tier configuration detailed above, a PowerEdge 1950 is ideal for a stand-alone J2EE

server or one or more servers utilizing Web Cache as a front-end for a set of application

servers. In the Enterprise topology, PowerEdge 1950 servers are ideal for clustered J2EE

and Web Cache servers.

Dell PowerEdge 2950 servers are useful for a wide variety of OracleAS roles. These are

2U rack servers with two processor sockets and three expansion slots. These servers are

ideal for the middle or infrastructure tiers. They may also be used as Corporate Database

/ Metadata Repository servers for small-medium size databases.

Dell PowerEdge 6850 and PowerEdge 6950 servers are 4U rack servers, with four

processor sockets and seven expansion slots. This server class is typically used for large

corporate databases. In some cases, these servers can be used as a powerful middle tier

or infrastructure tier servers. However, it is generally preferred to use multiple

PowerEdge 2950 servers to “scale out” middle/infrastructure tiers to enable load

balancing and redundancy.

Linux OS Installation – Preparing the System for

Oracle Application Server

Installing the Linux Operating System to prepare for an OracleAS implementation need

not be a daunting task. The Linux OS installation process can be broken down to five

basic steps:

1. Meeting the minimum hardware requirements

2. Choose the correct OS version

3. Basic OS installation

4. Post-installation configuration

5. Configuration for the Metadata Repository

Minimum System Requirements

Before beginning the installation process, it is important to configure the hardware to

meet or exceed the minimum system requirements for Oracle Application Server.

Ideally, the requirements should be checked before the Linux Operating System is

installed, or even before the hardware is ordered from Dell. However, it is not

uncommon that an existing server is re-purposed, or the OS is installed before all of the

requirements are fully checked. For these reasons, it is useful to know how to confirm

that the requirements have been met by issuing commands from the Linux command line,

so relevant OS commands will be listed below.

The easiest requirement to meet is the requirement for processors. At minimum

OracleAS requires at least one 300 MHz processor. Dell recommends at least two

processors. In fact, all of the recommended Dell systems listed above support two

sockets (single core or dual core), with speeds at 1.6 GHz and above. To check processor

speeds in Linux, use the following command:

# cat /proc/cpuinfo | grep MHz
