Configuration file in DataStage is the main element when it comes to the execution of a job. You do not need a configuration file while designing the job however it is needed when you want to execute the job.
How the job will be executed on the available hardware is defined by this configuration file. In other words we can say the degree of parallelism is defined by the configuration file. It provides the logical separation of the available hardware. Configuration file has Nodes, resource pools, scratch area etc. to name.
When a job executes before dealing with the data it makes a reference to the assigned configuration file. You can see the job score where you can find the information similar to what is there in the configuration file.
To conclude configuration file is the integral part of the DataStage.
