CTDDELRP Deletion Rules

Control-D and Control-V reports are identified by user entries, SYSDATA entries, and CDAM compressed data sets. Each user entry can point to one or more SYSDATA entries. Each SYSDATA entry points to one CDAM data set. Each CDAM data set is pointed to by one or more SYSDATA entries.

When deleting reports, CTDDELRP maintains the integrity of this data structure according to the following rules:

• A CDAM compressed data set is deleted when all SYSDATA entries pointing to it are deleted.
• A SYSDATA entry is deleted when all user entries pointing to it are selected for deletion.
• A user entry is deleted:
  • when all SYSDATA entries to which it points are selected for deletion, or
  • when every SYSDATA entry to which it points no longer exists, meaning, the SYSDATA entries were deleted using the Control-D or Control-V Online facility

The CTDDELRP utility issues a message if it finds a SYSDATA entry that is not pointed to by any user entry, meaning, the user entries were deleted using the Control-D or Control-V Online facility. If parameter NOREPORT was specified, this SYSDATA entry is automatically deleted.
