|Abstract: Couple Data Sets (CDSes) are the cornerstone of Sysplex. Careful planning is required to ensure CDSes are always available, never corrupted and never misused such that they trigger a high-impact failure scenario. This paper documents the best practices for CDSes. The paper also documents known field reported issues associated with CDSes. System programmers can use the paper to update enterprise processes to best practice and avoid disasters through increased understanding of CDS handling.|
