Finding the Path from RHEL 6 to Oracle Solaris 11 [27026]
Mapping Guide Shows the Way

A post on oracle.com offers advice to those moving from RHEL to Oracle Solaris OS in the form of a mapping guide between RHEL 6 and Solaris 11. For each general technology area, the author lists the main features of Oracle Solaris 11, their advantages, and how the command lines and configuration files map between the two operating systems - whether it's between RPM and IPS, KVM and Oracle Solaris Zones, Upstart and the Service Management Facility (SMF). The guide is designed to give administrators familiar with Red Hat Enterprise Linux a first step on where to get more information.

Some Better Disk Backend Choices [26950]
What's Up with LDoms, Part 3

In "What's Up with LDoms,Part 3" Stefan Hinker looks at disk backend choices, reminding readers that, in his earlier postings, he had used a ZFS volume as a backend for the boot disk of mars. In this segment, Hinker examines some of the other ways to store the data of virtual disks. These include physical LUNs, in any variant that the Control Domain supports, including SAN, iSCSI, SAS, and the internal disks of the host system; Logical Volumes like ZFS Volumes, but also SVM or VxVM; Regular Files, which can be stored in any filesystem accessible by the LDoms subsystem.

Using the Integrated Load Balancer in Oracle Solaris 11 [26782]
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 [26783]
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.
