Hi !
A SYSCTL DD card is used to run a batch job under a given CV. The dataset name indicates which CV the job is to run under (e.g., IDMS.CV20.SYSCTL, IDMS.CV30.SYSCTL, IDMS.CV40.SYSCTL). No DD cards are required for the areas used by the program because all areas are controlled directly by the CV.
CV batch jobs require less region to run in than local jobs because the subschema and DMCL are loaded into CV storage instead of the job's own region.
If you watch the batch job's progress under TSO SDSF, you might see it swapped out a good deal of the time. This is normal, because most of the I/O and CPU resources are being consumed by the CV, not the batch job itself.
For more Information plse have a look at the IDMS Programmers Handbook Batch-jobs
