XCOM Modernization Guide

XCOM is a file transfer solution that facilitates peer-to-peer data exchange between mainframe systems and other platforms like Windows, UNIX, and Apple. It supports both SNA and TCP/IP protocols for communication.

XCOM supports various platforms including z/OS, z/VM, and zVSE/VSEn for mainframe environments, as well as Windows, UNIX, and Apple operating systems.

XCOM was initially developed by Proginet in the late 1980s, later acquired by Spectrum Concepts, then Legent, CA, and finally Broadcom.

Common commands include TRANSFER to initiate file transfers, LIST to view transfer queues, and MODIFY to alter transfer parameters. Configuration is primarily managed through configuration files.

XCOM exposes APIs for integration, including options for REST and potentially native APIs depending on the specific platform. Communication protocols include SNA and TCP/IP.

Key components include the XCOM server, transfer engine, and communication modules. These components communicate via internal APIs and network protocols. Data is stored in files and databases, depending on the platform.

XCOM uses configuration files and platform-specific interfaces for configuration. User management is handled through the operating system's user management tools and XCOM's internal security settings.

XCOM enables secure and reliable file transfer, reducing the risk of data loss or corruption. It supports automation of file transfer processes, improving efficiency and reducing manual effort.

By automating file transfers and integrating with existing systems, XCOM helps reduce operational costs and improve overall productivity.

XCOM supports authentication methods such as LDAP, Kerberos, and X.509 certificates. It employs an access control model based on role-based access control (RBAC).

XCOM uses encryption protocols such as TLS/SSL to secure data in transit. Audit logging capabilities provide detailed records of file transfer activities.

Administrative interfaces include a command-line interface (CLI) and potentially a web-based console, depending on the platform. Monitoring capabilities include logging to system logs and dedicated monitoring tools.

Key configuration parameters include transfer parameters, security settings, and network configuration. XCOM provides logging capabilities for monitoring file transfer activities and troubleshooting issues.
