I’m back with Fedora 11
I’m back with Fedora 11
La derniere version de Fedora est sortie le 8 novembre. Originalité de cette version, en plus de la version “full” traditionnelle, elle se présente sous trois angles différents:
- Fedora Games Spin : un Live DVD rempli de jeux 2D et 3D (Nexuiz, Quake, Freeciv, Nethack …)
- Fedora Developer Spin : un Live DVD qui contient seulement des programmes de développement (Eclipse, Anjuta, git, cvs, lynx, emacs, éditeur hexadécimal … )
- Fedora Electronics Lab : cette version est destinée aux personnes qui souhaitent utiliser des programmes de simulation de systèmes électroniques
La petite particularite qui m’interesse personnellement et l’amalioration de la prise en charge du wifi. NetworkManager 0.7 a été réécrit pour gagner en stabilité et en flexibilité. Celui-ci devrait assurer une plus grande rapidité de connexion, une meilleure intégration grâce à l’API Dbus et au WPA pour le wifi. (il était temps)
Oracle is going to launch today Oracle Database 11g
On Oracle website you can join a live webcast about this new version. it will be at 10 a.m. ET
We had to wait 4 long years to have these 482 new features with data compression for example or hot patching (that sounds great) or new RAC possibilities:
Oracle continues to enhanced Real Application Clusters in Oracle11g and we see some exciting new features in RAC manageability and enhanced performance:
Oracle 11g RAC parallel upgrades - Oracle 11g promises to have a rolling upgrade features whereby RAC database can be upgraded without any downtime. Ellison first promised this feature in 2002, and it is a very challenging and complex 11g new feature.
Oracle RAC load balancing advisor - Starting in 10gr2 we see a RAC load balancing advisor utility. Oracle says that the 11g RAC load balancing advisor is only available with clients which use .NET, ODBC, or the Oracle Call Interface (OCI).
ADDM for RAC – Oracle will incorporate RAC into the automatic database diagnostic monitor, for cross-node advisories.
Optimized RAC cache fusion protocols - moves on from the general cache fusion protocols in 10g to deal with specific scenarios where the protocols could be further optimized. Source: Mark Rittman
Oracle 11g RAC Grid provisioning - The Oracle grid control provisioning pack allows you to “blow-out” a RAC node without the time-consuming install, using a pre-installed “footprint”. Oracle 11g OEM has have easy server blade installs where a binary footprint is tar’ed to the server blade and configured, without a cumbersome install process.
Hot patching - Zero downtime patch application.
Data Guard - Standby snapshot – The new standby snapshot feature allows you to encapsulate a snapshot for regression testing. You can collect a standby snapshot and move it into your QA database, ensuring that your regression test uses real production data.
Quick Fault Resolution - Automatic capture of diagnostics (dumps) for a fault.

It’s now official, Oracle has announced the release of Oracle 11g on 11th July 2007.
Since last October and the OpenWorld conference, Oracle was anouncing this new version. A lots of new features will be avalaible in this 11g version. That will be detailed on a future post.
Of course i’m sure you notice that 11g will be launched 11 july (and “g” is the 7th letter of the alphabet and july the 7th month of the year) Oracle 11g should be a lucky version even if it will not be launched th 7th July (07/07/07)
The new release of Fedora is avalaible: “Fedora 7″.
Here are the new features:
Please remember also to use “Pungi” to create your own linux distribution
Download it and test it : FedoraProject.org.
Red Hat has released the new version of it’s operating system RHEL 5 (Red Hat Enterprise Linux). RHEL 5 implements a totally integrated Xen-based server and storage virtualization solution, by combining server virtualization with Red Hat’s clustering support. In addition, RHEL 5 comes with a virtualization manager that should make installing and administering Xen virtual machines much easier.
Performance and scalability improvement have been done with this new version. The kernel version is now 2.6.18 (previously it was 2.6.9) Security with RHEL 5′s SELinux (security enhanced Linux) was also improved and should be easier to use.
Another big evolution is the introduction of yum. You should be able to have a yum repository. Everything will be based on yum (the system-config-packages, the RHEL update,…)
In the meanwhile, you may have already tested the RHEL 4 update 5 (which is the first update for RHEL 4 to include Xen paravitualized kernels). It was released last week, and the main evolve is the integration of XEN. Xen is the open source virtualization effort that Red Hat has already included in its Fedora community Linux releases (with Fedora Core 6) and is part of Novell’s SUSE Linux Enterprise 10 release as well, for many months now.
