The Job Chain, Jobs and Orders
The
...
Parent Order
The Parent Order, in this example, with ID main_order has the following configuration
- The left branch is used by an Order (main_order) that proceeds over the Join Job and Job B to the end of the Job Chain (state: success).
- The right hand branch is used by an Order (main_order_add-order) that starts at Job A and ends at the Join Job.
To run the example, start the main_order Order.

The test Order starts the first Job (job_create_ordersgenerate) in the joby_chain_test join Job Chain:
- this Job contains a script that generates the orders the Child Orders (see line XX of the listing) for the branch of the Job Chain from the job_nix Job to the join Job.
...
As the end_state for the generated Orders is the join Job state, these orders will be registered by the join job and counted towards to the value set by the job_create_orders shell script in the for loop (10... parameter (12)
