Chapter 13. Disk Space Management 13-3
Secondary Allocation
BIM-EPIC automatically allocates secondary extents to eligible datasets when the primary
extent has been filled.
Secondary allocation is not available for direct access or TYPEFLE=WORK datasets.
Secondary allocation is available for SORTWK datasets only if the SORT program
specifically allows it.
For cataloged datasets, you can specify the size of the secondary extents and the maximum
number of secondary extents (up to 255). If you use DD statements for your disk datasets, the
size of the secondary extents can be specified in the SPACE parameter, and the maximum
number of secondary extents can be specified in the VOLUME parameter. If you do not
define a dataset’s secondary allocation requirements in one of these ways, BIM-EPIC
automatically allocates up to 255 secondary extents, and each extent will be one-half the size
of the primary extent.
