A.3 Who will Provide the Training?

Hiring a skilled MVS person for the migration, whether temporary or permanent, helps with the skill level of that one person. Don′t assume that the person is a skilled educator or will have time to teach a curriculum to other team members in his/her spare time. It is likely that this person will have a list of responsibilities that may not include being a trainer and may not know VSE at all.

Benefits of on-site training

∙

∙

Curricula can be customized to suit your specific needs

Blocks of training (for example, one week) can be tailored to deliver the training when it is needed for the migration

IBM Education and Training (E&T) can help you with your training challenge by providing customized training. E&T specializes in presenting a common basic curriculum to a mixed audience of operators, applications programmers and system programmers (OS/390 basics, how to use ISPF, JCL basics) and then splitting each audience to learn those topics specific to their job performance.

A.4 Where will the Training Take Place?

There are a number of items to consider regarding where training takes place. Among them are cost, how the time the class is offered fits with the project needs and the availability of the students.

One consideration is that if you choose to bring in a trainer for a particular class, consider delivering the class somewhere other than the normal work location such as across town at a hotel. This can provide just enough distance to keep the students from being drawn into daily problems at the office.

Having training delivered on site versus go away schools provides significant advantage in class scheduling. The on-site class can be scheduled for the time the skill is ready to be used. For go away classes you are normally limited to the specific times the class is offered.

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.
