Tutorial Recommendations
Hands-on is the Best Way to Learn
It is recommended that students logon to z/OS and should attempt the hands-on demonstration
examples while **reading this tutorial”. The best way to learn z/OS is simply to read the
directions and complete the hands-on requirements. The student should avoid getting distracted
or becoming overwhelmed by a few technical concepts. If the student follows the hands-on
directions, the technical concepts may be easier to understand after you have completed
these hands-on requirements.
Handling Common Errors submitting a JCL Job, using ISPF and SDSF
Z ISPF and File System Tutorial – 2 includes explanations and possible solutions for common errors
using ISPF. It is RECOMMENDED for a student to read these problem solving recommendations and
attempt to resolve your specific problem BEFORE you ask your instructor for assistance. This tutorial
is designed to introduce common ISPF troubleshooting strategies. If after you have read and
attempted to apply these troubleshooting suggestions and you still need assistance, DO ASK YOUR
INTRUCTOR FOR ASSISTANCE. It is important that your personal experience using the fastest
commercial computer in the world will be a success for you.

Requirement 1. Introduction to the Functions of File Systems
A File System is a collection of operating system programs that control the manner in which files are
named, are created (Allocated), stored (Saved), retrieved (Opened), and managed. Most operating
system support one or more file systems. While most file systems are similar, the rules to use each
file system varies. Each file system varies by degree of content flexibility, organization, storage
efficient and performance.
Previous mainframe file systems introduced in the 1950/1960s were designed during a time period
when the cost of a single 30-megabyte disk drive (DASD) exceeded $18,000, and the internal disk
management processor and data transfer rates were very slow. During this period there were no
Word documents, sound and video files, or other modern stored content. The personal computer or
desktop applications did not exist.
The z File system was designed for storage and processing performance and offered almost
no content flexibility. While we may prefer user-friendly, content flexible file system like Windows
NTFSv5 or Linux ext-4, neither of these file systems are as storage or performance efficient as the
IBM z File system for large-scale transaction processing. If you need more user-friendly, content
flexible file system, then it is recommended to use the zUnix or Linux for z System operating systems
or directly use a Windows or Linux server system.
1.1 Naming Files or Datasets
1.1.1 Naming files in the Windows NTFSv5 file system.
A Window’s file or folder may contain up to 255 characters, embedded spaces, and will retain the
case of letters in a file name, but the use of upper and lower-case does not make the file or folder
name unique. For example, .DOCX is the same file name as .docx.
A fully-qualified NTFSv4 file has three major components.
If you do not specify the device or parent folders (the location of the file), Windows NTSFv5 assumes
that the file will be stored or located in the current folder. Backward slashes are used to separate
storage location information from the file name. A period is used to separate the file name for the
File Extension (.DOCX) from the file name. The File Extension is used by the Windows file system
to specify which application understands the content of the file.

1.1.2 Naming z System Data sets
A Window file is similar to a z File System data set. A Data Set name cannot be longer than 44
characters, may not contain embedded spaces, the first character must be a letter, and can be letters,
numbers, sp …
