Installing Oracle RAC 11gR2 on the Oracle Solaris
11 OS by Using Oracle VM Server for SPARC
This paper describes how to install Oracle Real Application Clusters (RAC) on an Oracle Solaris 11 server by
using the Oracle VM Server for SPARC software.
Introduction
Oracle Real Application Clusters (RAC) is a cluster database with a shared cache architecture that
overcomes the limitations of traditional “shared-nothing” and “shared-disk” approaches to provide
highly scalable and available database solutions for all your business applications.
The shared-nothing approach assumes that each node in a cluster has sole ownership of the data
on that node. The shared-disk approach, also known as the “shared-everything” approach, assumes
that one array of disks holds all of the data in that database. Each server or node in the cluster acts
on that single collection of data in real time. The “shared-cache” approach is based on the shared-
disk architecture. The overhead of sharing data by means of the disk, which is the slowest
component in the system, in introduces a significant performance penalty. The shared-cache
approach uses a high-speed cache to share information between nodes, which is much faster than
sharing by means of the disk.
Oracle VM Server for SPARC (previously called Sun Logical Domains) is Oracle's server
virtualization and partitioning technology for Oracle's SPARC T-Series servers. Oracle VM Server
for SPARC leverages the SPARC hypervisor to subdivide the resources (CPU, memory, I/O, and
storage) of each supported platform by creating partitions called logical domains (or virtual
machines). These logical domains can take advantage of the massive thread scale that is offered by
SPARC T-Series servers and the Oracle Solaris 11 operating system.
Oracle RAC is always deployed in to a virtualized environment in the following ways:
Development environment. Deploy multiple Oracle RAC nodes on the same physical server
to reduce hardware costs.
Production environment. Place each Oracle RAC node on a separate physical server for
increased availability
This paper describes how to deploy four Oracle RAC 11g Release 2 (11gR2) nodes in a guest
domain on separate SPARC T-Series servers to simulate a production environment. Both the
control domains and the guest domains are installed with the Oracle Solaris 11 OS.
This paper covers the following topics:
Configuring a logical domain on a SPARC T-Series System that runs the Oracle Solaris 11 OS
Configuring the Oracle RAC 11g R2 software in a logical domain
