Tolerant Systems Inc, whose transaction processing and fault tolerant technology has already attracted Bull SA of France and RC Computer A/S of Denmark into technology exchange agreements, has set up a European subsidiary operation based in Slough, Berkshire with the main aim of interesting other European manufacturers in its skills. The move was prompted by increasing interest in Tolerant’s TX Unix implementation, which embeds transaction processing and fault-tolerant capabilities within the operating system: both RC Computer and Bull are porting the software to their own machines as a basis for systems development. Tolerant has also become involved in the X/Open Group’s efforts to establish standards for transaction processing, and has contributed to the forthcoming X/Open white paper on the subject. Allan Fleming-Hubertz, heading the three- strong team at Tolerant Systems Ltd, claims that TX already conforms to 10 of the 12 standard interfaces specified in the paper. The company expects to close two technology agreements worth $5m each, as well as $5m revenue from sales through distributors and resellers, in its first year in the UK. Main competition comes from Tandem Computers and Stratus Computer. Tolerant has recently signed a sole distributor agreement with Metrologie SA of Paris, aimed at the viewdata, telecommunications, and financial services markets in France. Other successes, as reported, include being chosen to provide hardware for a $176m administration project for the Korean Government.
