Special Note
 
Learn how to use z/OS Job Control Language (JCL) and selected utility programs in an online batch environment. Both Storage Management Subsystem (SMS) and non-SMS JCL are discussed. Hands-on lab projects may be done in teams depending on the number of attendees and location.


Hands-On Labs

Six labs are included to address multistep jobs; reading and printing instream data; temporary data sets; use of IEHLIST utility; use of IEBGENER utility; use of IEBCOPY, JCL procedures; creating SMS and non-SMS data sets including, Partitioned Data Set (PDS), Partitioned Data Set Extended (PDSE), Virtual Storage Access Method (VSAM) and Hierarchical File System (HFS) data sets; and compile, link and go.

  • code and discuss the DISP parameter
  • use special DD statements
  • detect and correct JCL syntax and usage errors

Introduction to utilities and conditional execution

  • identify the different types of utility programs
  • establish the rules for coding utility control statements

Generation Data Groups (GDG)

  • describe when a GDG is needed  
  • code DD statements to utilize a Generation Data Group in both single and multiple step jobs
  • discuss the differences between the relative data set name and the absolute data set name

Procedures

More about utilities

  • look at examples of more utility programs: IEBGENER, IEBCOPY, IEHLIST, IEHPROGM, IEBUPDTE
  • use the DFSMSdfp Utilities manual for reference

More on procedures

  • compare the PROC, EXEC, and SET statements for supplying symbolic parameters

Selected JCL topics

  • describe conditional execution of job steps using the IF/THEN/ELSE/ENDIF statement construct
  • code the parameter to control the amount of output to be printed and the timing of the printing
  • use the OUTPUT statement to route SYSOUT to multiple nodes and to establish default forms control for SYSOUT data sets
  • describe the NOTIFY parameter

Sort/merge

  • describe the Sort and Merge processes
  • describe the JCL and control statements required for a SORT or MERGE operation

  • describe the characteristics of IBM standard tape lables
  • code tape label processing options on the DD statement
  • code DD statements to allocate and locate a multivolume tape data set using single and multiple tape units
  • discuss the types of tape drives and methods of requesting them
  • explain the differences among tape label types
  • code DD statements utilizing the UNIT=AFF=DDNAME parameter to reduce device requirements

ABENDs

  • define the term ABEND
  • recognize the causes of system ABENDs
  • identify the basic steps in problem determination and recovery
  • use the system codes and messages manuals to aid in performing and a printed output data set
