In the world of mainframe development, mastering legacy systems is crucial for maintaining and evolving critical business applications. For those working with IBM’s Information Management System (IMS) on z/OS, finding a comprehensive and practical learning resource can be a challenge. Fortunately, the “IMS DB ON z/OS – Full course – Information Management System” on Udemy offers a deep dive into this powerful database system, equipping developers with the skills needed to excel.
This course is meticulously designed to provide practical proficiency in IMS DB development. Whether you’re looking to gain a thorough understanding of your existing project programs or build new ones from scratch to meet client demands, this course delivers. The instructors guide you through the intricacies of IMS DB, starting with fundamental concepts like what IMS DB and IMS DC/TM are, and progressing to a developer’s perspective on IMS DB architecture and components.
The curriculum covers the essential IMS DB data model, focusing on hierarchical data structures, segments, fields, and the relationships that define them. A significant portion of the course is dedicated to IMS DB programming interfaces, including an introduction to DL/I (Data Language/I) and the critical Program Communication Block (PCB). You’ll learn about various IMS DB calls and APIs, and crucially, the different organizations and access methods such as HSAM, HDAM, HISAM, and HIDAM, with clear explanations of their differences.
One of the standout features of this course is its practical approach. It includes demos on creating IMS DB structures, segments, segment types, fields, and database paths. The course also delves into DL/I terminology, control blocks, and provides DBD (Database Definition) creation examples. Understanding the difference between PSB (Program Specification Block) and PCB is clarified, alongside basic IMS DB operations like reading, writing, updating, and deleting records. The inclusion of demos showing how to write IMS DB and COBOL programs is particularly valuable for hands-on learning.
Furthermore, the course tackles crucial aspects of debugging and error handling. You’ll learn about Qualified and Unqualified Segment Search Arguments (SSAs), the Program Communication Block (PCB) in detail, and effective IMS DB error handling techniques, including dealing with abends. Debugging strategies tailored for IMS DB programs are also thoroughly explained.
**Recommendation:**
For any developer involved with IMS DB on z/OS, this Udemy course is an invaluable resource. Its structured approach, from foundational concepts to advanced programming and debugging, makes it suitable for both beginners looking to enter the IMS world and experienced developers seeking to deepen their knowledge. The practical demonstrations and clear explanations of complex topics make it a highly recommended investment for anyone serious about mainframe IMS development.
