redhat enterprise linux 4 U 4<br />
two servers, each has 4GB RAM, shared storage, cluster oracle 10g rac database<br />
when I look at top command output and sums up all the oracle processes RAM usage (i.e. the RES top field) the result is more then the actual physical RAM<br />
this phenomena is on both servers<br />
how can it be axplained ? how can I monitor the real RAM usage of oracle processes ?<br />

top output total sum of oracle processes RAM usage is more than actual physical RAM

Oracle is an object-relational database management system. It supports a large number of languages and application development frameworks. Its primary languages are SQL, PL/SQL and Java, but it also includes support for C and C++. Oracle also has its own enterprise modules and application server software.

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).

Enterprise software, also known as enterprise application software (EAS), is computer software used to satisfy the needs of an organization, including businesses, schools, interest-based user groups, clubs, charities, or governments. Services provided by enterprise software are typically business-oriented tools such as online shopping and online payment processing, interactive product catalogue, automated billing systems, security, enterprise content management, IT service management, customer relationship management (CRM), enterprise resource planning (ERP), business intelligence (BI), project management, human resource management (HR), manufacturing and supply chain management, enterprise application integration (EAI), and enterprise forms automation. Enterprise software is often available as a suite of customizable programs that require specialist capabilities.
