Oracle Releases Oracle Solaris 10 1/13 [30069]
Still Plenty of Life Left in the Old OS

Among the attributes of the recently released Oracle Solaris 10.1.13 are the inclusion of the Oracle Solaris Zones Preflight System Checker; the Oracle Solaris Live Upgrade Preflight Checker; and improved transfer speed rates for SSH, SCP, and SFTP in moderate (50ms) to high latency environments. Oracle testing shows scp transfer times of Oracle Solaris 10 1/13 are 1/8 the times of a similarly configured Oracle Solaris 10 8/11 system for multi-megabyte file transfers. Read Glynn Foster's post to learn about the abundant life still left in Oracle Solaris 10 OS.

Myth Busters Department: 'A Solaris tmpfs Uses Real Memory' [29967]
Alan Hargreaves Demonstrates the Truth of His Assertion

Whatever you may have heard, Alan Hargreaves establishes that a Solaris tmpfs uses real memory. This is because, he asserts, a tmpfs uses pageable kernel memory although, if necessary, these pages can be paged to the swap device: a guaranteed result if you put more data onto a tmpfs than you have physical memory. For the skeptics, Hargreaves provides a three-step test that demonstrates what happens in free memory when a user creates a 1GB file in /tmp. Whatever one may have thought, he concludes, tmpfs does not steal some of the disk allocated as swap to use as a filesystem without impacting memory.

Since You Asked... A Couple of Oracle Solaris Resources [29969]
IBM AIX to Solaris Migration and Oracle Solaris on Oracle x86 Systems

Larry Wake recommends two Oracle Solaris Resources: "IBM AIX to Oracle Solaris Technology Mapping Guide" and "Oracle's x86 Systems: The Best x86 Platforms for Oracle Solaris." The first title is a 55-page technical white paper identifying and comparing the differences between AIX 7.1 and Oracle Solaris 11. The second was the featured topic on the February 26th webcast on Oracle Solaris on Oracle's x86 systems, which mentioned the bidirectional connection between Oracle Solaris and x86 systems' service processors, and the accompanying white paper mentioned above covers the Oracle Solaris-Aware Service Processor, and other details as well. The webcast itself is now available for replay.

Oracle Delivers Unique Value with Oracle Solaris: IDC White Paper [29784]
IDC Takes a Second Look at Oracle Solaris and Customer Attitude

In his comments on the revised IDC white paper "Oracle Delivers Unique Value with Oracle Solaris" Larry Wake remarks on its highlighting of how Oracle Solaris 11 is optimized for cloud computing, with unique virtualization, scaling, and provisioning capabilities, evidence, Wake notes, of Oracle's increased investment in Solaris since the Sun acquisition. White paper co-authors Gary Chen and Al Gillen include a case study based on the experience of Synodex, a medical records processing company that adopted Solaris 11 early. The white paper also notes a revitalized level of customer confidence in Oracle Solaris since 2010 vis-a-vis competitive major Unix solutions.

How to Configure a Failover Guest Domain in an Oracle Solaris Cluster [29690]
Oracle VM Server Provides Protection to Guest Domains Against Outages, Planned and Unplanned

Venkat Chennuru posts at length in an article that provides a step-by-step example of how to deploy an Oracle VM Server for SPARC guest domain in a highly available failover setup with a two-node Oracle Solaris Cluster 4.1 with a global file system on Oracle Solaris 11.1. The post also explains how to verify that the cluster is behaving correctly by switching over the failover guest domain from the primary node to the secondary node and back. Chennuru writes that the automated failover of a guest domain through restart on an alternate cluster node enables the protection of guest domains from planned and unplanned downtime.
