Oracle RAC DB 11gR2 on Oracle VM Server for SPARC (LDoms)
A 'Cookbook' Approach to the Installation and Configuration

The blog post "Deploying Oracle RAC DB 11gR2 on LDoms Virtualization" is a "cookbook" approach to configuring and installing Oracle Real Application Cluster (RAC) Database on Solaris 10 and Logical Domains on Sun CMT servers (also using ZFS). He concludes that LDom is a good choice for RAC deployment for, among other reasons, it is a virtualized hosted environment; it permits easy reallocation/deallocation of system resources dynamically; it allows for optimized system utilization and space/utility consumption.

Oracle Solaris on the Oracle Exadata Database Machine
Oracle White Paper Examines Optimal Combination
Oracle Solaris, one of two operating system options for the Oracle Exadata Database Machine, delivers key datacenter advantages in mission-critical reliability, performance and scalability, and security for the Exadata systems. Oracle Solaris has been modified and tuned over 25 years of collaborative effort with Oracle Database engineers to run even the world's largest and most responsive databases. The Oracle white paper "Oracle Solaris on the Oracle Exadata Database Machine" provides a high-level overview of the Oracle Exadata Database Machine and describes as well the value the Oracle Solaris, optimized and integrated for utmost performance, brings to the Oracle Exadata offering.
Oracle Solaris Cluster 3.3 05/11 Update1 Patches
New Applications Qualified, New DR Options Featured

Along with his announcement of the release of Oracle Solaris Cluster 3.3.05/11 Update 1 Juergen Schleich blogs that the package version of the Oracle Solaris Cluster 3.3 05/11 Update1 is the same for the core framework and the agents as for Oracle Solaris Cluster 3.3. Therefore, he points out, it's possible to patch up an existing Oracle Solaris Cluster 3.3. On the other hand, he continues, the package version of the Oracle Solaris Cluster Geographic Edition 3.3 05/11 Update1 is NOT the same as Oracle Solaris Cluster Geographic Edition 3.3, although it's possible to upgrade the Geographic Edition 3.3 without interruption of the service. Schleich's blog includes an extensive list of patch revisions for both Solaris 10 10/09 Update8 or higher and for Solaris 10 x86 10/09 Update8 or higher.

The three-minute demo of MySQL Enterprise Edition is designed to help viewers understand how the solution reduces the risk, cost and time required in developing, deploying and managing business-critical MySQL applications. The Webinar on MySQL 5.6 (one of five parts) covers the improvements to Performance, InnoDB, Replication, Instrumentation and flexibility with NoSQL (Not Only SQL) access. The Webinar on MySQL Essentials reviews the versatility of MySQL Workbench, a visual database modeling and design tool, a SQL editor, and an administrative tool.
Cloud Computing
Get into the Cloud but Stay Out of Trouble
Four Tips for Regulatory Compliance
While cloud computing, whether public or private, offers clear benefits to users, there are nevertheless a few perils involved that need to be addressed. Regulatory compliance is one of them, and Jim Buchanan's InfoWorld article "Cloud computing: 4 tips for regulatory compliance" presents some ideas on keeping one's corporate head above water when it comes to compliance:

  • Be aware of new challenges the cloud may add to the IT workload
  • Track the fast-changing standards landscape
  • Pay attention to the requirements of SLAs
  • Make security a priority
Setting Up Unison File Synchronization Between Two Servers
Unison Tracks/synchronizes Changes in Both Directions
In the tutorial "Setting up unison File Synchronization Between Two Servers on Debian Squeeze" Falko Timme provides a five-step approach, beginning with the information that "Unison is a file-synchronization tool similar to rsync, but the big difference is that it tracks/synchronizes changes in both directions, i.e., files changed on server1 will be replicated to server2 and vice versa." The steps (and code is provided) are:

  • The preliminary note concerning Unison as root
  • Installing Unison
  • Creating a Private/Public Key pair on server1
  • Running Unison
  • Creating a Cron Job (which Timme does in order to automate synchronization)

Timme runs Unison as the root user in this tutorial so that Unison has sufficient permissions to synchronize user and group permissions.

Gartner Hype Cycle for Storage Technologies 2011
Evaluates 43 storage hardware and storage software technologies
The Gartner Hype Cycle report on storage technologies illustrates the typical lifecycle that a new storage technology experiences (categorized as "maturity levels") prior to reaching mainstream adoption. This year's report, co-authored by Pushan Rinnen and Dave Russell, assesses each of the 43 storage hardware and software technologies included in terms of benefit rating; market penetration; maturity; and vendor sources. Users will find the information helpful in determining where and when to invest.
Storage Strategies NOW Survey Finds 70% of Respondents Planning to Deploy SSDs
Lower Power Consumption; Need to Reduce Response Times; Reliability Prove Compelling
The industry survey "Solid State Drives and High-Speed Memory: Adoption, Practice and Deployment," conducted by Storage Strategies NOW, found more than 70% of respondents planning to deploy solid state drives and high-speed memory. Factors cited as motivating the move included lower power consumption; need to reduce response times; reliability; and improved user experience. Factors impeding the move included high cost per Gigabyte (GB); write endurance; wear-leveling; IOPs read/write performance; latency; and availability/reliability, among other lesser reasons.
SATA Group Creates New High-speed Storage Spec
PCI Device Interface Boosts Speeds to 8Gb/s and 16Gb/s
The Serial ATA International Organization (SATA-IO) has announced a new PCI Express (PCIe)-based interconnect specification designed to boost interface throughput of solid state drive (SSD) technology from 6GB/sec to 8Gb/sec and 16Gb/sec writes Lucas Mearian in Computerworld. The new SATA Express specification is said to protect investments in current SATA and PCIe products because it's a hybrid of both and still looks like SATA to the host system. The specification will define new device and motherboard connectors that will support both new SATA Express and current SATA devices, Mearian notes.

    LibreOffice 3.3.4 is Ready for Download
    Development Work Continues on LibreOffice 3.4
    The Document Foundation announces that LibreOffice 3.3.4, a new release of the free office suite’s 3.3 branch, is available for download.

The Document Foundation maintains two editions of LibreOffice: version 3.3.x caters to conservative users, who wish to stick to a proven release in deep maintenance mode, with increasingly infrequent updates, while the 3.4 branch provides a more modern and featureful release. Development is continuing on the 3.4 series, which offers new features. The next version in that branch – LibreOffice 3.4.3 – is expected by the end of August. LibreOffice 3.3.4 is available for Windows, Mac OS X and Linux, in over 100 different languages (more than twice the language coverage of comparable proprietary products).
