Solaris 10 is about to be released. What functions are included in the new version worth looking forward?

1. dtrace (Dynamic Tracing)

It is called a dynamic tracing system and is a debug and Performance Tuning tool.
Traditional Unix/Linux tools such as netstat, vmstat, iostat, timed at, and fstat provide some system information, but lack the ability of per process and per user, dtrace makes this possible by over 25,000 data monitoring points in the kernel.
Dtrace also allows programmers to view interactions between their applications and kernels by observing the control flow between user/kernel boundaries. Coupled with the easy-to-learn language D of dtrace, it is possible to build custom programs to dynamically track the system and provide immediate and concise answers to any questions about the operating system and user programs.
If you are interested, let's take a look at the following dtrace instance to see its power:

2. N1 Grid containor

The N1 Grid container allows multiple partitions in a Solaris system, each of which runs the Solaris instance independently.
I believe you have heard about IBM's hardware partitioning technology. N1 Grid containor is purely software implementation.
Solaris systems with multiple partitions divided on one machine are isolated from each other, as if they have multiple machines at the same time, making the most effective use of hardware.
It is easier to understand VMware.
3. ZFS
A massive log file system has a capacity of 16 billion times that of an existing file system.
Supports 128-bit addressing space and zbyte level (1 GB !) File System. Zfs allows you to easily manage cross-zone volumes and automatically validate errors when reading and writing data.
Logical volume Management (LVM) is supported. The size of logical volume can be considered unlimited. The raid mirror and strip functions are supported.
That is to say, with ZFS, similar volume Management of Veritas is not required.

4. Java Desktop System
Very cool desktop, not inferior to Linux, users who have used Linux JDS will be surprised to find that Solaris 10 is also available!
Below is the JDS:

5. Framed System Service Management
Users familiar with Unix and Linux know that the startup of system services depends on the scripts under rc *. D. All services are started sequentially regardless of their dependencies. You can only use the ps command to view the services started by the system.
Solaris 10 no longer uses rc *. d. The script is used to manage system services. Instead, all system services are encapsulated in a type of ramework. The administrator can view or start or stop the services by using special commands to manage the services in a unified manner. during startup, the service will be started in parallel based on the dependency between services (this is probably to learn about windows ).

6. Run the Linux binary program directly.

Linux binary programs can run directly on Solaris x86. There is no need to worry about less Solaris desktop applications!
Sun clearly states that it can be fully used in the same way as Red Hat Enterprise Linux 3, but there is no release description for Novell's Suse and other enterprises such as Linux.

7. New 64-bit Solaris operating system

The launch of AMD's 64-bit CPU opteron has undoubtedly been sentenced to the death penalty of Intel's Apsara processor.
Sun has released 1-and 2-ways, and will launch 4-way optern-based servers. 32-bit Solaris can run on optern, and 64-bit Solaris will be available soon, the 64-bit computing capability will be fully utilized.
We hope sun can seize this opportunity and have a place in the X86 server market.

8. predictive self healing (predictive self-healing)

This technology creates a memory image buffer on the server. When the server detects that a part of the CPU, memory, and I/O bus may fail, it automatically switches to another image, avoid operating system crashes or data loss.
This technology requires hardware support, so it can only be applied to Sun's high-end iSCSI server, but not x86.

9. Xorg

We believe that many people are familiar with the well-known Xorg. Solaris will be integrated with Xorg, and xsun is no longer your only choice.
At that time, Solaris will support more video cards, and enabling beautiful JDS on x86 will be as easy as Linux.

10. Driver

When Solaris 10 is released, hundreds of new hardware types from sun and third-party ihv will be appended to the HCl (hardware compatibility list), making it easier to install Solaris on x86 systems.
Access Solaris OS HCl to check whether your hardware is available on Solaris:

In addition, it is worth mentioning that sun has re-implemented all the TCP/IP network protocol stacks, greatly improving the TCP/IP performance of Solaris.

The above is the latest change to Solaris worth looking forward to and you can get all the latest news from Sun's blog (http://blog.sun.com. Alternatively, download the latest Solaris 10 version from the sun website for free and try these latest features. Of course, some features may be under development.
