OpenVMS OS, Oracle Software Break Performance Barrier

Recent performance tests of Oracle Rdb Version 7.1.2 and Hewlett-
Packard
OpenVMS Versoin 7.3-2 running on an HP AlphaServer GS1280 system 
have
demonstrated breakthrough transaction performance for a single
32-processor symmetric multiprocessing (SMP) machine configured with 
256
gigabytes of main memory, an HP spokesperson said in a press release.

The AlphaServer system, together with Oracle Rdb software, achieved
sustained throughput of 1,010,160 database transactions per minute. 
In
this test, five tables with a total of one billion rows were reated and
their contents were mapped in main memory using Oracle Rdb's Row 
Cache
feature, the HP spokesperson said, adding that the test, designed to
explore the limits of the Row Cache feature, was not highly optimized
for performance. But, he continued, additional performance tuning is
likely to result in even higher transaction rates.

"This new implementation of Row Cache, first available in Oracle Rdb
Version 7.1.2, allows customers to fully utilize all the physical memory
present in the  largest AlphaServer systems for caching databases that
retain complete transaction integrity and full recovery from process,
disk, or system failure," the HP spokesperson said in the release. The
OpenVMS Version 7.3-2 operating system provides a number of key 
features
for improved scheduling and resource utilization that enhance
scalability on systems with many processors. These features were fully
utilized in the test, the release added.
