Oracle Data Provider for .NET (ODP.NET) – .NET data provider designed exclusively by and for Oracle for opmal data
access from .NET to Oracle 9i Database and Oracle Database 10g. Can be used from any .NET language, including C# and Visual Basic
.NET.
Microso Windows Server oers a powerful plaorm for deploying an Oracle database, parcularly an Oracle RAC database.
Windows Server Edions oer all of the scalability and exibility that you need for developing a robust producon database. The rst
step towards building your own RAC database is choosing the right Windows Server Edion.
One of the key dierences between Microso Windows Server Edions is their support for 32-bit or 64-bit architectures. Almost all
exisng Windows databases are currently deployed on 32-bit architectures. Oracle supports Windows 2000 Server (with Service Pack
1 or higher) and Windows Server 2003 in all Edions with the 32-bit versions of Oracle9i and10g. Choosing a 32-bit Windows Sever
Edion can ease the migraon from legacy databases and applicaons.
To make the transion easier, Intel is oering the EM64T architecture to bridge the 32- bit and 64-bit applicaon worlds. The Intel
EM64T processor supports both 32-bit and 64-bit versions of Microso Windows Server 2003. In addion, Dell is oering the
PowerEdge 1850, 2850, and 6850 rack-ready servers to take advantage of the Intel EM64T architecture. The PowerEdge 6850 server
is the “agship” of the Intel EM64Tbased line, oering 4-way scalability and a number of performance improvements over previous
servers. The combinaon of Intel EM64T processors, Microso Windows Server 2003, and the Dell PowerEdge 6850 Server will make
an ideal plaorm for transioning to 64-bit databases.
Choosing a 64-bit Windows Server Edion can be benecial for large databases or data warehouses that have substanal memory
requirements. 64-bit versions of Windows Server navely support large Oracle SGAs without the need for memory extension
techniques. There is no performance penalty for databases with SGAs larger than 3 GB. Many companies are already choosing 64-bit
versions of Microso Windows for deploying new mission-crical databases. Microso currently oers Windows Server 2003
Enterprise Edion and Datacenter edion for systems with 64-bit Intel Itanium 2 processors. In the near future, Microso will oer
64-bit versions for all WindowsServer 2003 Edions for use with the new Intel EM64T processor. One of the advantages of the Intel
EM64T plaorm is that it will allow a mixture of 32-bit applicaons and 64-bit applicaons to run simultaneously under the
upcoming 64-bit version of Microso Windows Server 2003. The Dell PowerEdge 6850 server is designed for opmal performance
with the 64-bit EM64T version of Microso Windows Server 2003.
Please note that this paper will only cover the installaon process for the 32-bit version of Windows. If you plan to install a 64-bit ver-
sion of Oracle10g, you can use this guide, but be sure to download the 64-bit version of Oracle10g Database (available soon for the
EM64T 64-bit plaorm).
Preparing Windows Server for Oracle Installaon
At rst glance, installing the Windows OS prior to deploying an Oracle database may seem to be a relavely simple task. Aer all,
most of us have some experience with installing Windows Operang Systems. It would seem to be well within our “comfort zone”.
