Duplicate dump requests

You can code more than one dump request in a job step using DD statements that have different ddnames. When you do this, the system uses the last dump DD statement it encounters.

When the system finds dump DD statements with duplicate ddnames, processing is as follows:
  • In a JES2 system, the job fails with message IEA912I.
  • In a JES3 system:
    • If both DD statements request JES3- or jointly-managed devices, the job is cancelled during JES3 interpretation.
    • If only one or neither statement requests JES3- or jointly-managed devices, the job fails with message IEA912I.
