VSAM – Defining, Altering, and Deleting VSAM Data Sets z/OS 2.5
This course describes how VSAM data sets are created using the IDCAMS Utility, or by using JCL statements. It also discusses how alternate indexes on creating, copying, deleting, and managing VSAM data sets using JCL, TSO/E commands, the IDCAMS batch utility, and other tools is also covered. Finally, other products used to manage VSAM data sets are introduced – both from IBM and other vendors.
