'Best Practices for Deploying Oracle Solaris Zones with Oracle Database 11g on SPARC SuperCluster [30153]
Oracle White Paper
Giri Mandalika summarizes the Oracle white paper "Best Practices for Deploying Oracle Solaris Zones with Oracle Database 11g on SPARC SuperCluster," explaining that SuperCluster users have the choice of running their databases in logical domains dedicated to running Oracle Database 11g R2.
With exclusive access to Exadata Storage Servers, those domains are called "Database" domains. Users can create and use all logical domains as "database domains" or "application domains" or a mix of those, Mandalika writes. The paper talks only about database domains and their creation, configuration and use within each database domain for fine grained control over multiple databases in a SuperCluster environment.

White Paper: Implementing Root Domains with Oracle VM Server for SPARC [29976]
Introduces Root Domain Model as One of Several Architectures Supported by Oracle VM Server for SPARC
"Implementing Root Domains with Oracle VM Server for SPARC," a new Oracle white paper by Mikel Manitius, Michael Ramchand, and Jeff Savit, describes how to use Oracle VM Server for SPARC root domains (domains that are assigned a PCIe bus) along with Solaris zones for maximum performance and a high degree of flexibility. This combination can be used to provide bare-metal performance and eliminate dependencies between domains, and can be a useful alternative to deployments based on service domains and virtual I/O, co-author Savit posts. The paper introduces the root domain model as one of several architectures Oracle VM Server for SPARC product supports.

Running Solaris 11 as a Control Domain on a T2000 [28013]
Installing Logical Domains 1.2 Solves the Problem
As increasing numbers of users running older T1-processor-based systems like T1000 and T2000 upgrade to Solaris 11, there are few problems since Solaris 11 runs on any T-series or M-series SPARC server. One case presents an exception, however: running Solaris 11 in a control domain on a T1000 or T2000 hosting logical domains. Jeff Savit addresses this complication in his post that, in fact, proves Solaris 11 can be installed on T2000 servers and used as a control domain by removing the preinstalled Oracle VM Server for 2.2 and installing Logical Domains 1.2 - the last version of LDoms to support T1-processor systems.

SPARC T4-4 Processor:: Foundation of Oracle SPARC Supercluster [25043]
Integrates Solaris on SPARC, Exadata, Exalogic
Oracle has produced a true SPARC Engineered System that integrates Solaris on SPARC, Exadata and Exalogic. And this new system is the Oracle SPARC Supercluster, which is built on the new T4 chip and its new architecture, which has resulted in the SPARC T4-4 Server as the the top of the line 5RU model. SPARC Supercluster also includes the integration of Infiniband and the flexibility of Logical Domains (LDoms) as well as a ZFS Storage Appliance to support the Exalogic clustering storage needs, plus Exadata Cells.]
