Using the Integrated Load Balancer in Oracle Solaris 11
Example Illustrates Setting up Virtual Server Across Two Oracle Solaris Zones
The OTN article "How to Set Up a Load-balanced Application Across Two Oracle Solaris Zones," begins with an overview of the Integrated Load Balancer (ILB) feature of Oracle Solaris 11. The author proceeds to an example of setting up a virtual Apache Tomcat server instance in the half-NAT mode, in which the ILB, as traffic hits it, re-writes the destination IP address of the real server, preserving the source IP address. Incoming traffic is load-balanced to the virtual server across two zones, each running the Apache Tomcat Server while the load balancer itself is configured as a multihomed zone.
Unraveling Thread Placement Policies on NUMA Systems
There's Been a Change since Solaris 10

Blogger Dave Dice takes issue with the view that initial thread placement onto resources is process agnostic. He describes an experiment that suggests it is not thread creation time, but rather process membership that determines thread placement. Dice continues, reporting that the Solaris team explained that the kernel is no longer using a simple maximum dispersal policy, but instead thread placement is now process membership-aware. Even with a policy that allows process-aware packing, however, placement reverts to spreading threads onto other nodes if a node becomes too saturated, he points out.

Oracle ACE Director Ronald Bradford on MySQL Connect
Comments as well on MySQL 5.6
Ronald Bradford, an Oracle ACE Director, explained to interviewer Keith Larson what his plans are for future MySQL Connect events and commented on the benefits to both the community and to Oracle of having MySQL content at events like Oracle Open World. With respect to MySQL 5.6, Bradford praised the optimizer trace feature for its capability in making exposed information visible, both in itself and in the capability of applying information discerned for optimizing SQL statements in earlier versions of MySQL. He was also enthusiastic about the improvements in instrumentation in the Performance Schema and the numerous replication features.

Oracle Cluster File System 2 (OCFS2)
A Brief History and a Glance at the Future

When users of the first version of the Oracle Cluster FileSystem (OCFS) began demanding the sort of features found in a normal native filesystem, (a real general purpose cluster filesystem), OCFS2 was the result, according to Wim Coekaerts. OCFS2 is very easy to use, he writes, in part because of the simple text file that contains the node information (hostname, node number, cluster name) and a file that contains the cluster heartbeat timeouts. OCFS2 today, in the mainline kernel, is pretty much feature complete in terms of integration with every filesystem feature Linux offers, Coekaerts avers.

Oracle Linux 6 update 3
OL6.3 contains UEK2 kernel-uek-2.6.39-200.24.1

Oracle Linux 6.3 is now available online, Wim Coekaerts posts on his blog, including both base channels and the latest channels, and the repositories as well. Source RPMs (.srpm), Coekaerts reports, are also being uploaded. Oracle Linux 6.3 contains Unbreakable Enterprise Kernel 2 kernel-uek-2.6.39-200.24.1, he notes, adding that complete source, complete changelog, complete checkin history, both mainline and our own, are now available in a single spot. Coekaerts announces another upcoming feature, which is a boot iso for OL6.3 that boots up uek (2.6.39-200.24.1) as install kernel and uses btrfs as the default filesystem for installation.

Garmin Positions Itself on Oracle Exadata Dataase Machine
Experiences 50% Boost in Performance
Garmin International has migrated its infrastructure that powers the company’s Oracle Advanced Supply Chain Planning and the Garmin fitness segment to Oracle Exadata Database Machine. The latter segment provides customers with an online platform to store, retrieve, and interact with data captured using Garmin fitness products, according to Javier Puerta. The environment, which is built on an Oracle Database, processes approximately 40 million queries per week.Garmin moved to Exadata, Puerta writes. Customers had begun experiencing reliability issues with Garmin's legacy infrastructure, which prompted the company's migration to Oracle Exadata Database Machine.

What's up with LDoms: Part 1 - Introduction & Basic Concepts
Stefan Hinker Updates the Documentation on Oracle VM Server for SPARC
Stefan Hinker has launched a primer series updating the earlier LDoms Admin Guide and Tony Shoumack's 2007 "Beginner's Guide to LDoms" in which he explains how hypervisors running on x86 hardware differ from those embedded in SPARC firmware, which is to economize on the number of OS threads assigned to CPUs in order to concentrate on their principal function: maintaining isolation between guests. Hinker demonstrates the configuration of the control domain and the freeing up of considerable amounts of CPU and RAM for guest systems while also creating the necessary infrastructure that allows guests system interaction with the outside world.

An introduction to Oracle's new StorageTek SL150 Modular Tape Library will be presented on Thursday, July 12, 2012 at 3pm CET (2pm GMT), in a 60 minute webcast, Cinzia Mascanzoni reports. This is the first scalable tape library designed for small and midsized companies experiencing high growth. The StorageTek SL150 Modular tape library is built from Oracle software and StorageTek library technology to deliver a cost-effective combination of ease of use and scalability, resulting in lower TCO. Viewers can submit questions via WebEx chat, and there will be a live Q&A session at the end of the webcast, Mascanzoni writes.

    Downloads of Apache OpenOffice 3.4.0 Soar
    More than 5 million in a Mere Six Weeks
    Within six weeks of its release, downloads of Apache 3.4.0 Open Office have exceeded five million, LinuxBSDos.com reports, phenomenal for software that is no longer installed by default on Linux distros. Apache Open Office is the renamed LibreOffice, LiuxBSDos.com reminds readers, and was the first version released since it became an Apache Software Foundation (ASF) incubating project., and coding continues on 3.4.1, scheduled for release in late July. Following the release of 3.4.1, ASF is contemplating either a slower, more incremental merge of Symphony enhancements into OpenOffice, or a more rapid rebasing of OpenOffice on top of Symphony.

    'Red Hat Enterprise Linux to Oracle Solaris Porting Guide': OTN White Paper
    Covers Information Useful for Users of Debian, Suse, Ubuntu or Centos as well
    Commenting on the recently published Oracle white paper "Red Hat Enterprise Linux to Oracle Solaris Porting Guide," available on OTN, Joerg Moellenkamp describes it as an "interesting document" that covers not only RHEL but contains as well information helpful to users of Debian, Suse, Ubuntu or Centos. He writes that the paper covers what one should consider when you want to port your application (or just script) from RHEL to Oracle Solaris 11. Admins, he says, will find the section that describes where the gnu tools are located and the differences between Solaris native commands and their gnu counterparts.
