Hadoop on an Oracle SPARC T4-2 Server [32747]
simultaneously run up to 64 software threads

Jeff Taylor sales he "recently configured a Oracle SPARC T4-2 server to store and process a combination of 2 types of data:

  • Critical and sensitive data. ACID transactions are required. Security is critical. This data needs to be stored in an Oracle Database.

  • High-volume/low-risk data that needs to be processed using Apache Hadoop. This data is stored in HDFS.

Based on the requirements, I configured the server using a combination of:

  • Oracle VM Server for SPARC, used for hard partitioning of system resources such as CPU, memory, PCIe buses and devices.

  • Oracle Solaris Zones to host a Hadoop cluster as shown in Orgad Kimchi's How to Set Up a Hadoop Cluster Using Oracle Solaris Zones

The configuration is shown in the following diagram:..."

Top 10 signs your CIO isn't ready for the modern web [32655]
From Scott McNealy

Barb Darrow writes, "Earlier this summer, Sun Microsystems co-founder Scott McNealy trotted out an old chestnut - a top ten list - on how you can tell your CIO is clueless about the modern web.

A quick sampler from his talk at ForgeRock Open Identity Stack Summit: Your CIO is web-dopey if he thinks Big Data is a rapper; that COBOL programming is prerequisite for all new hires; and considers Computer Associates an open-source software company..."

Embedded Software: Disruptions Ahead [32182]
Blog Post by Terrence Barr

Terrence Barr, Senior Technologist and Principal Product Manager for Oracle's small embedded Java Products, writes, "There is an interesting discussion happening on the LinkedIn 'Internet of Things' group right now, in response to the InfoWorld article a few days ago titled 'Oracle hitches Java to "Internet of things"'.

The discussion touches on some interesting details on why Java may or may not be a good choice for embedded. Besides the fact that Java is already proven to be one of the most widely deployed embedded technologies ('10 billion and Counting..") I think the discussion misses a key point: The coming disruptive shift in the embedded industry..."

Availability Best Practices - Avoiding Single Points of Failure [31784]
By Jeff Savit

Jeff has written a post that is one of a series of "best practices" notes for Oracle VM Server for SPARC (formerly named Logical Domains) Avoiding Single Points Of Failure (SPOF).

He says, "Highly available systems are configured without Single Points Of Failure (SPOF) to ensure that individual component failures do not result in loss of service. The general method to avoid SPOFs is to provide redundant components for each necessary resource, so service can continue if a component fails. In this article we will discuss resources to make resilient in Oracle VM Server for SPARC environments. This primarily consists of configuring redundant network and disk I/O. Subsequent articles will drill down into each resource type and provide comprehensive illustrations."

Topics include:

  • Network availability
  • Disk availability
  • Service Domain Availability Using Multiple Service Domains

In summary, Jeff writes, "Oracle VM Server for SPARC lets you configure resilient virtual network and disk I/O services, and provide resiliency for the service and I/O domains that provision them. Following articles will show exactly how to configure such domains for highly available guest I/O."

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..."

As The World 'Goes Software,' Oracle Has An Upside In Hardware [31099]
Mark Peters, ESG Analyst

Mark Peters is an ESG senior analyst focused on storage systems. In a recent blog post, he writes, "Late last month Oracle held its annual event for the analyst community. Ensconced with a range of my peers I was immediately struck by how few of the audience I recognized compared to other events of this type that I get to attend. I stopped to think about it and realized that the reason was simple - there was a large preponderance of the attendees that, in one way or another, were focused on software. Now, this might be one of the bigger 'duh' moments of my life and also of your reading experience. So why am I mentioning it here? Because what it demonstrates is actually the importance of other things....err, like hardware in general and storage in particular. As we know from all those Oracle ads telling us that 'x' of the top 'y' companies in any given vertical (where x and y are invariably identical numbers) use its databases, Oracle has largely won that war. The opportunities for Oracle to make significant progress in terms of market share and revenue lie in markets that it does not yet dominate..."
