Image-related data sets

These data sets contain unshareable system image information. Although the recommendation is that they be put on separate volumes, as described in this topic, if DASD is scarce you can combine them at the expense of performance or availability, or both.

Image-related data sets should use system symbolics in their names for easier maintainability. For more information on system symbolics, see z/OS MVS Initialization and Tuning Reference.
