Three times the amount of RAM is recommended. For systems with more than 1 GB of memory, the allocation can be reduced to twice the amount of RAM or less. One year of annual OS maintenance certified for the Oracle environment Enterprise-class support from Red Hat provides localized support via Red Hat service centers worldwide One year of enterprise server support, unlimited incidents covering installation, configuration, and advanced configuration. The Red Hat Linux Enterprise Edition includes Version 1.1.8 of IBM' s Java runtime and development environment.

Systems administrators can efficiently administer multiple machines from remote locations.
Systems administrators will also appreciate the ease with which they can provide the Oracle environment to all users on a Linux server. This mechanism allows custom changes to system environments that are maintained across operating system upgrades, reducing the long-term maintenance overhead of a Linux server. By maintaining a single database instance, system administration and maintenance requirements are also reduced. This enables use of the maximum RAM supported in Intel environments. This feature circumvents operating system intervention in data-centric processes, allowing Oracle direct control over its database without interference from the system kernel.
