How does VSE-ON-MVS accelerate the migration process?

By allowing organizations to reuse existing assembler code, VSE-ON-MVS accelerates the migration process. This faster migration enables organizations to modernize their infrastructure more quickly, taking advantage of the benefits of z/OS.

How does VSE-ON-MVS reduce the risks associated with migration?

VSE-ON-MVS helps organizations avoid the need to rewrite large portions of their existing applications. This reduces the risk of introducing errors and ensures that the functionality of the original applications is preserved during the migration.

How does VSE-ON-MVS support business continuity?

VSE-ON-MVS allows organizations to maintain their existing applications while transitioning to a modern platform. This ensures business continuity and minimizes disruption during the migration process.

What authentication methods are supported by VSE-ON-MVS?

VSE-ON-MVS supports standard z/OS security features. It integrates with existing security infrastructure, such as RACF or equivalent security managers, to control access to resources. The product itself does not introduce its own authentication mechanisms.

What access control model is used by VSE-ON-MVS?

Access control is managed through the z/OS security infrastructure. This typically involves the use of access control lists (ACLs) and role-based access control (RBAC) to define and enforce permissions. The product leverages the existing security model of the z/OS environment.

What encryption methods are used by VSE-ON-MVS?

VSE-ON-MVS does not provide its own encryption capabilities. It relies on the encryption features available within the z/OS environment. Data encryption is handled by the underlying z/OS system, ensuring data security.

What audit and logging capabilities are available in VSE-ON-MVS?

VSE-ON-MVS integrates with the z/OS auditing and logging mechanisms. All actions performed by the product are logged through the standard z/OS logging facilities. This allows for comprehensive auditing of system activity.

What administrative interfaces are available for VSE-ON-MVS?

Administrative tasks are performed through standard z/OS interfaces, such as the ISPF panels or the z/OS console. There is no dedicated GUI or web console for VSE-ON-MVS. Configuration is managed through z/OS system parameters and datasets.

How is user management handled in VSE-ON-MVS?

User management is handled through the z/OS security system, such as RACF. User access and permissions are managed using the standard z/OS security tools. VSE-ON-MVS does not have its own user management system.

What are the main configuration parameters for VSE-ON-MVS?

The main configuration parameters are related to the re-assembly process and the emulation libraries. These parameters are typically set in JCL or in configuration datasets. Detailed documentation provides guidance on these settings.

What monitoring and logging capabilities are available?

VSE-ON-MVS integrates with the z/OS monitoring and logging facilities. System activity and performance metrics can be monitored using standard z/OS tools. Detailed logs are generated to assist with troubleshooting and performance analysis.

Product Overview

The architecture of VSE-ON-MVS centers around the re-assembly of z/VSE assembler code for execution on z/OS. The main components include the re-assembler, emulation libraries, and a set of utilities. The re-assembler is the core component, translating VSE assembler source code into an object code format compatible with z/OS.

This process involves parsing the source code, converting instructions, and handling differences in system calls and data structures. The emulation libraries provide the necessary system service interfaces, allowing the re-assembled code to interact with the z/OS operating system. These libraries emulate VSE system services, such as file I/O, memory management, and task scheduling.

Utilities assist with tasks such as data conversion, job control, and debugging. The product uses standard z/OS file systems for storage, primarily datasets. Data is accessed using standard z/OS I/O methods.

Network communication, if required, uses standard protocols such as TCP/IP. The product integrates with the z/OS security infrastructure, using ACLs and RBAC. Administrative tasks are performed through standard z/OS interfaces, such as ISPF panels or the z/OS console.

Configuration parameters are set in JCL or configuration datasets. The product integrates with the z/OS monitoring and logging facilities.
