Setting

parameters in a PowerShell script and
...
passing them to the next step
...
At every change of status in job chains Job Scheduler parses a temporary file for "namh1. name=value" pairs. The "namevalue" name/value pairs will be set as order paramsparameters for subsequent jobs. The name of the temporary file is available with the environment variable SCHEDULER_RETURN_VALUES. See also Passing_parameters_from_shell-jobs_to_JS for an example showing How to pass parameters to subsequent jobs in a job chain for an example how to pass parameters to pure between shell jobs.
The example below describes a job chain with two steps. Both are running the generic job PowerShellExecutor to presented in How to configure a generic PowerShell job to execute a PowerShell script within JobScheduler.
First Step: set a parameter for the next step in the job chain

Job Chain
the The xml representation of the job _ chain:
| Code Block | ||
|---|---|---|

<job_chain> <job_chain_node state="100" joh1. job="PowerShellExecutor" next_state="150" error_stath1. state="error"/> <job_chain_node state="150" joh1. job="PowerShellExecutor" next_state="200" error_stath1. state="error"/> <job_chain_node state="success"/> <job_chain_node stath1. state="error"/> </job_chain> |
Click the parameter button shown in the image above to specify the parameters for the selected job chain node.
