Links of interest for 27 Jan 2010 - 14 Feb 2010: eWEEK's Top 25 Technologies Of The Decade - Including Solaris 10 - "During the latter half of '00s, Sun Microsystems' Solaris 10 sat at the leading edge of operating system technologies, with unique capabilities that include Containers virtualisation, Dtrace system instrumentation and the ZFS file system. Solaris 10 also helped put a stamp of inevitability on the x86-64 architecture and on the open-source-as-a-platform licensing strategy." UK Govt Say "No Evidence" IE is Less Secure - Or more precisely, "There is no evidence that moving from the latest fully patched... Continue reading ►

Links of interest for 6 Jan 2010 - 26 Jan 2010: Internal Memo: Sun CEO Jon Schwartz to Staff - I didn't noticed this (I got the original), but these guys did: a little hidden message in Jon's memo. Note how it doesn't apply to the whole memo. Seems consistent with his efforts as a CEO: He started off well and then couldn't be bothered to finish what he started. EUROPA - Press Releases - Mergers: Commission clears Oracle's proposed acquisition of Sun Microsystems - And the official press release. Oracle wins unconditional EU approval for Sun buy - It's...

Did you know you can now upgrade both VxVM AND Solaris using Live Upgrade without reverting to underlying devices? I didn't, until today when I discovered a document on exactly this topic from Symantec: Upgrading VxVM and/or Solaris using Live Upgrade. From what I can see in this document, it appears VxVM now comes with it's own wrapper scripts for the standard Live Upgrade called vxlustart and vxlufinish respectively. BOTH commands are supplied on the VxVM 5.0 (and later media) and they both require and expect the native Live Upgrade pkgs and patches to be already applied to the system... Continue reading ►

Links of interest for 5 Nov 2009 - 2 Dec 2009: J is for JVM: Why the ‘J’ in JRuby? | Engine Yard Blog - A good explanation on why the guys behind jRuby like the J, aka Java Virtual Machine, part of JRuby. Interesting performance figures too when compared to the standard Ruby, especially considering people complain Java is slow. Senators press EU to speed its Oracle-Sun probe - I very much doubt this is going to have any effect on the EU regulators. They'll just perform the usual Gallic shrug and ignore the letter.

ZFS for MacOS X - One door closes, and thanks to Open Source, another opens. Apple cans ZFS project - It doesn't say much, but it speaks volumes.

Links of interest for 2 Sep 2009 - 24 Sep 2009: IBM Throws Out Microsoft Office - Welcome to the party IBM. Sun did this years ago. 99% of people don't use half the functionality in MS Office anyway. Linus calls Linux 'bloated and huge' - ... and it's suffered on average a 2% decrease in performance per release over the last 10 releases making a cumulative drop of 12%. How are the Linux advocates in the corporate world substantiating this drop in performance? Solaris customers certainly wouldn't accept it. Ellison: Sunacle is an IBM killer - `Ellison was adamant:... Continue reading ►

It's with great delight I read that the Solaris 10 Recommended and SunAlert patch clusters have been improved. Ed Clark has sat down and finally improved the install_cluster script, now called installcluster, and the cleaned up the directory structure. The whole build and verification process has been improved too. The improvements are quite significant and well detailed, so I'll just summarize the improvements: Continue reading ►

Ever wished you could get patchadd(1M) to give you the same verbose output pkgadd(1M) does with the -v option? Well believe it or not, you can, it's just not documented. I was perusing through the /usr/lib/patch/patchadd script on Solaris 10 and look what I found... function parse_args { [...] -g) PKGADD_DEBUG="yes"; shift;; [...] } This option isn't documented anywhere, however I do know modifying this script and manually setting this PKGADD_DEBUG variable to yes/true gives you output equivalent to "pkgadd -v" which the pkgadd(1M) man page explains... -v Trace all of the scripts that get executed by pkgadd,...

There is a very old bug in Solaris (now fixed in Nevada) in which the underlying permissions of a mount point affect the overlying mounted filesystem. The normal way to resolve this is to umount the filesystem, correct the permission and remount it. This is sometime easier said than done, for example, what if one of those filesystems is actually still in use, or even a critical OS filesystem like /var or /etc/mnttab. You don't really want to be umounting these whilst they're in use and the fix may involve booting from network or CD into single user mode. Well, there is an easier and relatively unknown method of correcting this... Continue reading ►
