CTDCCU – Delete Unneeded CDAM Files

The CTDCCU utility identifies CDAM files that are not referenced by the Active User Report List file (as SYSDATA entries) and optionally deletes them.

CDAM files created using the JCL parameter SUBSYS are not always decollated. Since they are not referenced by the Active User Report List file (ACTUSR), CTDDELRP does not delete these CDAM files. This utility identifies or deletes these CDAM files.

This utility also identifies, and optionally deletes, Control-V index files that are not referenced (as INDEX entries) by the Active User Report List file or the Migrate User Report List file. Since they are not referenced by a Control-V database, they cannot be deleted by the CTDDELRP, CTVCLMIG, or CTVDELI utilities.
