To prevent time sequence gaps in CDS records, perform the following steps:
If a successful completion code is not received for the creation of the output data set, the job ends, and the input data set is not created.
If your CDS is currently too small and you want to change that, the next time you reorganize the data set, add 10 cylinders. If the data set is still too small, the next time you reorganize add another 10 cylinders. Do this until the data set is large enough that the need for reorganizations is infrequent.
For more information about reorganizing your control data sets, see the topic about reorganizing the control data sets in z/OS DFSMShsm Implementation and Customization Guide.
