04 Sep 2013 Administering Solaris Zones [32741]
An excerpt from Chapter 17 of Oracle Solaris 11 System Administration Exam Guide

This is an excerpt from Chapter 17, "Administering Solaris Zones," of Oracle Solaris 11 System Administration Exam Guide by Michael Ernest (McGraw-Hill Professional; 2013) with permission from McGraw-Hill. Download a PDF of the full chapter. Also, read a Q&A with the author.

"You are about to learn how to create and configure a Solaris Zone, observe it in its various states of being, and manage it as it runs on your system. For those of you who need to get on with learning about other virtualization techniques available on Solaris and other operating systems, learning how zones work will give you a solid conceptual foundation for those subjects.

You've been learning about zones already -- or at least the key parts that make up one. For example, you've learned to configure projects, an abstraction for treating a group of processes as a workload. You've learned how to set limits with process, task, and project resource controls, and you've learned about global resource controls such as memory caps, process scheduling, and CPU provisioning. You can create a new ZFS file system with its own property controls for any occasion you deem fit. And you know that you can now create virtual NICs whenever you need a new logical network resource..."

02 Sep 2013 So, what makes Solaris Zones so cool? [32746]
Karoly Vegh Provides 10 Reasons

Karoly Vegh writes, "This post is about the third option, a container technology built right into Solaris: Solaris Zones. They are pretty awesome, especially on Solaris 11 - they're like vacation: once you go Zones, you won't want to leave them :) But what exactly makes Zones so cool?

There are a number of reasons, allow me to list my favourite top 10:..."

  • Solaris Zones are performance overheadless
  • Resource Management
  • the Golden Image cloning
  • Zone independence
  • Branded Zones
  • Cluster integration
  • Immutable Zones
  • Exclusive IP stack with VNICs
  • zonestat
  • Per-zone fstype statistics

01 Aug 2013 READ_ME_FIRST: What Do I Do with All of Those SPARC Threads? [32054]
What to do with the 1,536 threads in an Oracle M5-32 system

"With an amazing 1,536 threads in an Oracle M5-32 system, the number of threads in a single system has never been so high. This offers a tremendous processing capacity, but one may wonder how to make optimal use of all these resources.

In this technical white paper, we explain how the heavily threaded Oracle T5 and M5 servers can be deployed to efficiently consolidate and manage workloads using virtualization through Oracle Solaris Zones, Oracle VM Server for SPARC, and Oracle Enterprise Manager Ops Center, as well as how to improve the performance of a single application through multi-threading..."

27 Jun 2013 How to Set Up a MongoDB NoSQL Cluster Using Oracle Solaris Zones [31586]
On an x86-Based System; Solaris Zones; SMF; DTrace; 3-node cluster

Orgad Kimchi has written a brief overview of MongoDB and follows with an example of setting up a MongoDB three nodes cluster using Oracle Solaris Zones.

He says, "The following are benefits of using Oracle Solaris for a MongoDB cluster:

  • You can add new MongoDB hosts to the cluster in minutes instead of hours using the zone cloning feature. Using Oracle Solaris Zones, you can easily scale out your MongoDB cluster.

  • In case there is a user error or software error, the Service Management Facility ensures the high availability of each cluster member and ensures that MongoDB replication failover will occur only as a last resort.

  • You can discover performance issues in minutes versus days by using DTrace, which provides increased operating system observability. DTrace provides a holistic performance overview of the operating system and allows deep performance analysis through cooperation with the built-in MongoDB tools.

  • ZFS built-in compression provides optimized disk I/O utilization for better I/O performance. In the example presented in this article, all the MongoDB cluster building blocks will be installed using the Oracle Solaris Zones, Service Management Facility, ZFS, and network virtualization technologies..."

27 Jun 2013 Boot Environments for Solaris 10 Branded Zones [31580]
Now add and patch packages to boot environments of a Solaris 10 Branded Zone

Jeff Victor writes, "Until recently, Solaris 10 Branded Zones on Solaris 11 suffered one notable regression: Live Upgrade did not work. The individual packaging and patching tools work correctly, but the ability to upgrade Solaris while the production workload continued running did not exist. A recent Solaris 11 SRU (Solaris 11.1 SRU 6.4) restored most of that functionality, although with a slightly different concept, different commands, and without all of the feature details. This new method gives you the ability to create and manage multiple boot environments (BEs) for a Solaris 10 Branded Zone, and modify the active or any inactive BE, and to do so while the production workload continues to run..."
