Best linux distro for SAPGUI for Java based desktop client v2.0 (part 4)

I have already posted on my previous review here, here, and here. Now, I am going to post about Linux Mint, one of the best out of the box Ubuntu based Linux distro. I used to have this distro on my notebook before switching to OpenSuSE.

Linux Mint has great features according to their latest release notes such as :

mintMenu improvements

In Daryna, mintInstall and the Software Portal made it easy to install applications. In Elyssa mintMenu is making it easy to remove them. You don't need to open synaptic or to launch a terminal anymore, if you want to uninstall an application, simply right-click on it in the menu and select “Uninstall”.

mintUpdate improvements

MintUpdate was introduced in Daryna and quickly became one of the most popular tools on the Linux Mint desktop. It came to our attention that a lot of people weren't aware of how it worked internally (for instance, the difference between its user and admin runtime modes). For this reason we developed an information screen from which the active logs can be read, and the runtime mode and process id can be seen.

mintInstall improvements

.mint files can be quite complex as there's almost nothing you can do in a terminal that a .mint file can't do. In practice though, 99% of the .mint files present in the Software Portal consist in describing the installation of an application using APT. Most of these files describe the installation of only one package, and in most cases this package is present in the default repositories. In Daryna mintInstall used to backup the local sources.list, define its own, and then restore things as they were. This resulted in APT being told to update twice. In Elyssa, the mintInstall client checks if the packages are present within the repositories defined on your system, if they are the client gives you the choice of whether you want to use your sources.list ("local repositories") or the one coming with the file ("default repositories"). The default selection is "local" and as it basically saves 2 APT updates the installation of the application via mintInstall is consequently much faster.

Improvements in other tools

The network autobrowsing feature was removed from mintDesktop as it wasn't mature enough to be part of this LTS release. Gnome 2.22 introduced its own compositing manager which can now be activated/deactivated from mintDesktop. Mintupload's email feature was removed and replaced with a "Copy" button, which simply copies the shared URL to the buffer.

Desktop improvements

Gnome-Do doesn't just come installed by default in Elyssa, it's configured to run in the background. Press SUPER+SPACE and it should appear. From there you can quickly launch an application or use any of the advanced features provided by this tool.

Performance improvements

MintUpdate was refactored and its memory usage was drastically reduced. On some systems the amount of RAM used by mintUpdate after a few days went from 100MB to 6MB.

Mozilla also greatly improved the memory usage in Firefox between version 2 and 3 (Read more). Elyssa comes with kernel version 2.6.24 which features a brand new scheduler called CFS (Completely Fair Scheduler, Read more). The kernel scheduler is responsible for the CPU time allocated to each process. With CFS the rules have changed. Without proper benchmarks it's hard to actually tell the consequences of this change but the difference in behavior is quite noticeable from a user's point of view. Some tasks seem slower, but overall the system feels much snappier. Elyssa comes with Gnome version 2.22 which features a new virtual filesystem layer called GVFS. Although the improvements over the old GNOME-VFS system are geared towards robustness and additional capabilities more than performance the Nautilus file browser seems more responsive and the progress feedback given while moving sets of files actually gives the impression of smoother, almost faster, operations. Linux Mint is growing and acquired a second dedicated server. The Linux Mint repositories (starting from Elyssa) are now hosted on a distinct server so updating and installing mint packages is now much faster.

Better Look and feel

All Mint tools were reviewed and changes were made for their graphical interface to be more compliant with the Gnome Human Interface Guidelines. The default set of GTK widgets used in Daryna was called MurrinaIndustrialSM. Subtle changes and refinements were made to it. Sliders now use the Clearlooks engine, scrollbars are now white and come with handles, columns headers were made glossy, dotted lines were added in tables and the roundness level was decreased slightly. Overall it looks pretty similar to Daryna and you might not notice the difference until you actually look into it. It's all about attention to details though and we're quite happy with the improvements we made on this. The colors are also configurable now so that's probably great news for people looking for an easy way to make Linux Mint a little greener.

And some other great features.

Linux Mint powered itself with SUN JRE 1.6 out of the box, restricted audio and video codec, etc. You can directly installed SAPGUI for Java here without worrying about JRE.

