In contrast with job parameters, job chain node parameters are independent of the the job specified for a job chain and thereby allow . Their use provides a greater degree of flexibility in job chain configuration than can be achieved with job or order parameters. Order parameters . Using job parameters means the are - logically - tied to an order and have to be redefined each time an order is created. Similarly, job parameters are tied to a job. This means that if a job is to be used at multiple steps in a job chain or in different job chains, multiple instances of that job will have do be defined if different parameters are to be set each time the job is to be run, even though it is the same job implementation is being used each time.
Usage example
The following example shows a simple situation that illustrates As an illustration of the flexibility brought with job chain node parameters., consider the following simple example:
For Consider a job chain made up of three stepsnodes:
- transfer a file by FTP to host a,
- transfer a file by FTP to host b,
- delete file.
Job the use of job chain node parameters would allow the same job to be used for both steps nodes 1 and 2 but with different parameters each time.
