Reviews of Sun’s virtualization product offerings

April 25, 2008

1. Sun “innotek” VirtualBox — darpan.et.work, 4/21
Darpan Dinker posted about his experience using VirtualBox running Solaris Express Developer Edition. Darpan liked the fact that VirtualBox came with an Ubuntu download option and a common user manual.

4. Run IE6, IE7 and IE8 on your Mac — The MozMonkey Blog, 4/20
Jeremy Gillick wrote about running different versions of IE on his Mac by using VMware and VirtualBox software. He found that it was easiest to use VMware Fusion, but liked the fact that VirtualBox was free and available for most operating systems.

5. Sun xVM Ops Center — ZDNet, 4/18
Dan Kusnetzky discusses Sun’s xVM Ops Center, and his overall impression is that this is a powerful tool that will be a good foundation for users of Sun’s Solaris, Red Hat’s REL and SUSE’s SLES operating environments. He comments that as one would expect for a version 1 product, it has its rough edges but strong promise for the future.

This Week’s NetBeans Developer Reviews

April 24, 2008

1. Netbeans – Stairway To Maven — Adam Bien’s Weblog, 4/18
Adam Bien found that his experience giving Maven support in Eclipse a try was not so bad, but he preferred NetBeans by far. He found that the native support for Maven in NetBeans gives it a huge edge over Eclipse, as NetBeans just uses Maven to build the artifact instead of the internal build system.

Vando Batista wrote that he had to use the tkSVN (tkCVS) tool due to the limitations of the NetBeans SVN client. Vando explained that using the NetBeans 6.1 Beta, it is not possible to put a UML (model) project into Subversion. The solution is to use an auxiliary SVN GUI client (tkSVN in his case) to maintain all the UML diagrams files synchronously related to the code project.

6. Flex and OpenLaszlo in NetBeans 6.1 Beta — Dustin’s Software Development Cogitations and Speculations, 4/17
Dustin Marx noted that the NetBeans 6.1 beta IDE has added tremendous support for JavaScript and the Spring Framework, but would like to see support added for Flex and OpenLaszlo. Dustin also demonstrates how to associate OpenLaszlo’s LZX files and Flex’s MXML files with XML in the NetBeans 6.1 beta.

7. Ajax Autocomplete not yet supported in NetBeans Visual Web — David Heffelfinger’s Notes, 4/16
David Heffelfinger ran into problems installing Ajax autocomplete, even though the version of Woodstock included with NetBeans 6.1 RC1 supported autocomplete. He discovered that NetBeans does not have the required versions of some libraries to support autocomplete. He expressed hope that this will be resolved in the final release of NetBeans 6.1.

OpenSolaris reviews of the week

April 18, 2008

1. BeleniX 0.7 OpenSolaris Desktop — Phoronix, 4/16
Michael Larabel finds that BeleniX 0.7 has many of the Project Indiana features, but its LiveCD uses Xfce and KDE as the two desktop environments of choice compared to Indiana’s GNOME. BeleniX is also continuing to use SVR4 packaging instead of IPS. In conclusion, Michael says that having tried out BeleniX 0.7 for a bit now, he is pleased with the continued innovation the BeleniX developers are doing on top of the OpenSolaris stack.

3. Nexenta, BeleniX, Solaris 10: Fun with UNIX — JamesTheBard, 4/12
The blogger installed Solaris, BeliniX and Nexenta on his desktop using VMWare to take a closer look at Solaris, its derivatives and some of its features such as DTrace and ZFS. He gave Solaris 10 a score of 6/10 saying that it was easy to install but that updating was complicated. He thought the other distributions did not perform as well, concluding: "There aren’t really that many options out there if you want to try out something Solar-ish other than Solaris."

4. Why ZFS rocks — Bits on Bytes, 4/11
Christopher Gibbs wrote that "ZFS rocks" because the file system in Solaris prevented any data loss when his server’s hard drive failed and his spare hard drive wasn’t configured properly: "ZFS let me add my spare and replace my failed drive with it — all while my data stayed up. You can even see it scrubbing data over to the spare!"

Customer of the Week: LG Micron

April 15, 2008

With help from Sun Professional Services, leading Korean manufacturer LG Micron successfully deployed a six-node high-availability cluster of servers using high-performance Sun UltraSPARC IV+ processors. The Sun Cluster solution provides 24×7 business continuity for the Oracle database and ERP applications.

Sun delivered the solution using LG Micron’s existing IT assets and helped it maximize operational productivity. The solution is the first six-node cluster implementation in Asia and the first deployment in South Korea to use Solaris Volume Manager to mirror data to a remote site to enhance disaster recovery.

Heechang Park, CFO/CIO of LG Micron, commented: “We tried to provide non-stop IT service by leveraging old systems in order to minimize IT investment and established a cluster system in order to minimize any possible risks. Moreover, LG Micron established business continuity from a server/storage HA project. Previously, we assume that we wasted 1 million a year at the production line due to system failures and service stops. However, our IT system now provides non-stop service through standby-system configuration, and we secured our ROI for this project.

Check out the details here.
