JobScheduler can reference job chain node parameters - i.e. parameters that are valid for a specific node in a job chain.
Job chain node parameters can be defined for orders and for the job chain:
- Job chain node parameters for orders are defined in a similar manner to conventional order parameters - but using a special syntax.
- Job chain node parameters for the job chain itself are defined ina job chain parameter file. The jobs in the job chain use a special monitor to read the job chain parameter file.
Job chain node parameters for both orders and for the job chain The parameters in the job chain parameter file can reference other (global) parameters.
Usage Notes
The flexible use of parameters possible with In contrast with job parameters, job chain node parameters cannot be achieved using normal order parameters. It could be achieved by using job parameters but if the same are independent of the the job specified for a job chain and thereby allow a greater flexibility in job chain configuration than can be achieved with job or order parameters. Using job parameters means the if a job is used at multiple steps in a job chain or in different job chains you would have to define multiple instances of that job , although have do be defined, even though it is the same job implementation is being used each time.
Usage example
The following example shows a simple situation that illustrates the flexibility brought with job chain node parameters.
Consider For example, if a job chain consisted made up of three steps:
- transfer a file by FTP to host a,
- transfer a file by FTP to host b,
- delete file.
You could use the The same job could be used for both steps 1 and 2 using different parameters for each job.In the current example the same job will be used twice but with different parameters each time.
