Anticipating IBM Corp’s preview of its high-performance parallel mainframe search system due today, NCR Corp yesterday enhanced its parallel NCR 3600 and DBC/1012 systems. There are enhancements to the Ynet high-speed interconnect between the processors, Pentium upgrades for the Application Processors and 80486 DX2 upgrades for the Access Module Processors for both machines via board swaps. The Teradata Database System 1.5 adds a Performance Monitor, Two-Phase Commit, Join Optimization, FastExport, Teradata Manager 2.0, use of both high speed Ynet intelligent interconnects in a single operation, and enhanced Password Security options. Oracle Corp is also now offering the beta test version of Oracle7 7.1 with Parallel Query Option. The alpha release of Sybase Navigation Server is also available on the NCR 3600: NCR says it conceived, developed, and owns the base technology for the Navigation Server and chose Sybase Inc as its joint development partner. For co-existence in the IBM Corp mainframe world, there is a new Multi-protocol Connectivity Manager to provide high-speed local network and Async communications via an SCSI connect, which saves Micro Channel slots on the 3600 AP. Up to four IBM and Unisys Corp channel connections can now be supported per 3600 AP. The new Pentium Application Processor is expected to roughly double system performance, for an additional 20% cost. For the 3600 Access Module Processor, the DX2 processor will deliver up to a 73% performance improvement at the price of the current 33MHz 80486 processor NCR said.
