Multiple processors in a single server machine increases the
machines power to serve more users or in other word all the
processors within one server machine work together based on the
technique called Parallel Operation. I bought a used PIII Xeon
Quad Server machine from eBay at a cost of $380. This machine
is having 4 PIII Xeon processors, three power supplies, three
hard disk (SCSI) drives which I have configured for mirroring. If
one hard disk fails, the server will still be up and running.

have full understanding of one Instance Oracle systems.
