Parameter Sets

There are three primary ways to create a parameter sets and is a different practice from adding ‘User Defined’ variables in InfoSphere DataStage Administrator. The ways to create a parameter set are:

• Create a parameter set from a data connection stage
• Create a Parameter Set from the navigation of DataStage designer, and
• Create a Parameter Set from a job

Create a parameter set from Data Connection Stage

This is used to create parameter sets for Database connections parameters

To create a new Parameter Set from a Data Connection

• Select: File > New > Other and select “Data Connection“
• Complete the data Connection stage properties, then save the stage.
• Open the Connection stage and navigate to the “Parameters” Tab
• Then, click on the “Associated Parameter Set” button, and Chose the “Create & Attach” menu item
• This will Launch a Dialog
• Fill out the appropriate information on the General tab and the proceed to the Parameters Tab:
• In the Parameters Tab, enter in the Parameters you wish to include in this Parameter Set
• On the Values tab, specify a Value File name (please follow naming convention standards to prevent rework and other problems). This is the name of the file that will automatically be created on the Engine tier. This tab also allows you to view/edit values located in the value file.
• Click OK to save the Parameter set.

Create a Parameter Set from the navigation of DataStage designer

This is, perhaps, the more traditional way of creating a parameter set.

To create a new Parameter Set

• Select: File > New > Other and select “Parameter Set”
• This will Launch a Dialog
• Fill out the appropriate information on the General tab and the proceed to the Parameters Tab:
• In the Parameters Tab, enter in the Parameters you wish to include in this Parameter Set.

• Create a Parameter Set from a job
  On the Values tab, specify a Value File name (please follow naming convention standards to prevent rework and other problems). This is the name of the file that will automatically be created on the Engine tier. This tab also allows you to view/edit values located in the value file.
• Click OK to save the Parameter set.

This approach is, perhaps, less traditional, but is equally effective, if you find yourself creating additional jobs and now need to share the same parameters.  This is a quick and easy to generate a parameter set from an existing job.

To create a new Parameter Set from a job

• Open the job that you want to create a parameter set for.
• Click “Edit > Job Properties” to open the “Job Properties” window.
• Click the “Parameters” tab.
• Press and hold the Ctrl key, then select the parameters that you want to include in the parameter set.
• With your parameters highlighted, click “Create Parameter Set”.  The Parameter Set window opens.
  • Enter a name and short description for your parameter set.
  • Click the “Parameters” tab; the parameters that you selected are listed.
  • Click the ”Values” tab.
  • Enter a name in the Value File name field, then press Enter.  The value for each of your parameters is automatically populated with the path name that you entered.
  • If a default value is not already set, enter a value for each parameter. For example, if the variable is a Pathname type, enter a default path name.
  • Click “OK” to close the Parameter Set window.
  • In the Save Parameter Set As window, select the folder where you want to save your parameter set and click Save. When prompted to replace the selected parameters with the parameter set, click Yes.
• Click “OK” to close the Job Properties window.
