• Job Streams are a means to implement dependencies with jobs. This feature improves existing forward dependencies (job chains) by introducing backward dependencies (conditions).
• Job Streams bring a number of new objects to the user interface: 
  • Events
    • Events are tokens that are created on-the-fly to signal execution of jobs. Such Events can be used later on by successor jobs to check conditions that result in the current job being executed or not.
  • In Conditions
    • A job can have a number of In Conditions that control if the job will be executed. Therefore an In Condition includes a number of Expressions that are evaluated to become true or false. The result true will cause a job start, the result false will not cause a job to start. Therefore a false result of an In Condition will put on hold the Job Stream, i.e. further execution of subsequent jobs.
    • Expressions in In Condition typically check the existence of Events. A number of Events can be evaluated including logical operators such as And, Or.
  • Out Conditions
    • A job can have a number of Out Conditions that are checked after job execution.Out Condition include a number of Expressions and depending on the result of the check an Out Condition adds or deletes an Event that can be checked by In Conditions of later jobs.
    • Expressions in an Out Condition typically check the result of job execution, for example, checks the return code of job execution.
• A graphical representation of Job Streams is available with JOC Cockpit to monitor job execution and to manage conditions and events.
  • Using the Job Streams view in JOC Cockpit offers three types of display
    • Image Added
    • The left symbol (highlighted) displays the graphical view.
    • The middle symbol displays the card view.
    • the right symbol displays the textual view similar to what you see from the Jobs view.

• For a good understanding of Job Streams the user should

  • know the technical terms like what is Job and Job Chain etc. and know how to work with JobScheduler Master and JOC Cockpit. 

  • not start with this article if you are new to the JobScheduler. In this case please start with the Product Knowledge Guides.
  • have basic knowledge on how to create the jobs.
