Cylinder Index z/OS DFSMS Using Data Sets SC23-6855-00 |
|
For every track index created, the system generates a cylinder index entry. There is one cylinder index for a data set that points to a track index. Because there is one track index per cylinder, there is one cylinder index entry for each cylinder in the prime data area, except for a 1-cylinder prime area. As with track indexes, inactive entries are created for any unused cylinders in the prime data area. |
