Learn how you can leverage VSAM Recording Level Sharing (RLS) best practices and performance.  The best practices will include tips to detect, SMSVSAM issues, what documentation to collect, and finally how to resolve issues with the minimal amount of impact to the overall production cycle. Also covered are ways to optimize VSAM RLS usage, and how to correctly size your VSAM RLS cache and buffer sizes to make optimum use of features made available through VSAM RLS.  Using real life examples of Performance statistics and how they affect your environments, you can see what a properly tuned SMSVSAM setup looks like, compared to one which is running under constrained conditions.  In addition, changes will be explained that can be used to correct performance issues.  Learn how understanding how your shop accesses data can be leveraged to make a better SMS VSAM environment.   David Legendre, IBM Corporation
