DTRACE (Dynamic Tracing)
Chinese is called dynamic tracking system, is a tool for DEBUG and performance tuning. The traditional UNIX / Linux system provides NetStat, Vmstat, Iostat, Systat, FSTAT, and FSTAT, but lacks Per Process, Per User's ability, DTRACE makes this through more than 25,000 data monitoring points in the kernel. Maybe. DTRACE also allows programmers to view interactive activities between their applications and kernels through the control flow between the user / core boundaries. Coupled with DTRACE easy-to-learn D language, the build custom program is used to dynamically track the system, and provide an instant, concise answer to any issue of operating system and user programs. Interested words to see the following DTRACE instance, enjoy the power of it:

2. N1 Grid Containor Chinese is called N1 grid container, allowing a Solaris system to divide multiple partitions, each running Solaris instances independently. I believe that everyone has earned IBM hardware partitioning technology. The N1 Grid Containor is a pure software implementation. The Solaris system of multiple partitions divided on a machine, which is isolated from each other, as if you have multiple machines, so that your hardware is most efficient. It is more likely to understand it by VMware.
3. ZFS massive log file system has a capacity equivalent to 16 billion times the existing file system. Supports 128-bit addressing space to support zbyte (1G GB!) File system. ZFS can easily manage cross-regional volumes, and automatically check errors when reading and writing data. Support logical volume management (LVM), the size of logical volumes can be considered unlimited, supporting RAID's Mirror and Strip-like features. That is, there is ZFS, Veritas similar volume management is unneed.
4. Java Desktop System Very Cool's desktop is not bad compared to Linux, and the user who has used Linux version of JDS will be surprised. Solaris 10 is also! The following is a screenshot of JDS:
5. Frame-style system service management is familiar with UNIX and Linux users know that the launch of the system service is based on the scripts under RC * .D, all services are sequential, regardless of the dependencies. The service that the system has started can only use the PS command. Solaris 10 does not use the script of RC * .D to manage the system service management, but put all system service packages under a Ramework, the administrator can check or initiate the service to manage the service through special commands. At startup, the dependent relationship is dependent on the service, and the parallel start service (this is probably learning Windows).
6. Run Linux binary directly
Linux's binary can run directly on Solaris X86. Never have to use the Solaris desktop application less! Sun explicitly indicates that it can be fully universal with Red Hat Enterprise Linux 3, but there is no Linux issued for other companies such as Novell SUSE. 7. The launch of the new 64-bit Solaris operating system AMD 64-bit CPU Opteron has undoubtedly sentenced the death penalty of the Intel Anteng processor. Sun has launched a 1st and 2 channels, and is about to launch 4 Optern processor-based servers. 32-bit Solaris can be running on Optern, 64-bit Solaris is about to be available, 64-bit computing power will be fully utilized. I hope Sun can grasp this opportunity and occupy a place in the X86 server market.
8. Predictive Self Healing (predictive self-healing)
The technology creates a mirror buffer on the server. When the server detects that a part of the CPU, Memory, and I / O bus may fail, switch to another, avoid operating system crash or loss data. . This technology probably requires hardware support to implement, so it is only possible to apply on the high-end SPARC server in Sun, and X86 is not supported.
9. xorg
The famous XORG, I believe many people are not strange, Solaris will integrate xorg, XSUN is no longer your unique choice. At that time, Solaris will support more graphics cards, and the beautiful JDS started on x86 will be as easy as Linux.
10. Driver
When the Solaris 10 releases, hundreds of new hardware from Sun and third-party IHV will be added to the HCL (hardware compatible list), which will be easier to install Solaris on the X86 system. Access Solaris OS HCL, you know if your hardware is available on Solaris: www.sun.com/bigadmin/hcl
In addition, it is worth mentioning that Sun re-implements all TCP / IP network protocol stacks, making Solaris's TCP / IP performance greatly optimized and improved.
The above is the latest change in Solaris, you can get all the latest messages from Sun's Blog (http://blog.sun.com). Or, download the latest Solaris 10 version for free to the SUN website, experience these upstures. Of course, some features may be under development, I want to get the latest version at any time to download Solaris Express version: http://wwws.sun.com/software/solaist/solaris-express/get.html
