Installing Oracle RAC on Windows
Question: How do I install Oracle RAC on a Windows
Platform. I?m a beginner, and the documentation does not help and I want step
by step directions for installing and configuring RAC on my Windows PC.
Answer: For Windows-based RAC database
systems, both the Windows 2000 and Windows 2003 are supported. Windows 2003
refers to enterprise, data center and standard edition. Windows 2000 refers to
Advanced Server and Datacenter Edition. Note that the RAC clusterware is
supplied by Oracle.
Ordinarily, the data files, control files, and redo log
files need to reside on the unformatted raw devices on a Windows RAC platform.
However, with the Oracle9i Release 2 (220.127.116.11.0) there is the option of using
the cluster file system for setting up the shared storage volumes for the RAC
database. If Oracle9i Release 1 (18.104.22.168.0) is being installed, logical
partitions (otherwise known as RAW Partitions) for the shared disks must still
In a Windows environment, the raw devices are more commonly known as logical
drives that reside within extended partitions.
Installing Windows OCFS for RAC
The Oracle Cluster File System (OCFS) for Windows
OCFS is a shared file system specifically designed for Real Application
Clusters. It allows multiple nodes to share Oracle Home and databases on a
single SAN volume. All nodes in the cluster have concurrent ownership and access
to the shared disks.
For installing OCFS on Windows RAC, Oracle supports all
database files and installation of the Oracle software. It was designed for use
of an Oracle database, not a new general-purpose file system. The single shared
Oracle Home aids the install process by providing a consistent image of binaries
and metadata across the RAC cluster.
However, according to Oracle MOSC Note # 225550.1, the current version of
OCFS for RAC does not support access from mapped drives in the Windows
Getting help installing Windows RAC
Installing and configuring Oracle RAC is quite complex, and
many shops hire experienced Oracle
If you want to install Oracle RAC on Windows yourself, in
lieu of the Oracle RAC
training, I recommend the book "Oracle
10g RAC and Grid".
For installing RAC on a Windows PC, there is a whole book
dedicated to installing and configuring RAC on a PC by Edward Stoever.
If you are a neophyte in RAC, it's best to get the step-by-step directions from
the book "Personal
Oracle RAC Clusters: Create Oracle 10g Grid Computing at Home".
