Oracle on LINUX
Platforms
LINUX combines the ease of use and cost-effectiveness of Intel
hardware platforms with the performance, reliability and
availability of enterprise-class UNIX servers. If the application
requires more processing power, CPUs, memory and disk can be
purchased without making a major impact on the business unit’s
operating budget. LINUX is designed to be user-friendly and easy to
install. LINUX can be installed on a home PC as well as a network
server for a fraction of the cost of competing software packages.
Compared to their Windows and UNIX
counterparts, the majority of LINUX vendors have only recently begun
to expend resources on providing highly available architectures to
consumers desiring fault tolerant systems for mission-critical
applications. The reasons for this lack of focus are:
-
The LINUX operating system is relatively new
and has only become recently popular with corporate consumers.
Historically, large corporations have not considered LINUX as a
viable corporate operating system. One can only assume that most
corporations felt that anything that was free wasn’t a viable
product. Only when Red Hat and other competing vendors began to
formalize and “corporatize” their LINUX offerings did corporate
consumers begin to consider LINUX as an alternative to Windows and
UNIX.
-
Consumer perception (or misconception) that the
UNIX operating systems are inherently more reliable than their LINUX
counterparts resulting in a lack of consumer demand for highly
available LINUX servers.
-
Market analysis showing that product cost and
not high availability being the primary reason consumers choose
LINUX environments.
