Labs – SDSF (z/OS) 2.5


3 hours



The SDSF labs provide a range of exercises that can be run in your organization’s mainframe training sandbox. Initial exercises focus on configuring SDSF screen defaults and then move on to managing batch jobs and their output using a number of SDSF options. Several exercises relating to searching and saving data from system and user logs are also provided. The last two exercises are for more experienced personnel and deal with JES2 initiator manipulation, and locating data that can assist if there is a JES2 resource shortage.


The majority of exercises are suitable for those that use SDSF to display and manage batch jobs and output, while later exercises are more appropriate for senior operators or System Programmers.


A solid understanding of SDSF or the successful completion of the following Interskill courses:

  • SDSF – Introduction and Basic Concepts 2.5
  • SDSF – Working with SDSF Data 2.5
  • SDSF – Job Activity Basics 2.5
  • SDSF – Controlling and Managing Jobs 2.5
  • SDSF – Advanced Job Management and Monitoring 2.5
  • SDSF – Using SDSF to Display and Control Job Output 2.5
  • SDSF – Advanced – Tips and Tricks 2.5

Note: Each Lab below contains its own list of prerequisites or equivalent knowledge, which is displayed when accessing the module.


After completing these Labs, the student should be able to:

  • Display and hide the SDSF action bar, and screen display options
  • Identify jobs that are held, and release them
  • Identify job delays
  • Access held and non-held output and perform filtering on screen results
  • Sort output based on SDSF screen criteria
  • Manipulate output attributes
  • Purge unwanted output
  • Search SDSF logs for data
  • Print and save log data
  • Display and manipulate JES2 initiator attributes
  • Display JES2 job-related resource usage
