Oracle Solaris ZFS and Sun Fire Storage Stores NASA Solar Images
Holds 144TB of Data for Further the Study of the Sun and Solar Activity
Oracle Solaris ZFS and Sun Fire storage server are helping warehouse close-up pictures of the real Sun for the University of Central Lancashire which is distributing NASA-supplied solar images from a new solar observation satellite designed to study the Sun and solar activity.
Root as A Role and Beyond
Improved Access Control in OpenSolaris
The use of Root as a Role to tighten auditing processes is the subject of Brian Leonard's blog on that topic. Root is one of the roles pre-configured in OpenSolaris, Leonard writes, which is an invitation to wholesale logging on as root, though that practice can be somewhat moderated by the use of role based access control (RBAC). It is the case, Leonard continues, that with root configured as a role, the need to gain access to the root password diminishes in value. The need to use one's account password helps with the accountability for any actions performed as root, he notes.
New DTrace Providers in OpenSolaris
Covers the TCP and UDP Protocol Implementations

DTrace TCP and UDP providers with probes for send and receive events were expected to be added to build 142 of OpenSolaris. The TCP provider contains probes for TCP state machine transitions and significant events in connection processing (connection request, acceptance, refusal, etc). The UDP provider contains probes which fire when a UDP socket is opened/closed. These providers cover the TCP and UDP protocol implementations.

Oracle Support Communities
Login and Engage with Peers on the Latest Oracle Technologies

There are more than 140 online Oracle Support Communities where participants can learn more about a particular technology - such as the Oracle Solaris Cluster - ask specific questions regarding issues they may be having, or share their knowledge and help grow the communities' think tank.

Still Using MySQL 5.0?
Security Updates Make this a Good Time to Move to 5.1
MySQL 5.0 is currently in Extended Support state, blogs Giuseppe Maxia, which means that the binaries are not in the main download pages, but only in the archives. As stated in the MySQL Lifecycle Policy, according to Maxia, only serious security bugs are fixed, and the binaries are provided at the company's discretion. Time for an upgrade to 5.1.? He thinks so.
Cloud Computing
Data Integrity in the Cloud
Drive Reliability as a Limitation
Henry Newman's ability to analyze complex systems and explain them in accessible terms was most recently applied to a discussion of cloud storage that blogger Marc Hamilton drew attention to. Newman's article "Cloud Storage Will Be Limited by Drive Reliability, Bandwidth," which appeared in, explains the statistical reasons behind the inadequacy of a multi-petabyte cloud storage environment that relies only on data replication across two sites to protect data, as Hamilton summarizes the argument.
Oracle Solaris Studio Express 6/10
New Release Comes with Build, Debugging, and Tuning Improvements
Just released June 3 is the Oracle Solaris Studio Express 6/10, formerly Sun Studio Express, and its Customer Feedback Program. The new release is available on Solaris 10 (SPARC, x86), OEL 5 (x86), RHEL 5 (x86), SuSE 11 (x86) and will be available for OpenSolaris in the near future. Its compilers, libraries and tools have been tuned and optimized to support the latest architectures. There also are enhanced debugging and code coverage tooling as well as improved application profiling and observability. Its integrated IDE has been updated and is now based on NetBeans 6.8.
Sun SPOT Repriced
The Sun Small Programmable Object Technology Project Still Active
Sun SPOT devices have been repriced and they are selling out fast. As of this writing, there were still availability for Sun SPOT Java Development Kits for commercial orders only in the United States and Canada at the selling price of US$399.00 and 415.00CAD.
Patch and Firmware Released for Sun Ray Products
For SRSS 4.2 and Sun Ray 3 Plus Clients
Sun Ray users have a new patch for Sun Ray Server Software (SRSS) 4.2 and new firmware for the Sun Ray product line's newest addition, the Sun Ray 3 Plus Client. The firmware is included in the patch, Sun Ray Core Services Patch-02, which means users can now deploy the Sun Ray 3 Plus clients via virtual private network (VPN). Oracle recently introduced the Sun Ray 3 Plus Client along with the latest release of Oracle Virtual Desktop Infrastructure software. These products add to Oracle’s desktop virtualization portfolio, which also includes Oracle Secure Global Desktop and Oracle VM VirtualBox.
Consolidation and Virtualization in the Mid-sized Enterprise
Oracle Sun IT Systems Deliver the Goods, Enable Significant Cost Reductions
Oracle's white paper "The New Economics of Midsize Enterprise Computing: Oracle’s Sun Systems Based on the Intel Xeon Processor 5500 Series" cites a recent CIO Insight magazine finding that notes increased IT spending in companies committed to cost cutting, a finding that appears to apply especially to the mid-sized enterprise. In that arena, with its typically smaller IT budgets, making purchases that offer the most efficiency and the best TCO is a critical exercise. This is where Oracle's Sun systems deliver solutions that lower total cost of ownership compared with previous generations of server platforms.
Sun Tape
Is Replacing Tape Storage Truly Cost Saving?
A Financial Methodology for Analyzing TCO of Tape Storage Solutions
An illustrative business case is presented in a tutorial on the framework and financial methodology for deciding whether its better to maintain the status quo tape storage solution or venture to a newly proposed tape storage solution. The Oracle white paper "Measuring the TCO of Tape Storage Solutions" analyzes each of the value drivers that contribute to the cost in each case, then an aggregate analysis is use to calculate the discounted total cost of ownership (TCO) savings.

    The newly merged Recommended and Sun Alert Patch Clusters are discussed in the blog on that subject by Gerry Haskins, who writes that the Recommended patch cluster contains the latest revision of Solaris OS patches that fix Sun Alert issues (i.e. Security, Data Corruption, or System Availability issues). These are the top-of-tree patches that fix Sun Alert issues. He adds that the Sun Alert patch cluster contains the minimum revision of Solaris OS patches that fix Sun Alert issues.
