Short overview about Orders:

Overview

  1. An orders is a JS element which works as a "Token". An order is passed from a job chain node to the next node or to multiple nodes (parallel orders) in case of parallel job chain configuration (Nodeh1. Job Step).
  2. An order can have following configuration elements:
    • runtime configuration date/time/frequency
    • parameters i.e. cutoff-date, database connection information etc.
    • target server name/ip address for job chain execution, the default is localhost
  3. An order primarily carries parameters which could be used by specific job nodes or by all the nodes of the job chain.
  4. An order also carry runtime configuration i.e. date/time/frequency etc.
  5. An order can be configured to start part of job chain on one server i.e. Server-A and part of job chain on a second server i.e. Server-B.
  6. An order can be also configured to start a locally configured job chain on a remote server, so one can create a generic job chain and create multiple orders for that job chain. An order in turn can contain ( optionally) the server name, a runtime configuration and extra parameters required for jobs.
  7. An order is also a "stateless" object, which means that orders do not have success or error states. State is a job property.
  8. An order can start from any step (default is first step) in the job chain and end at any step (default is last step/end node)or can skip part of job chain depending upon specified conditions.
  9. JS can also create orders from a file-watcher i.e. a job chain can be configured to monitor any directory for incoming file(s), once a file matching with regular expression is found JobScheduler creates order to start the file processing.
  10. An order carry parameters from one node to another, parameters can be overloaded, deleted or new parameter can be added to the order by each node.
  11. All the order parameters are also available as environment variables, thus order parameter added by Java application job will be accessible to shell script job or even to PL/SQL script job.
