Unisys Corp, an early development partner of Chorus Systemes SA, is contributing its single system image capabilities to Unix System Laboratories Inc’s planned microkernel architecture. The technology enables users and developers to view servers as if they were a single system, enabling applications to be distributed across the network seamlessly for high-performance transaction processing tasks. Unisys will also be contributing object management technology to enhance programming and distributed systems management. In particular it will develop electronic software distribution and installation applications and license them back to Unix Labs for inclusion in its Tivoli Systems Inc-based Distributed Manager framework. Price and ship dates for the applications will be announced next month.
