IBM Z Program Development Tool

The architecture of the IBM Z Program Development Tool comprises several key components. The emulator core is the central processing unit (CPU) emulator, responsible for interpreting and executing mainframe instructions. The virtual device manager simulates hardware devices such as disks, tapes, and network interfaces.

The configuration manager handles the setup and management of the emulated environment, including defining virtual hardware and software configurations. Communication between components occurs through internal interfaces and shared memory. The tool does not use any specific databases or storage mechanisms beyond the host file system for configuration files and log files.

Network requirements include TCP/IP for communication between the emulated mainframe and external networks. The tool uses a command-line interface (CLI) for administration, providing commands to start and stop the emulator, configure virtual devices, and manage user access. The configuration files are used to define the emulated hardware and software environment.

The tool provides logging capabilities for monitoring and auditing purposes.
