This IBM Redbooks publication provides an overview of HATS 5.0.4 on z/OS. Many of these improvements are available on the distributed platforms as well. Therefore, this publication should be of value to any HATS v5.0.4 user.
This book is intended for IT managers, application developers, system administrators and architects. The topics presented use as examples HATS applications that front-end 3270 programs and run on WebSphere for z/OS. Many of the concepts in this book also apply to 5250 applications, VT applications, and the other WebSphere runtime platforms.
The benefits of HATS are illustrated using examples. Readers then have opportunities to exercise what they have learned by completing hands-on labs.
Deployment examples and considerations are presented. This includes discussion of the performance, scalability and reliability benefits of running HATS applications on z/OS.
At the end of the book, readers should have a fundamental understanding of the product and be able to create, customize and deploy a HATS application.
