FORCECAT—force catalog disposition for new data sets

Uncataloged data sets must be manually tracked and can be lost, taking up valuable space on storage devices.

Locating uncataloged data sets might require a lengthy search of all volumes on the system. DFSMS manages only cataloged data sets. Data set cataloging is controlled by the JCL DD parameter DISP, but for non-SMS-managed data sets, z/OS provides no way to require that the appropriate value of DISP is used.

For new data set allocations, FORCECAT forces the data set to be cataloged, regardless of the value of the DISP parameter in the JCL.
