The GCOS 8 - Open Systems Interoperability offer (" Interoperability 8 ") has evolved from transaction processing applications cooperation (mainly TP8 - Tuxedo applications' cooperation) towards e-business solutions integration with GCOS 8 environment.

Since more than six years the integration of GCOS 8 applications with solutions designed for open systems has been made available according to the main technological frameworks evolution.

Two mainstream technologies have been pervasively implemented successively in GCOS 8 environment :
 - Client/Server architecture and distributed transactional processing
 - Internet and the Web

For those two families of technologies, GCOS 8 interoperability solutions have been designed and delivered in the perspective of fulfiling the major concern of GCOS 8 regarding the robustness of the transaction processing application aka " TP8 production " 7/7-24/24.

GCOS Interoperablity & e-Business evolution

The ambition of Application Servers is to become the portal of Information Systems, they will have to capitalize on investments in re-usable components the code of which is either new or to be harvested in existing systems.

GCOS 8 customers have to cope with a following main issues :

- as for all large IT shops (design, programming, production) how is mastered the paradigm shift from a procedural world towards a component one.
- will the E-infrastructure leverage in seamless and secure way existing corporate Data and will it take benefit of XA8, this new enabling "cyber-gateway" of secure transactional e-solutions.

The multi-tier architecture pervasively endorsed by corporate IT organizations relies on component based Application Servers front-ending the so-called Enterprise Information Systems (EIS) that comprise database servers, ERP or mainframe applications. This cutting edge Information Systems architecture is described hereunder:
