4 hours



The SDSF – Using SDSF to Work with System Information and Devices course describes how to display the contents of spool volumes, and manage spool volume availability. It explains how a spool offload is performed when data needs to be moved from spool devices. Tasks associated with displaying and managing JES2 nodes and lines is presented, and the process of obtaining a wide range of system information and defaults is also covered.


Operations and programming staff that use SDSF to monitor and manage JES2 resources.
