Appendix B. Mapping ISV Products and Functions

This is a frequent topic of discussion with customers considering migrating. How a customer′s ISV products map to those contained in base OS/390 is always discussed.

It is a common migration task to ensure there is equality. This equivalent function mapping will grow in importance as coexistence is established.

It is also a way customers can reduce their ISV SW stack charges. Also if customers are not familiar with the comparable functions of each operating system it provides a good guide and helps when it is time to configure the OS/390 system.

This mapping information also fits in with the description of system management products listed in 2.2, ªOS/390 Components/Products/Subsystemsº on page 18.

B.1 The IBM Software Migration Project Office (SMPO)

The SMPO is part of IBM′s North America Software Group and has been in business since 1993 providing solutions that help solve customers′ business problems. We do that by helping companies, like yours, migrate to the industry′ s leading systems management and database: DB2 and IBM/Tivoli products.

Many of our customers have made substantial investments in platforms which no longer support their growing business requirements. They have turned to us for help because the SMPO has the experience, the skills and the tools to assist them in executing a successful migration project.

IBM/Tivoli product offerings include a full suite of S/390 system and network management products for: system automation, enterprise job scheduling, security management, storage management, performance management and report management. These products and service offerings can provide alternatives to ISV products.

If you have any questions or need more information about the SMPO, feel free to navigate about our home page, or you can contact any one of our IBM/Tivoli Migration Team or Database Team personnel. The SMPO home page can be found at:

539 OS/390 specifications

IBM OS/390, a versatile operating system, was a cornerstone in enterprise environments and played a pivotal role in mainframe computing. Released in the mid-1990s, OS/390 combined the strengths of IBM's MVS (Multiple Virtual Storage) with new features and enhancements, targeting scalability, reliability, and performance in demanding business applications.

One of the key features of OS/390 was its robust support for multiple users and processes. The system allowed thousands of concurrent users to access applications and data, ensuring high availability and minimizing downtime—a critical requirement for many large organizations. This scalability was supported through various enhancements in memory management and processor scheduling, enabling optimal resource allocation across diverse workloads.

OS/390 was known for its superior workload management capabilities. The Workload Manager (WLM) component allowed administrators to define service policies, specifying how system resources would be allocated according to the priority of tasks. This ensured that critical business processes received the necessary resources while less critical tasks were managed more flexibly.

Another significant characteristic of OS/390 was its commitment to security. The operating system provided comprehensive security features, including user authentication, data encryption, and auditing capabilities. This focus on security was vital for organizations handling sensitive data, ensuring compliance with regulations and safeguarding against unauthorized access.

OS/390 also supported advanced technologies that facilitated integration and development. The system included features like the IBM CICS (Customer Information Control System) for transaction processing and IMS (Information Management System) for database management. These technologies allowed organizations to build robust, high-performance applications tailored to specific business needs.

The ease of network integration was another strength of OS/390. With the advent of the Internet and global connectivity, OS/390 systems could easily interface with various network protocols, enabling businesses to operate in a connected world. This inclusion paved the way for many organizations to expand their capabilities and offer new services, driving digital transformation.

In conclusion, IBM OS/390 represented a significant advancement in mainframe technology, combining scalability, security, and robust workload management. Its rich feature set and support for critical enterprise applications solidified its role as a vital component of many organizations' IT infrastructures, ensuring they could meet their operational challenges head-on while supporting future growth. As technology continues to evolve, the legacy of OS/390 remains influential in the realm of computing.
