JES DataGateway

JES DataGateway is designed to transmit JES2 and JES3 output from z/OS environments to non-mainframe servers using TCP/IP. It operates as a JES Functional Subsystem (FSS), integrating directly with the z/OS spooling system. The architecture comprises several key components: * **FSS Interface Module:** This module provides the interface between JES and JES DataGateway, capturing spool data and managing the communication with JES.

* **TCP/IP Communication Module:** This module handles the network communication, establishing TCP/IP connections with target servers and transmitting data. * **Data Transformation Module:** This module converts data formats as needed, ensuring compatibility between the z/OS environment and the target systems. Communication between these components is primarily through internal z/OS interfaces and TCP/IP sockets.

Configuration is managed through the FSS parmlib member, which defines TCP/IP settings, target server addresses, data transformation options, and security configurations. Security is integrated with z/OS security using RACF, and data transmission can be encrypted using TLS. The system leverages the z/OS system log (SYSLOG) for monitoring and logging.

Competing products offer similar functionality, but JES DataGateway is distinguished by its tight integration with z/OS security and its focus on performance within the z/OS environment.
