INFORMIX-OnLine XPS to be ported to Open Parallel Unisys Server (OPUS).

SAN JOSE, Calif.--(BUSINESS WIRE)--July 18, 1995--Unisys Corp. and Informix Software Inc. Tuesday announced that Informix will port the INFORMIX-OnLine Extended Parallel Server(TM) (OnLine XPS) relational database management system (RDBMS) to the Open Parallel Unisys Server (OPUS).

The OnLine XPS RDBMS is scheduled for general availability in 1996.

The port paves the way for one of the industry's largest user segments to take advantage of the dramatic performance improvements made possible by parallel processing technology.

It joins Informix's Dynamic Scalable Architecture (DSA), the company's industry-leading Parallel database technology and the core technology for OnLine XPS, with UNIX SVR4/MK, the OPUS parallel implementation of the industry's most commonly accepted, standard operating software.

This means that UNIX solutions incorporating Informix database technology can be ported directly -- without the time and expense penalties of rewriting solutions -- to a parallel architecture for the first time.

"The combination of OnLine XPS' shared-nothing architecture with OPUS' scalable processors will provide customers with the potential for tremendous availability and scalability for online transaction processing, decision support applications, and data warehousing environments," said Phil White, president and CEO of Informix Software Inc.

"Our approach in providing a solution that is appropriate for each multiprocessor architecture, whether it be SMP, or massively parallel, will ensure that our customers can evolve their architectures and give them the flexibility to choose the best solution for their computing needs."

"The availability of OnLine XPS on OPUS is an especially important milestone in fulfilling our commitment to OPUS database independence, a central requirement for the widespread adoption of parallel processing in an open computing environment," said Alan Lutz, president of Unisys Computer Systems Group.

"Along with steps such as the licensing of the OPUS UNIX operating system to any platform vendor and the reselling of the OPUS platform by Intel and other third party vendors, it is one of a series of initiatives we are taking to drive the acceptance of OPUS as the industry standard in commercial parallel processing."

OPUS and OnLine XPS: Complementary Strengths

OnLine XPS database architecture will enhance users' ability to benefit from several of the breakthrough features that differentiate OPUS in the commercial parallel processing marketplace: -0-

o  Scalability -- OnLine XPS' ability to scale from small to
   very-large-scale data warehousing solutions complements the OPUS
   capability to grow in processing power, interconnect bandwidth,
   I/O bandwidth and mass storage.  OPUS users can scale from eight
   to 128 Intel microprocessors, and can upgrade from Intel Pentium
   to P6, with no changes in the underlying interconnect hardware.

o  Shared nothing architecture -- OnLine XPS and OPUS both
   support separate memory and I/O for each processor.  This
   eliminates memory-to-processor bottlenecks that can occur in
   conventional, shared-resource multiprocessor systems operating on
   larger-scale computing tasks.

o  Single-System Image -- OPUS eliminates the need for users,
   software developers and system administrators to know which
   processing node is operating on data, providing centralized
   control through a graphical console.  The latest release of
   OnLine XPS includes systems management tools based on the Tivoli
   Management Environment (TME) enabling the administration of
   multiple databases through a single-system view.-0- Informix Corp.
