Take A Look At Solaris 10
SilentBob4 writes "There haven't been many reviews of the recent Solaris 10 release from Sun Microsytems, and even those which are available are thin at best... until now. Mad Penguin, normally a Linux-only site, has release the most comprehensive and well-written review of the OS to date."

Actually, there are many (mostly-legacy) applications that will ONLY run on the "older" Unicies.
I worked for a number of years doing SysAdmin/Infrastructure-Architectural work for various global banks. The majority of the niche applications used to provide complex financial services are STILL not ported to "modern" unix-like OS's.
As an example, DST International's (http://www.dstinternational.com) HiPortfolio product will only run on IBM's AIX and Sun's Solaris as it's Unix OS platform. The reason for this is the product is so damned old and ingrained into that specific industry, the company can afford to ignore their customers demands and not re-invest potential profit in expensive porting exercises... You can get away with murder by holding a monopoly on most of the large Asset-Management businesses.
If a bunch of clever programmers got together and wrote some clean, horizontally-scaling, easily intergrated applications to destroy the hold of these monopolistic "niche" software products, they could really make some money (and the world would be better off with one less monopoly market).

Sun Microsystems has recently released Solaris 10. It is currently free, as in beer, and most of it is promised to be released under an OSI approved license in the second quarter of 2005. Most everyone reading this probably knows all of that. The release and subsequent open sourcing of Solaris 10 has caused quite an uproar in the Open Source community and the IT industry as a whole. Linux advocates have been fighting Solaris advocates on forums across the Internet. The zealotry and misrepresentation from both sides has been really quite impressive. However, I am a BSD user. I am not on either side and will do my best to allow neither zealotry nor misrepresentation into this review.
Please continue reading after you have stopped laughing.
All political issues aside, Solaris 10 is a very impressive OS. It has some features no other operating system can claim and some that are not necessarily new, but have been implemented in an excellent way. This is not to say it is perfect. There are definitely things I dislike and areas that seem quite unpolished.
One of those aforementioned unpolished areas is the installation routine. It can be assumed that Solaris will not be installed by a novice. Even so, the Solaris install is painful and brings with it memories of Windows 2000 installs of old. This is not because its difficult, it is not. The installation is simply unwieldy. My main complaints are the following:
* You must partition, install a small base system and reboot to finish the install. I expect an OS to be installable without a reboot.
* For the first section of the install there is a web browser in the background, but for unknown reasons there is no browser in the second section.
* You have to switch CD's during the install, which is fine, but you can't just switch and walk away. You have to wait for it to read the CD and display another screen and then press next. There is probably a reason for this, but I just find it annoying.
Issues like these make the installation routine seem unfinished and just don't fit with the overall quality of the OS.
Upon booting Solaris for the first time, you are greeted by dtlogin. This is the default graphical login manager for Solaris and plainly has CDE roots. At this point, there is a drop-down menu in which you can choose to go back to a console login or choose which wm/dm to enter, both CDE and JDS3 are options. I am sure CDE has many great features and I know that some people love it. However, I am not one of them. JDS3 on the other hand is a nicely polished GNOME desktop. The theme and general feel is much improved over Sun's earlier versions. Nothing is very remarkable about JDS3, except network browsing. I have never seen any GNOME desktop do as well with windows and NIX network browsing.
There are things I dislike about JDS. As a media player, Sun has chosen the "Java Media Player." This program has no redeeming factors. XMMS or Rhythmbox would be much better choices. They also tapped Mozilla to be the web browser, not Firefox. With FF gaining more and more attention, this choice makes very little sense to me. However, those are my only complaints about JDS3 and they are small ones.
Nobody is considering Solaris 10 because of JDS3 or its installation routine. They are looking at it because of new features like DTrace, Zones and the new Service Management Framework. Indeed, it has been quite awhile since we have seen a release of any OS with as many large features as Solaris 10.
DTrace
One of the main new features in Solaris 10 is DTrace, a dynamic instrumentation system. DTrace consists of a scripting language, named D (not to be confused with the fledgling D Programming Language), and loadable kernel modules named "providers." When called upon, these "providers" track and report system information. DTrace has several features that separate it from other similar systems:
* It is dynamic. DTrace has no effect on system performance when not in use. Only those providers t
Ah, Solaris 10, the rootkit writers friend.

The reviewer miss in his zones explanation the part about Resource Manager. This is simply a zSeries like WorkLoad Manager tool. It allows to assign processing power per process and per zone, and also physical and virtual memory per user. Simply put, if you have 3 process running, you can assign each process 1/3rd of the processing power of the system, 1/3rd of the physical memory to each process (so no process force a page-out for all the others), and the same amount of virtual memory as the hole system memory (as long as the working set for each process fits in) to avoid memory leak problems.
Other point is that the installer have a bug and although it asks if you want the 1st CD to auto pop-up, it wont work, you need to take it out before it starts the installation all over again. Some bouilds have a message reporting this error (instead of fixing it...).
Binary compatibility is withit the ABI for the same platform (obviously, you can't move a SPARC binary to an Opteron box). The good part is that source files will written using the standar ABI will recompily straight.
The main-point with any other OS than Linux is that rigth-now companies seems more likely to die than the hole Linux movement (or however you want to call it).
