Blog Explains Parallel Backup Operations in MySQL Enterprise Backup v3.8.0
Pipeline Processing Enables Parallelism, Speeds Backups
In a post on parallel backup in MySQL Enterprise Backup (MEB) v3.8.0 jothir (Hema Sridharan) explains how read/write operations are now performed in parallel using pipeline parallelism. The post explains that the pipelined parallel execution of read, process (if requested) and write operations is achieved by invoking multiple threads for different operations and usage of buffers. Each operation is split into segments, and threads operate on different segments from different iterations concurrently. Each segment is assigned one or more worker threads and in-queue buffers which store the work to be processed by that stage. The post provides an example.

Oracle Collaborates on Drafting Specifications for Cloud Management Standards
Two Specification Drafts Issued: PaaS and IaaS Service Models
Oracle has collaborated with a number of leading technology vendors in the IT industry to draft two key specifications for cloud management standards, Anand Akela reports. One focuses on the Platform as a Service (PaaS) model; the other on the Infrastructure as a Service (IaaS) model. The collaborators announced that their "Cloud Application Management for Platforms" (CAMP) will be submitted to OASIS for consideration in an effort to ensure interoperability for deploying and managing applications across cloud environments. Akela also notes the release by the Distributed Management Task Force ( DMTF ) of the new Cloud Infrastructure Management Interface (CIMI) specification.

Best Practices for Securely Deploying the SPARC SuperCluster T4-4
Exploiting the Balance Between Security and Configurational Flexibility
The architectural, deployment and operational best practices for utilizing the security capabilities of the SPARC SuperCluster T4-4 are outlined in a post by Glenn Brunette, Ramesh Nagappan and Joel Weise. The authors highlight the comprehensive set of security controls in the SPARC SuperCluster platform that can be employed to meet even the most challenging security demands. They also offer guidance on where and how the SPARC SuperCluster platform can be integrated into an existing IT security environment. The SPARC SuperCluster is unique in its balance between the tight integration of its components and its level of configuration and operational flexibility.
Revision to SPARC Architecture Released
Essential to Understanding the Operation of the SPARC Processor
Darryl Gove draws attention to the release of the updated "Oracle SPARC Architecture 2011," a document essential for those interested in the behavior of a SPARC processor. This publication supersedes the SPARC v9 book, which was published in the 90s. Describing its scope, the document collects in one volume the nonprivileged (Level 1) architecture from SPARC V9; most of the privileged (Level 2) architecture from SPARC V9; and provides more in-depth coverage of all SPARC V9 features. Moreover, the book includes all of the architectural extensions (beyond SPARC V9), developed through the processor generations of UltraSPARC III, IV, IV+ and T1.

    Licensing Open Source Code in the Modern, Post-revolutionary Era
    Cantrill Maintains GPLv2's Days are Numbered
    Peace reigns in the open source arena, Bryan Cantrill maintains in his post on the need to move from GPLv2 licensing to the more open-source friendly MPLv2. The experience of VLC, which recently relicensed its core software to LGPLv2 to allow it, as Cantrill writes, " ... to be more readily shared with other projects," bears this out, he explains. A new generation of developers are convinced that open source has won the battle with proprietary software. There was general agreement with his position at Forum Internacional Software Livre in Brazil, where he first voiced his thoughts.

    Oracle's SPARC T4-2 Produces World Record Oracle Essbase Aggregate Storage Benchmark
    Bests Mark Set by SPARC Enterprise M5000 Server

    Oracle's SPARC T4-2 Server (2 cpus), configured with a Sun Storage F5100 Flash Array and running Oracle Solaris 10 with Oracle Database 11g and Oracle Essbase 11.1.2.2.100, outperformed Oracle's SPARC Enterprise M5000 server (4 cpus) with Oracle Essbase 11.1.1.3 on Oracle Solaris 10 by 80%, 32% and 2x performance improvement on Data Loading, Default Aggregation and Usage Based Aggregation, respectively. The SPARC T4-2 server achieved sub-second query response times for 20,000 users in a 15 dimension database and aggregated and stored values for a 15 dimension cube in 398 minutes with 16 threads and in 484 minutes with 8 threads.

    Creating an Active/Active IPMP for Solaris 11
    Procedure Explains Network Auto Magic Service

    User 20121221 blogs on how to create an active/active ipmp configuration with Solaris 11, in which automated network configuration is managed by a Solaris service called "nwam" or "Network Auto Magic". The nawm service is turned on by default, the post explains, and must be disabled before you make changes to the settings for static IP addresses. One must also employ the "default" physical networking service and be aware that this disables the ipv6 on the interfaces, which persists across reboots. The post notes that the ipadm command is the preferred tool to manage the configuration of the interfaces.
