  • An Order is a JobScheduler object that
    • works as a trigger for a job chain, i.e. it makes a job chain run and it is passed from one job chain node to the next.
    • can include a start event, see Job and order triggers
      • a time based event that is triggered based on a date and time or frequency rule for execution of the order.
      • a file event that is created with the arrival of an incoming file from a monitored directory.
      • an external event that is triggered from some application via the JobScheduler XML Interface or from the command line.
    • can include parameters that are used in subsequent jobs: 
      • such parameters are available to all job nodes in a job chain. 
      • parameters can be overwritten, deleted or new parameters can be added to the order at each job node.
      • all the order parameters are also available as environment variables, thus an order parameter added by a Java application job will be accessible to a shell script job or a PL/SQL script job.
  • An order can start from any step (default is first step) in a job chain and end at any step (default is last step/end node). It can also skip part of the job chain according to specified conditions.
  • JobScheduler assigns each order run a unique ID. This is exposed by the SCHEDULER_ORDER_HISTORY_ID environment variable and the order.history_id read-only API property.

Order Example

The screenshot below shows a typical, simple order, configured using JOE - JobScheduler Object Editor.

The order has two main sets of configuration elements, parameters and the run-time configuration:

  • The parameters in this example include the remote JobScheduler the order is to be executed on and information for the tasks to be carried out.
  • The run-time configuration elements specify when the job is to be run.