I am still highly recommend this distro especially for Linux newbie and label this distro as one of SAPGUI ready Linux distro. This distro is absoultely free and please consider to donate to help Clement Lefebvre maintain this distro. Happy Mint-ing !!

Best linux distro for SAPGUI for Java based desktop client v2.0 (part 3)


Previously I have posted about linux distro here and here, now I am going to continue my review about OpenSuSE 11.0 as one of linux distro which is also supported by SAPGUI for Java.

Starting on this release, finally OpenSuSE - as other linux distro too - has included SUN Java (Thanks to SUN which had been released Java under Open Source license). In fact, OpenSuSE has done great job on this release. They said this is one of the best OpenSuSE release ever. That's make me so happy. I am SuSE fans...

According to OpenSuSE website (http://www.opensuse.org) on their release notes :

"The openSUSE Project is proud to announce the release of openSUSE 11.0 - everything you need to get started with Linux on the desktop and on the server. Promoting the use of Linux everywhere, the openSUSE Project provides free, easy access to the world’s most usable Linux distribution, openSUSE. The 11.0 release of openSUSE includes more than 200 new features specific to openSUSE, a redesigned installer that makes openSUSE even easier to install, faster package management thanks to major updates in the ZYpp stack, and KDE 4, GNOME 2.22, Compiz Fusion, and much more."

Also check this out for latest Compiz feature. Very nice. I like it.

OpenSuSE also come with SAMBA which is mandatory for running as SAPGUI ready desktop client.

But just as your consideration before choosing OpenSuSE, your computer specification must have minimumly 512 MB memory. But I recommend you to have 1 GB memory for minimum requirement. Currently, I am using OpenSuSE 11.0 on my Acer notebook

Happy migrating !!

Best linux distro for SAPGUI for Java based desktop client v2.0 (part 2)

As previous stated on my posting before, I still recommended Vector Linux with newer version 5.9.1 SOHO Edition. From Vector Linux website release notes, they mentioned this :

"We have released SOHO-5.9.1-DELUXE! To complement it we have released a standard version, free for download!!

The 5.9.1 release is a maintenance bug fix release for the previous SOHO 5.9 and includes 52 updates to the core system. You will also find Firefox-3.0.1, opera-9.52, pidgin-2.5.1, sane-1.0.19 and a host of others. The kernel has been upgraded to 2.6.25.7 for better driver support in both sound and wifi.

After long consideration we determined that this was just to darned good and we wanted everyone to see just how good this is. We are confident that after trying the free version you will want to come back and purchase the DELUXE version. In addition to an expanded first disk, the deluxe version comes with a second multimedia CD which contains loads of extras, including more applications, functionality and original artwork.

The default desktop is KDE 3.5.9. More than just amazing eye candy, KDE's extensive collection of graphical tools makes it easy to use for non-technical users. Still, the speedy Fluxbox is available for power users. The included office suite, image manipulation and desktop publishing software will quickly put Small Office/Home Office users to work. Since regular breaks have been shown to increase productivity, you will also find a nice collection of games. For the server role, samba, apache, mysql and php are included.

For those who have purchased the previous 5.9 SOHO release, we are offering the updated 5.9.1 release as a free download from our high speed host SQI. All you need to do is reply to the original email you received with the purchase and request download instructions. Any other requests concerning the purchase of 5.9 and the 5.9.1 update can be directed to support@vectorlinux.com
"

From my own point of view, Vector Linux has given us great distro, even if we have just had its CD without any software supplement. They have given us SAMBA server, Secure Shell (SSH) server, CUPS, The latest Open Office version, and nice modified and boosted KDE desktop environment.

We need SAMBA server so desktop which has printers attached can print from SAP. It will collaborate with Windows based SAP Print Server (contact me if you want to get paid support). Also, we need SSH server on linux client to support end user without bothering while they are working. Of course we need CUPS since it is default printer daemon on Linux. Open Office has become default office application on Linux and even on several countries has decided to use OpenOffice type for their default document processor. Nice looking GUI would help user to migrate from Windows.
Vector Linux also, by default, has included SUN JRE so you don't have to download them separately. All you need is install this distro and run it.

So personally, I still highly recommended Vector Linux based on its stability, light, fast, and compact size. Hey...It's only one CD and you'll get everything.
