Become a VSAM Expert
SYS-ED's VSAM curriculum will make you a VSAM expert. You'll not only learn how VSAM works, but how to make it work well, and what to do if things go wrong. Even if you're already using VSAM, you'll gain a better understanding of its capabilities and flexibility… like how to select among the options VSAM offers for configuring data sets, both batch and on-line. And offer unbiased guidelines derived from our work as leading edge consultants.

Our standard operating procedure is to establish performance objectives, examples, sample programs, exercises, and assessments to be included in the training. This information will be provided to the client in writing.  Equally as important, SYS-ED recognizes and differentiates between industry standard content and educational consulting.

SYS-ED's VSAM training contains up-to-the minute information which keep it line with state-of the-art hardware. Our system consultant instructors average 30 years experience in evolutionary information technology. We teach industry standard content and provide insights on VSAM in relation to IBM's DB2 and IMS databases.

Technology Driven IT Training

VSAM Usage Guidelines

Use alternate indexes sparingly There is a price with alternate access. AIX data is structured around alternate keys and accordingly are difficult to tune. Performance can degrade due to CI: control interval and CA: control area splits.
Keep string number low for ESDS Many applications use an ESDS: Entry Sequenced Data Set as a processing log. On very active systems this means a high number of transactions per second will be vying for access to the file.
Use Local Shared Resource LSR mode allows VSAM to maintain dataset buffer pools to reduce I/O wherever possible through lookaside processing.
Size is important The CI size selected for the data component of the cluster is a balancing act between space and performance. A purposeful calculation of both the number of records in one block along with free space will be required.
Avoid larger CI sizes It will take more processing resources to move around larger chunks of data, VSAM systems locks at the CI level. Therefore, a large CI containing many records is more likely to cause waits.

CICS and VSAM
CICS has options for taking advantage of LSR, and if the virtual storage is above the 16M line the buffer ratio can be increased up to 90%. CICS allows for eight separate buffer pools. Normally one is sufficient, but a very active dataset can be moved into its own pool to prevent its records from crowding out others. Buffers can be specified for index and data control intervals. This provides the opportunity to create an index- only buffer pool large enough to contain all of index CI's which will serve to make keyed access significantly faster. 

Each of our courses - VSAM for Programmers, VSAM Structure and Strategies, VSAM Performance and Tuning, VSAM Optimization Techniques, and Transactional VSAM provide a proven combination of case studies and hands-on workshops. A third of your class time will be spent coding and testing programs and using Access Method Services on our z/OS mainframe system. SYS-ED's  VSAM training supports the full complement of programming languages: COBOL, Assembler, FORTRAN, and PL/1. And we also are experienced with VSAM in a z/VSE operating environment. Vanderbilt Medical Center (z/OS) and University of Northern Alabama (z/VSE) have had us provide educational consultancy on how to optimize VSAM datasets.  Students are encouraged to bring programming and debugging assignments to class for analysis and discussion. After the course, students are welcome to submit questions which come up back on the job.

Learning Paths

   
The VSAM course workbooks and training aids that we provide as part of our instructor-led courses are unique in the IT field. They reflect far more than simply the vendor documentation. Our content and diagrams reflect a careful examination of the architecture, program logic, and include sample programs which have been validated on consulting projects. Reference material which “explains and demonstrates” is fundamental to effective knowledge transfer.

Yes, We Still Offer VSAM Training!

Portfolio: Mainframe Training Services

Over the past year, we have had a number of inquiries regarding whether SYS-ED still offered VSAM training for IT professionals.

The typical comments were:

1. That it is extremely to find VSAM training for specific development and maintenance tasks.
2. That there is a scarcity of fast-track VSAM for Programmers and VSAM Performance and Optimization courses, 3 days or fewer in duration, geared to different operating systems and legacy programming languages.
3. That a high percentage of VSAM courses are cancelled.

VSAM Training in New York

VSAM Courses in New York
SYS-ED's VSAM courses are tough, but they're worth it. Our challenging "hands-on" VSAM training provides a foundation and framework for Fortune 1000 companies, government municipalities, healthcare providers, software houses, and consulting companies to meet their VSAM staffing requirements and acquire specialized VSAM skillsets.1

Courseware
SYS-ED's VSAM courseware is highly acclaimed in the IT field.  We draw upon our extensive library of courseware, sample programs, and case studies to explain, demonstrate, and teach the real-world VSAM. Our VSAM curricula include industry standard and consultancy derived content. We have the capability to provide tailored workshops and integrated training programs on z/OS, z/VSE, z/VM, and third party emulation workbench/platforms.

Teaching is Our Business
Most computer training companies are divisions of large software companies or consulting companies. Not SYS-ED. Our only goal is to provide world class VSAM training for highly motivated IT professionals - no more and no less. Because we're independent, we're free to concentrate on teaching - and since 1980 we have been doing it very well.

Our Teachers Know How to Teach
SYS-ED instructors combine teaching skills with broad practical experience as consultants. Our instructors average 30 years of experience with VSAM in the mainframe environment - operating systems, programming languages, 3rd party utilities/development aids, and system software. And they know how to teach it. We teach not only "how to", but "why", building a solid foundation in fundamentals and insights into advanced materials. After a course, they are available to answer questions.

Enrollment - SYS-ED VSAM Courses are NOT for Everyone
No one is allowed to enroll in a SYS-ED mainframe course, without a consultation with our Director of Education. We review the operational objectives and project specifications for the organization evaluating whether to send its employee for the training. The employee is only allowed to register if they have the appropriate background corresponding to the correct learning path.

VSAM Training in New York or at Your Office
SYS-ED's VSAM courses are held at our modern, fully equipped training center in New York City and in conjunction with training partners in North America and Europe. If you prefer, we'll arrange tailored mainframe training on-site at your organization’s facilities inclusive of mobile computer classroom set-up. On-site mainframe courses can include the identical workshops, case studies, and hands-on approach as the mainframe training we offer in New York city.

For additional information including outlines, availability of private courses, references, and course customization, contact David Shapiro at our New York office at 212-564-9147, 48, 49 or register online.
