It would be difficult to name a function or capability in z/OS that does not involve some change to SYS1.PARMLIB. Want to enable a new function? Update Parmlib. Want to ensure that your system setup reflects IBM’s latest best practices? Update Parmlib. Get it?

What will I learn from this one-day class?

• Over 130 enhancements and new features affecting Parmlib that were delivered by IBM in z/OS 1.13, 2.1, and 2.2.
• Reasons for the change, the associated function or capability, what environments it is appropriate for, and our recommended values.

Did you know that most new functions are turned off or disabled when initially installed? Many of these functions will help you save money, reduce time, or improve reliability.

Seen our articles on Parmlib enhancements in our Cheryl Watson’s Tuning Letter? This class will get into much more detail about each parameter and keyword. We will ask you to bring your own Parmlib members, and we’ll help you understand and review the settings in your installation.

What is the class objective?

Get the full value out of your z/OS system by making you aware of all the Parmlib changes that were delivered in z/OS 1.13, 2.1, and z/OS 2.2.

One of the cornerstones of z/OS is upward compatibility. And the number one priority when you migrate to a new release is typically to ensure that everything that worked with the old release still works with the new release. As a result, the default mode of operation is that enhancements or new functions tend to be shipped by IBM in a disabled state.

Already running z/OS 1.13?

Use this class as a health check to ensure that you are actually exploiting all the capabilities that are available to you.

Already migrated to z/OS 2.1?

If you’ve made the migration or are working on a business case to justify the migration, this class will help you identify all the functions that are applicable to your environment, including those that were shipped in z/OS 1.13 that you might have overlooked.

How do I know if this class is right for me?

This class is great for z/OS System Programmers and anyone who is responsible for planning and implementing a migration to z/OS 1.13, 2.1, or z/OS 2.2. To get the best value from this class, students should have at least two years experience as a System Programmer, and be familiar with the functions that are enabled in your environment, the products that you are using, and the challenges and goals of your production environment.

Did you know, very few classes are taught by the people who actually develop them?

Ours is an exception.

Cheryl, who has 50 years experience in mainframes, is best known for her Cheryl Watson’s Tuning Letter, and her award winning conference presentations. She has developed and taught classes in performance management, capacity planning, outsourcing, chargeback, workload manager, and parallel sysplex.

Frank Kyne, who has 35 years experience in mainframes, is best known for his work in IBM’s ITSO organization as well as writing and creating over 80 Redbooks. He was a very popular class developer and teacher for the ITSO workshops given around the world. IBM customers frequently requested Frank for resolving parallel sysplex problems. He is currently the editor of Cheryl Watson’s Tuning Letter, gives award winning conference presentations, and has a suitcase full of Irish jokes.

This class is developed and instructed by Cheryl Watson and Frank Kyne.
