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!..."

Monitoring per Zone Filesystem activity [31401]
fsstat(1M)
Solaris 11 added a new at fsstat(1M) monitoring command that provided the ability to view filesystem activity at the VFS layer (ie filesystem independent). This command was available in Solaris 11 Express and the OpenSolaris releases as well.
In Solaris 11.1 support was added for per Zone and aggregated information so now we can very quickly determine which zone it is that is contributing to the operations...

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.

Using DTrace on Oracle Linux [31298]
An introduction to DTrace probes and providers for Oracle Linux and how they are different from those in Oracle Solaris.
Richard Friedman writes, "DTrace is a comprehensive dynamic tracing facility originally developed for the Oracle Solaris operating system, and it is now available to Oracle Linux customers. DTrace is designed to give operational insights that allow users to tune and troubleshoot the operating system and applications dynamically in real time. DTrace provides Oracle Linux developers with a tool to analyze performance and track down performance problems across the software stack. DTrace enables higher quality applications development, reduced downtime, lower cost, and greater utilization of existing resources. It is available for download from the Unbreakable Linux Network for Oracle Linux Support customers..."

Instant Automated Installer Zone for Oracle Solaris 11.1 [31299]
By Larry Wake
Larry Wake writes, "One of the biggest differences between Oracle Solaris 11 and previous releases is how provisioning tasks are handled. It's safe to say that just about any installation or update function you can think of has gotten at least an order of magnitude faster, easier, safer, smarter and more powerful -- but still, there's that word "different" ... .
The key new provisioning technology, as you may already know, is the Image Packaging System (IPS). It's the framework for installation, maintenance and removal of software on an Oracle Solaris 11 system. Another key technology is the Automated Installer (AI), which replaces JumpStart for hands-free installation of large numbers of systems.
We've just introduced something new to make it easier to start working with AI..."
