Introduction:
The OS/390
operating system maintains information on catalogued data
sets in VSAM and ICF (Integrated Catalog Facility) catalogs.
In addition, the VSAM access method provides services for
all forms of data set manipulation. The Access Method
Services utility (IDCAMS) provides the services necessary to
create VSAM data sets and manipulate catalog contents.
This course is intended for users who will actively use
Access Method Services from either the TSO or batch
environment of MVS. It covers the JCL needed to invoke
Access Method Services and complete details on the commands
used to request it's utility services. In addition, it shows
which utility services apply to non-VSAM data sets. To
provide the student with a background in VSAM data
structures, an overview of VSAM data organization is
provided. This course has hands-on exercises, and access to
TSO terminals will be required.
Audience: Programmers, end-users, help-desk personnel,
or operators who have a need to access, create or manipulate
VSAM data sets or catalogs in an OS/390 system.
Objectives: On completion of this course, the student
should be able to:
- Create VSAM data sets,
alternate indices and paths
- Catalog non-VSAM data
sets and define generation data groups
- Print the contents of
VSAM and non-VSAM data sets
- Make back-up copies of
VSAM and non-VSAM data sets
- Export and import VSAM
data sets between systems
- Print information from
VSAM and ICF catalogs
Prerequisites: The student must have a working knowledge of
computer fundamentals, MVS JCL and MVS concepts. These
requirements can be met by attending the OS/390 Concepts and
Facilities and
JCL for
End-Users
courses.
Duration:
This course is
4 days long.
