ICL Plc has quietly become one of the most frequently called-upon technology partners for Unix System Laboratories Inc, and in the latest partnership Unix Labs has retained ICL to supply it with the core Open Systems Interconnection transaction processing engine for incorporation into Unix Labs’ OSI Open Networking Platform product family. The International Standards Organisation is set to ratify the open systems transaction processing standard shortly. Unix Labs will be enhancing its Tuxedo System/T transaction processing manager to work with the enhanced Open Networking Platform, to create what is claimed will be the first completely standards-compliant transaction processing system, including Application Programming Interface and protocol conformance; ICL will in turn build the OSI TP product into its Tuxedo-based system for Unix, and its TPMS for VME mainframes.
