Overview of Process Scheduling Classes in the Oracle Solaris Kernel [33548]
by Brian Bream

Brian Bream writes, "The Oracle Solaris kernel has a number of process scheduling classes available.

Timesharing (TS) This is the default class for processes and their associated kernel threads. Priorities in the class are dynamically adjusted based upon CPU utilization in an attempt to allocate processor resources evenly.

Interactive (IA) This is an enhanced version of TS. Some texts reference this in conjunction with TS, i.e. TS/IA. This class applies to the in-focus window in the GUI. It provides extra resources to processes associated with that specific window.

Fair Share Scheduler (FSS) This class is 'share based' rather than priority based. The threads associated with this class are scheduled based on the associated shares assigned to them and the processor's utilization..."

How to Set Up a Hadoop Cluster Using Oracle Solaris [33364]
Hands-On Labs of the System Admin and Developer Community of OTN by Orgad Kimchi

Orgad Kimchi presents a hands-on lab presents exercises that demonstrate how to set up an Apache Hadoop cluster using Oracle Solaris 11 technologies such as Oracle Solaris Zones, ZFS, and network virtualization. Key topics include the Hadoop Distributed File System (HDFS) and the Hadoop MapReduce programming model:

Lab Introduction

We will also cover the Hadoop installation process and the cluster building blocks: NameNode, a secondary NameNode, and DataNodes. In addition, you will see how you can combine the Oracle Solaris 11 technologies for better scalability and data security, and you will learn how to load data into the Hadoop cluster and run a MapReduce job.


This hands-on lab is appropriate for system administrators who will be setting up or maintaining a Hadoop cluster in production or development environments. Basic Linux or Oracle Solaris system administration experience is a prerequisite. Prior knowledge of Hadoop is not required.

System Requirements

This hands-on lab is run on Oracle Solaris 11 in Oracle VM VirtualBox. The lab is self-contained. All you need is in the Oracle VM VirtualBox instance.

Elfsign Object Signing on Solaris [33292]
Verify that binaries are as they should be

Dan Anderson writes, "Solaris elfsign(1) is a command that signs and verifies ELF format executables. That includes not just executable programs (such as ls or cp), but other ELF format files including libraries (such as and kernel modules (such as autofs). Elfsign has been available since Solaris 10 and ELF format files distributed with Solaris, since Solaris 10, are signed by either Sun Microsystems or its successor, Oracle Corporation.

When an ELF file is signed, elfsign adds a new section the ELF file, .SUNW_signature, that contains a RSA public key signature and other information about the signer. That is, the algorithm used, algorithm OID, signer CN/OU, and time stamp. The signature section can later be verified by elfsign or other software by matching the signature in the file agains the ELF file contents (excluding the signature)..."

solaris10 Brand Zone Clusters [33193]
released in Oracle Solaris Cluster version 4.1

Krishna K Murthy writes, "The solaris10 brand zone cluster, released in Oracle Solaris Cluster version 4.1 software, provides a virtualized Oracle Solaris 10 cluster environment in an Oracle Solaris 11 configuration. Using this feature enables customers to run or migrate cluster applications that are deployed on the Oracle Solaris 10 operating system, without any modification to the application.

The following diagram depicts the coexistence of Oracle Solaris 11 and Oracle Solaris 10 cluster applications, which are isolated by using the zone cluster feature..."

The Best x86 Platforms for Oracle Solaris [33100]
Oracle x86 Systems

With adoption in over 50,000 businesses and institutions, Oracle Solaris has clearly established itself as the world leader in UNIX-based operating systems. Oracle Solaris includes many unique and innovative technologies that are not commonly available in other operating systems, such as Oracle Solaris ZFS, Dynamic Tracing (DTrace), predictive fault detection, built-in virtualization, and advanced security.

As a result of a broad strategic alliance between Oracle and Intel, Oracle Solaris has become widely deployed on Intel-based x86 systems from a variety of different hardware vendors. Intel has embraced Oracle Solaris as a mainstream UNIX operating system for enterprise-class, mission-critical systems based on Intel Xeon processors.
