Product Overview

TIBCO EMS Client for z/OS (MVS) is a software that makes applications running on IBM z/OS systems produce and consume messages that are transported via TIBCO EMS servers. TIBCO EMS client applications can use SSL for secure communications with TIBCO EMS servers using standard API calls.

Messages are structured data that one application sends to another. TIBCO EMS servers, running on platforms outside the traditional z/OS environment, act as intermediaries for messages and route them to recipients. This messaging flow is illustrated in the following figure:
An application participates in this messaging environment as follows:
  1. The application embeds TIBCO EMS API function calls to facilitate message communication.
  2. The TIBCO EMS Client for z/OS (MVS) establishes connections to a TIBCO EMS server by using standard TCP/IP.
  3. The application sends messages to or receives messages from the TIBCO EMS server by using destinations for message routing.
  4. Other TIBCO EMS clients exchange messages with the application via the TIBCO EMS server.

TIBCO EMS API function calls are coded by programmers and included in the application at compilation time. The product <USERHLQ>.LIBRARY data set contains the objects that are included during the pre-link step of a compilation. The program can also compile and bind an application by using the EMS-supplied DLL sidedeck.
