Oracle Delivers Unique Value with Oracle Solaris: IDC White Paper [29784]
IDC Takes a Second Look at Oracle Solaris and Customer Attitude

In his comments on the revised IDC white paper "Oracle Delivers Unique Value with Oracle Solaris" Larry Wake remarks on its highlighting of how Oracle Solaris 11 is optimized for cloud computing, with unique virtualization, scaling, and provisioning capabilities, evidence, Wake notes, of Oracle's increased investment in Solaris since the Sun acquisition. White paper co-authors Gary Chen and Al Gillen include a case study based on the experience of Synodex, a medical records processing company that adopted Solaris 11 early. The white paper also notes a revitalized level of customer confidence in Oracle Solaris since 2010 vis-a-vis competitive major Unix solutions.

How to Configure a Failover Guest Domain in an Oracle Solaris Cluster [29690]
Oracle VM Server Provides Protection to Guest Domains Against Outages, Planned and Unplanned

Venkat Chennuru posts at length in an article that provides a step-by-step example of how to deploy an Oracle VM Server for SPARC guest domain in a highly available failover setup with a two-node Oracle Solaris Cluster 4.1 with a global file system on Oracle Solaris 11.1. The post also explains how to verify that the cluster is behaving correctly by switching over the failover guest domain from the primary node to the secondary node and back. Chennuru writes that the automated failover of a guest domain through restart on an alternate cluster node enables the protection of guest domains from planned and unplanned downtime.

How to Set Up a Hadoop Cluster Using Oracle Solaris Zones [29495]
OTN Article by Orgad Kimchi

This "article"] starts with a brief overview of Hadoop and follows with an example of setting up a Hadoop cluster with a NameNode, a secondary NameNode, and three DataNodes using Oracle Solaris Zones.

The following are benefits of using Oracle Solaris Zones for a Hadoop cluster:

  • Fast provision of new cluster members using the zone cloning feature
  • Very high network throughput between the zones for data node replication
  • Optimized disk I/O utilization for better I/O performance with ZFS built-in compression
  • Secure data at rest using ZFS encryption

Improvements in Image Packaging System for Oracle Solaris 11 a Welcome Change [29487]
Tightly Integrated, Single-tier Packaging/ Patching Architecture Eases Administrative Tasks

The Image Packaging System (IPS) for Oracle Solaris 11 is a single tier packaging architecture that replaces the previous SVR4-based dual tier packaging and patching architecture. Gerry Haskins sees it as a stellar element of the OS, leveraging ZFS Root (/), Boot Environments, SMF, Zones, and other Solaris technologies. Monthly consolidated bug fix Support Repository Updates (SRUs) now provide a regular predictable cadence of bug fix release baselines, greatly simplifying patch management. In his overview of the IPS Haskins identifies a number of the more common Solaris 11 / IPS issues that he, as a novice user, has encountered in since the release.

A Procedure for Migrating Zones on Shared Storage [29380]
Jeff Victor Advises Against Use in Production Environments

Zones on Shared Storage (ZOSS) enables users to store Oracle Solaris Zones on shared storage, Jeff Victor posts, so that users can perform quick and easy migration of a zone from one system to another. He offers the caution that the ability to use ZOSS to store a zone on a local disk is very useful for a lab environment, but not so useful for production, advising his readers not to regularly move disk drives among computers. Victor presents the nine steps in his migration procedure and includes the commands and outputs for each of them.
