In an MVS environment, a predefined number of dump datasets is defined and allocated. These files are named SYS1.DUMPxx. Whenever any system component produces a dump, it is directed to one of the empty (available) dump files.
If all dump files are full, the current dump cannot be produced and important information may be lost.
This solution is designed to ensure that a pre-specified number of empty dump datasets is always available for new dumps. The solution responds to MVS messages that indicate that no dump datasets are available, and after a dump has been produced, it checks that there is still a sufficient number of empty dump datasets.
