Lesson 2.5: Creating a parameter set
In the previous lesson, you created parameters for your job. To further simplify your job design and runtime operations, you create a parameter set and store it in the project repository. You can then reuse the parameter set in other job designs.
About this task
Overview
When you create the parameter set, you enter a set of default values for the parameters that are input at run time.
You use parameter sets to define job parameters that you might reuse in other jobs. When you want to use these parameters in a job, you insert them into the job properties from the parameter set. You can create parameter sets from existing job parameters, or you can specify the job parameters when you create a new parameter set.
You can also define different sets of values for each parameter set. Parameter sets are stored as files in the InfoSphere® DataStage® server installation directory and are available to use in your job designs or when you run jobs that use these parameter sets. If you make changes to a parameter set object, the changes are reflected in job designs that use this object when the job is compiled.
Procedure
Before you begin
Procedure
What's next
You created a parameter set that is available for another job that you create later in this tutorial. The current job continues to use individual parameters rather than the parameter set.
- Created your first job and added stages and links to your job
- Set stage properties that determine what actions occur when you run your job
- Imported metadata to use throughout your job
- Created a parameter set from a set of existing job parameters
- Specified a set of default values for the parameters in the parameter set
- Created a parameter set that you use in a subsequent job
