Implementation Considerations

Implementing a Physical Sequential data set commonly involves analyzing the data set, choosing a compression method and defining it to the Control File, just as in the case of the VSAM Transparency, with certain minor differences. You can run the CFMU yourself to define the data set, but the IUI analyzes the data set and can normally tell whether it is already compressed or not, and with which algorithm, which helps you to insure that the data set is defined correctly.
