PC/Transfer Modernization Guide

PC/Transfer facilitates file transfer between PC systems and z/OS or zVSE/VSEn environments. It supports various file types, including BIM-EDIT members, VSE Librarian members, VSAM datasets, CICS transient data, temporary storage, and ICCF members.

PC/Transfer supports both LU2 (3270 emulation) and TCP/IP connections for communication between the mainframe and the PC. The choice depends on the network infrastructure and security requirements.

Transfers can be initiated either from the PC or from the host system. Host-initiated transfers can be performed via batch jobs or CICS applications, providing flexibility in how file transfers are managed.

The exact command syntax depends on the transfer method (PC-initiated or host-initiated). Configuration files are used to define transfer parameters, such as file names, transfer types, and connection details. These files are typically specific to either the PC or the host environment.

PC/Transfer uses protocols such as LU2 (3270) or TCP/IP for communication. The choice of protocol affects the configuration and network requirements. LU2 typically requires 3270 emulation software, while TCP/IP requires a configured network connection.

The main system components include the PC client software, the host server component (running under CICS or Entree in VSE), and the communication link (LU2 or TCP/IP). These components work together to facilitate the transfer of files between the PC and the mainframe.

PC/Transfer enables efficient file transfer between PC and mainframe environments, which can streamline development, testing, and production processes. By supporting various file types and transfer methods, it enhances data accessibility and workflow efficiency.

By facilitating seamless data exchange, PC/Transfer can reduce manual data handling and potential errors. This leads to improved data integrity and faster turnaround times for critical business processes.

PC/Transfer leverages the security features of the underlying communication protocols (LU2 or TCP/IP) and the host environment (CICS or Entree). Specific authentication methods and access control models depend on the configuration of these environments.

Audit and logging capabilities depend on the host environment's configuration. CICS and Entree provide logging facilities that can be used to track file transfer activities and potential security events.

Administrative interfaces are available through the PC client software and the host environment (CICS or Entree). User management is typically handled within the host environment's security system.

Monitoring and logging capabilities depend on the host environment. CICS and Entree provide facilities for monitoring system activity and logging events, which can be used to track file transfers and diagnose issues.
