Attachmate Verastream™ Bridge Integrator Overview

Verastream Bridge Integrator provides a mainframe-resident data engine that operates within IBM's CICS Transaction Server for z/OS version 3, release 1 (CICS TS 3.1) or higher. Your Java or Windows applications can communicate with CICS applications on an IBM host system to provide input to and retrieve data from CICS applications. The Bridge Integrator uses the CICS Web interface as the communications infrastructure using standard communications protocols such as HTTP and provides client classes in Java and .NET.

A choice of easy-to-use APIs quickly enable created applications to leverage the data, business logic, security, and integrity of existing CICS 3270 applications without the need for modification of those existing applications. This approach facilitates session connection, HLLAPI like processing, and symbolic BMS map field name processing of CICS 3270 screen applications and session cleanup. Further, since this approach shifts most of the processing to the mainframe through its host data engine, it delivers a new dimension in performance and scalability.

The Verastream Bridge Integrator Approach

The Verastream Bridge Integrator host data engine communicates with external requestors via a set of simple request/response packets enveloped within an HTTP packet design that communicate over TCP/IP with CICS Web Support, thus facilitating deployment to the Internet. These simple request/response packets are easily created by the simple API provided by the requestors. The requestors are thin servers that package and send API requests to the host data engine for processing. They also receive API package responses from the host data engine and deliver the results to the caller. Since customers may have varied platforms and architecture in their enterprise, the requestors come in Microsoft .NET and Java application platforms.
