Ensure accuracy and reliability of your SMS configuration

SMSDEBUG provides the z/OS storage administrator with an invaluable tool for ensuring the accuracy and reliability of one of the system’s most critical resources – the SMS Configuration. SMS controls the creation, attributes, and placement of every single file in the system, as well as all disk and tape volumes and backup and migration policies. Despite its importance, however, the SMS configuration is often badly neglected – ancient ACS routines remain unchanged and untested, and incorrect, redundant, or obsolete construct proliferate, resulting in misallocations, poor storage use, and job failures. With SMSDEBUG, storage administrators can be certain that the SMS configuration is accurate and up-to-date. Read more about SMSDEBUG.
