You have multiple job steps that require access to the same dataset. How can you efficiently define the DSN for these steps to avoid redundancy and errors?

  • Allocate the dataset separately in each job step to ensure independence.
  • Define the DSN in the JOB statement to make it globally accessible.
  • Use concatenation to reference the same DSN in multiple job steps.
  • Use symbolic parameters in the DSN to represent the dataset name and reference these parameters in each job step.
To efficiently define the DSN for multiple job steps accessing the same dataset, using symbolic parameters in the DSN is a recommended approach. Symbolic parameters allow you to represent the dataset name as a variable, reducing redundancy and the risk of errors. By referencing the symbolic parameter in each job step, you ensure consistency and make it easier to update the dataset name globally if needed. Concatenation is not used for referencing the same DSN in multiple job steps.
