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

Orgad Kimchi is the article author.

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.

Report on the Status of the Solaris 11.1 FIPS 140-2 Evaluation Process [29268]
Darren Moffatt Advises the Outcome will be Some Time in Coming

Darren Moffatt posts an outline of the FIPS 140-2 evaluation process for Solaris 11.1. He notes that Solaris 11.1 has just recently been granted CAVP certificates by NIST, which is the first formal step in getting a FIPS 140-2 certification. He adds that it will be some months yet before the results of the CMVP (FIPS 140-2) evaluation will be available, however, because of the multiple certificates for each algorithm to cover the cases of SPARC and x86 both with and without hardware acceleration from the CPU. His post includes links to references pertaining to the several aspects of the evaluation process.

Upgrading an Oracle Solaris 11 Repository with 11.1 Packages [29269]
Two Options: pkgrecv or Downloading Repository Image File

It takes 12 steps in the procedure Rick Ramsey outlines to upgrade an Oracle Solaris 11 Repository with 11.1 Packages. His instructions assume users already have a local Oracle Solaris 11 11/11 IPS package repository that they want to update by adding Oracle Solaris 11.1 packages. He provides two options: using the pkgrecv command or downloading a repository image file and tailors the procedure to accommodate both. Reader Tim Foster registers a preference for using pkgrecv because, he writes, it requires much less work than downloading the repository and performing the necessary manual steps.
