z/OS Communications Server: Index of Educational Presentations

Education

Abstract

Several times each year, members of the z/OS Communications Server team--including development, test, and support--create and present education sessions for IBM customers. These sessions are recorded and published in IBM documents available online. This index serves as a repository of links to these documents.
