4. It is a best practice to use the Repository Creation Assistant to install the Oracle

Metadata Repository in an existing Oracle Database.

5. To achieve scalability for the Infrastructure/Data tier, it is a best practice to host

the Metadata Repository/Corporate Database on Oracle Real Application

Clusters. This configuration provides high availability and enhanced database

performance. Database servers that are commonly used include Dell PowerEdge

2950 servers for small and medium size databases, or PowerEdge

6850/PowerEdge 6950 servers for large databases.

6. To achieve load balancing across OracleAS Clusters and RAC clusters, load

balancing routers must be used. Software load balancers, such as Web Cache can

balance TCP/IP and http load, but cannot handle LDAP load balancing. For this

reason, dedicated hardware load balancers such as F5 Networks BIG-IP routers

are required.

7. Dell/EMC Clariion shared storage is required for Oracle RAC databases, but is

optional for middle tier servers.

8. For security purposes, a firewall between the outside world and middle tier

servers is strongly recommended. A firewall between middle tier components and

Infrastructure components is desirable for Enterprise deployments.

Summary

Application Servers that implement Java 2 Enterprise Edition standards have become one

of the leading method for deploying Enterprise applications.. All Application Servers

must interface with Corporate Databases. Oracle Application Server 10g has a distinct

advantage over other J2EE Application Servers, due to tight integration with Oracle

Enterprise Edition databases and Oracle Grid Control.

Dell PowerEdge Servers and Dell/EMC Clariion SAN storage provide a flexible and

reliable platform for deploying Oracle Application Server 10g. Dell PowerEdge Servers

offer the power that is necessary to drive processing intensive applications, and offer

attractive price/performance ratios All of the dual socket Dell PowerEdge servers are

appropriate for OracleAS implementations, with the choice of servers depending on the

deployment topology and the total load.

In this whitepaper, a “blueprint” was provided for a three-tier Oracle Application Server

10g deployment on the Red Hat Linux Operating System. Step-by-step installation

instructions were provided for the following components:

• Oracle Application Server Containers for J2EE (OC4J)

•

Oracle Application Server Web Cache

•

Oracle Identity Management (single sign-on, OID)

•

Oracle Forms Services

• Oracle Reports Services

• Oracle Portal

The options available for expanding to a multi-tier Enterprise deployment topology were

also discussed. Dell/Oracle Best Practices for implementing a scalable, highly available

middle tier were provided to guide Administrators in successfully implementing Oracle

Application Server 10g on Dell PowerEdge servers.
