Pool addresses can become lost to the system in a number of ways (for instance, application program errors or system failure). The file pool recoup program is provided to recover these lost but still usable pool records. The lost records are made available to the system for further usage. The recoup program must interface closely with the application environment to determine which records are valid. As a result, the user must allocate and initialize the recoup descriptor records which define where the package can find the pool addresses within the user's application fixed file records.
A by-product of the file pool recoup program is information which identifies application programs which may be responsible for not returning file pool records to the system.
MDBF users of the HPO feature may use the recoup package within each subsystem and as a result, the descriptor records must be uniquely defined and allocated for each subsystem.
