z/OS JCL Workshop Part 2 - Advanced Functions & Utilities

Objectives
On successful completion of this course, attendees will be able to:

• code jobs to run on systems other than the local host
• code JCL statements to create PDSE library and data files
• code JCL to create VSAM data sets without IDCAMS
• use the OUTPUT statement more fully
• describe the function of various batch utilities
• code and execute nested procedures
• use the INCLUDE statement to ease JCL maintenance
• use the SET statement to resolve job wide variables
• describe how SET is used by z/OS when commands are issued to invoke jobs
• code and execute SORT.

Who Should Attend
Systems Programmers, Programmers, Operations Analysts and Operators.
Prerequisites
A good knowledge and understanding of MVS JCL. This can be gained by attending RSM's course z/OS MVS JCL Workshop.

Contents
JCL Review
A quick review of basic JCL.


JES Control Statements
Describes JES2 and JES3; JES2 statement syntax; JOBPARM; MESSAGE; NETACCT; NOTIFY; OUTPUT; ROUTE; SETUP; SIGNON; SIGNOFF; XEQ; XMIT.


JCL Command Processing
Command authorisation; JES2 commands; z/OS commands; COMMAND statement; sample exploitation.


Remote Batch Execution
Routing a job to process on a system other than the one on it was submitted. Security and remote job execution.
This segment gives a brief overview of RJE and covers the security aspects of remote job submission.

Output Processing
Using JOB statement; Using JOBPARM; using OUTPUT; using ROUTE; using DD statement; OUTPUT JCL statement.


Partitioned Data Set Extended (PDSE)
What is PDSE; types of PDSE; PDSE concatenation; PDSE restrictions; IDCAMS & PDSE; PDSE in JCL.
This segment describes how to create PDSE, and HFS files. It also describes how to create VSAM datasets directly, without IDCAMS.

IBM batch utilities
IEHINIT; IEHLIST; IEHPROGM; IEBCOPY; IEBDG; IEBGENER; IEBPTPCH; IEBUPDTE; IEFBR14; IDCAMS; IDCAMS; ICKDSF
Covers the usage of the various utilities, including when they may be required instead of using TSO/E functions.

z/OS DFSMSdss
Dataset compression; defragmentation; dumping; restoring.


Advanced catalogue procedures
Nested procedures; INCLUDE statement; SET statement; automatic invocation of jobs.
Describes the concept of nested procedures and how they are coded. It offers an approach to using the INCLUDE statement to ease JCL maintenance and improve support staff productivity. It also describes how the SET statement can be used to resolve job wide variables and explores the process of starting jobs and procedures via a start command.

Sub-system interfacing
What is a subsystem; CNTL & ENDCNTL statements
This segment describes the OUTPUT statement in some depth, and compares with other options. It covers the relationship with other network printing facilities such as Printway/IP.

Using SORT
Describes how the SORT program can be used to selectively process records in a dataset.
This segment describes SORT control statements in some detail, particularly the INCLUDE and OMIT statements.
