Description:
Fetch an environment variable from the application server.
Inputs
- name – provide a step name
- envvarmappings – environmental variable mappings
Returns
- True – step executed successfully
- False – step failed to execute
Usage:
Example:
Let’s build and execute the readEnvironmentVariablesDef example.
- Create a new definition called “readEnvironmentVariablesDef”
- Select the definition and click the “design” button
- Drag a “readEnvironmentVariables” from the toolbox
- Connect the dots between the start and “readEnvironmentVariables” step
- Define a variable/global to store the result after execution
- Click on the "readEnvironmentVariables" step to configure its "Settings" properties. Provide a name to the step. Click on button to configure environmental variable mappings.
- Provide the environmental variable name to fetch from the application server. Provide the variable/global to store the result. Click on Add Row button to include more. Click on Save to confirm the action.
- The “Logging” setting configuration is necessary for documentation and also measure the workflow progress and the percent complete. This is acheived by configuring the step state and percent fields individually as shown in the images below. Configure the “Logging” using the following properties.
- Save the process definition, create a new process instance and execute. Render the process instance. Click on the “readEnvironmentVariables” process step to view the properties. The step should get the environment variable value defined in the Windows system (previously set by the “setEnvironmentVariables” process step).
Create or modify environment variables on Windows 10:
- On the Windows taskbar, right-click the Windows icon and select System.
- In the Settings window, under Related Settings, click Advanced system settings.
- On the Advanced tab, click Environment Variables to view the list of variables and their values in the list.
