TIBCO Substation ES™ Concepts

Software Release 2.10

May 2016

  • Important Information
  • TIBCO Documentation and Support Services
  • Introduction
    TIBCO Substation ES™ subscribes to and publishes data to TIBCO applications and transaction processing systems, such as Customer Information Control System (CICS) and Information Management System (IMS), which run in the z/OS operating-system environment.
  • Architecture
    Substation ES is a Multiple Virtual Storage (MVS) application that runs in a single region.
  • Components
    Substation ES contains functional areas or layers and each is responsible for a given set of tasks and services.
  • Substation ES Messaging Agents
    When TIBCO applications issue requests to publish/subscribe to messages, the requests are processed by Substation ES through Message Receipt Agent and Message Delivery Agent. Those agents receive and deliver messages asynchronously.
  • Message Flow
    Substation ES accepts Rendezvous or Enterprise Message Service messages that originate from applications anywhere on the network. Conversely, Substation ES also accepts messages or events generated by transactions that are running within the CICS or IMS regions on z/OS.
  • Service Levels
    Substation ES supports different service levels for different messaging applications.
  • CICS Interface
    This section describes the CICS Interface used by Substation ES to pass data between TIBCO messaging applications and CICS applications in the z/OS environment.
  • IMS Interface
    Substation ES IMS Interface connects TIBCO messaging applications and IMS applications in the z/OS environment.
  • RED (XCF) Interface
    Substation ES RED Interface enables external applications to communicate (publish, request, or reply) with z/OS programs and transactions that are located in the batch, CICS, IMS BMP, IMS MPP or TSO regions.
  • Advanced Deployments
    With advanced deployment, you can deploy Substation ES to use the fault tolerance and load balancing features, deploy Substation ES in a z/OS Sysplex environment, and configure Substation ES to interact with CICS in various ways.
