McDonnell Douglas Information Systems Ltd, which wants to use AT&T Co’s Tuxedo transaction processing monitor on its new Series X multi-processors which are based upon Encore Computer Corp’s Motorola 88000 Encore 93 line, is currently in talks with database vendors Oracle Corp and Ingres Corp – which originally committed to the AT&T software – to make sure that they’ll carry on developing for Tuxedo despite the fact that NCR Corp’s Top End monitor has won out over Tuxedo following the planned harmonisation of AT&T and NCR’s product lines. Matt O’Malley, director of system products at McDonnell Douglas, said the firm wants to continue with Tuxedo because it believes that the AT&T offering has a two- to three-year lead over Top End. Series X employs a dual-bus architecture which comes from Encore’s Multimax computer line, to which McDonnell Douglas has added VME functionality. Encore has not included the dual-bus on its 93 Series because they are primarily aimed at the real-time market, said O’Malley. Applications running under McDonnell Douglas’ Reality/X version of Pick under Unix on its existing National Semiconductor Corp NS32532-based RX series – also from Encore will run on the Series X systems without re-compilation, the company claims, because Reality/X applications – the Pick variant is implemented as an application under Encore’s multi-threaded Umax Unixalike – generate pseudo-code via an interpreter, code that is reckoned to be processor-independent.
