The STATS reports provide statistics about DLF activity. If DLFDATA STATS(class) is specified, the report shows statistics information only for the class.

The STATS report contains sets of selected DLF values. The first set of values in the report, after the class name, are the maximum resource values that were specified in a COFDLFxx parmlib member.

Following the maximum parmlib values are the amounts of each resource that were in use at the time of the dump. After these current values, selected connect statistics appear in the report followed by selected object statistics.

The connect statistics that appear include the total number of connect requests that were successful, the total number of requests that failed, and the maximum number of connects that were active at the same time. The system has accumulated these values since the system last started DLF.

The object statistics that appear include the total number of objects currently connected and the total number of objects that have no connected users but still exist in DLF. The system has accumulated these values since the system last started DLF.
