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..."

15 Jun 2013 SPARC T5-8 Delivers Best Single System SPECjEnterprise2010 Benchmark running WebLogic 12c [31404]
27,843.57 SPECjEnterprise2010 EjOPS

Oracle produced a world record single-server SPECjEnterprise2010 benchmark result of 27,843.57 SPECjEnterprise2010 EjOPS using one of Oracle's SPARC T5-8 servers for both the application and the database tier.

  • The SPARC T5-8 server ran the Oracle Solaris 11.1 operating system and used Oracle Solaris Zones to consolidate eight Oracle WebLogic application server instances and one database server instance to achieve this result. The IBM system used LPARS and AIX V7.1.

  • This result demonstrated less than 1 second average response times for all SPECjEnterprise2010 transactions and represents JEE 5.0 transactions generated by 227,500 users.

  • The application server used Oracle Fusion Middleware components including the Oracle WebLogic 12.1 application server and Java HotSpot(TM) 64-Bit Server VM on Solaris, version 1.7.0_15. The database server was configured with Oracle Database 11g Release 2.

  • The 8-chip SPARC T5 processor based server is 2.6x faster than the 8-chip IBM POWER7+ processor based server.

15 Jun 2013 Comparing Solaris 11 Zones to Solaris 10 Zones [31399]
Solaris 10 Whole-Root, Solaris 10 Sparse-Root, Solaris 11, Solaris 11 Immutable Zones

Jeff Victor writes, "Many people have asked whether Oracle Solaris 11 uses sparse-root zones or whole-root zones. I think the best answer is "both and neither, and more" - but that's a wee bit confusing. This blog entry attempts to explain that answer.

First a recap: Solaris 10 introduced the Solaris Zones feature set, way back in 2005. Zones are a form of server virtualization called "OS (Operating System) Virtualization." They improve consolidation ratios by isolating processes from each other so that they cannot interact. Each zone has its own set of users, naming services, and other software components. One of the many advantages is that there is no need for a hypervisor, so there is no performance overhead. Many data centers run tens to hundreds of zones per server!..."
