows the following simple logic:

1. Query for all Jobs in the DB.
2. For each job check if it is due.
3. If job is due, execute it.
4. Repeat steps 2-4 until all jobs are executed.
   

NOTE: In the Cluster environment only one instance of the Job Service can be active.
