Oracle: Unbreak my Linux Heart

Where I had great difficulties trying to get OMSA to install let alone work in Oracle's Enterprise Linux 4 (u5 and above), I am happy to report that I got it working out-of-the-box after an install of my custom 5u3 image, following the instructions on the OMSA Repository Wiki . A simple http proxy setting, the wget boot strap line to configure yum and the dependencies and I was in business! Excellent work, Dell!

On the Dell PowerEdge mailing list, someone complained in details about the performance of the PERC6 RAID controller that dell uses by default in all its servers. The guy makes a compelling case with ~30-50 Mbps performance to local disks where a comparable Arcea card reaches ~300-400 Mbps! Anyway, long story short, he has detailed instructions and photos documenting his swap online.

Oracle's announced Oracle VM 2.2 , their latest Xen-based general purpose virtualization technology platform for their Red Hat-based Enterprise Linux version (OEL). Coupled with a new ocfs2 version and a few enhancements, you get ThinProvisioning for VMs and snapshots on cluster-aware files systems. That means they can span across data centers or locations. Update: wording changed as suggested by comment Update2: Oracle VM 2.2 CLI available too

Subversion v1.6.6 has been released. Most relevant changes (IMHO): User-visible changes: * fix crash during 'svn update' (r39673) * respect Apache's ServerSignature directive (r40008, -21, -31) * fix a crash in 'svn rm --force' (r37953) * handle tree conflicts involving replacements (issue #3486) * improve merge performance with implicit subtree mergeinfo (issue #3443) * make file externals work for binary files (issue #3368) * improve "tree conflict already exists" error message (r38872)

If you write code on a regular basis (programs, scripts, tools or installers), chances are you will run into a case where you need to compare 2 or more versions of the same file and find out what their differences are. Diffuse may just save your day at that time!
