Sun is about to open some Solaris source code new error correction tool

Sun will start opening the Solaris operating system as an open source software in US local time on Tuesday, and add new amplifier tool Dynamic Tracing. DTRACE is the most emphasis on the 10th edition of Solaris. Although this operating system is going to be available at the end of January, I want to see the complete original source code under the full OpenSolaris program, and I have to wait until the second quarter of 2005, the representative of Sun is expressed in Monday. Sun's OpenSolaris plans to be officially launched on Tuesday, and will open together with relevant legal details, OpenSolaris.org websites, and some new communities, "Advisory Board" - SUN I hope to make Linux before. At the same time as Linux, Solaris 10 will also be completely free, compared to the Red Hat, and ENTERPRISE Linux is charged. Sun was originally hoped to launch OpenSolaris programs in 2004, but because of the debate of authorization issues, it is delayed. "The length of time depends on the time of checking 500 to 10,000 lines of Solaris source code, and confirming that everything is appropriate." SUN Solaris Marketing Director Tom GOGUEN said in Monday. "We expect to put all things in the next quarter." GOGUEN said that Sun's representatives will accounted for 2 seats in the five advisers of OpenSolaris. Sun will compete with OpenSolaris's experimental plan (selected by other communities), as well as representatives of the vast open source community, sharing power, he said. Board members may assign in March. SUN-Solaris supporters and sellers will become an organization of OpenSolaris testing and certification. GOGUEN said. As for the source code donated to decide to join OpenSolaris via what mechanism, it is not clear. But GOGUEN said Sun is most likely a large mechanism for controlling the certification process. Sun also confirmed Monday will use the "Community Development and Difficulting License"; CDDL. This authorized prohibited programming designer is mixed with Linux software, but allows for exchange with other open source licenses. "We will do OpenSolaris in the CDDL authorization method, and in order to show out our attention, we also added DTRACE open source, let it under CDDL authorization." GOGUEN said. For Linux, the competitor has taken a complete attitude that is completely different from Sun. Such as HP and IBM - second only to Sun's UNIX Second and Third Master, I hug the Linux operating system before SUN. IBM and HP put Linux as a tool-like Power and Intel Itanium, which enhances its processor design. In the X86 server market forces, more powerful Dell, considering support Solaris during 1999. Sun said that the company spent more than 500 million US dollars to upgrade Solaris 9 to Solaris 10.goguen, pointed out that the company's Solaris program engineer exceeds 1,000. DTRACE can analyze when software is executed, finding and tracking those programs in requesting those programs. Compared to other detection techniques require special operating system versions, DTRACE support is already included in the core of the Solaris program.
"DTRACE is a feature in Solaris 10, which can dynamically assist the core, dynamically assisted applications, and make instant mixing and arranging." In a brief in November, the software programming is said. Cantrill said he uses DTRACE's prototype to diagnose the performance of the 2002 Sun server. "This is a machine with 3400 programs. But 6 cumbersome procedures dragged the entire system. When there is no DTRACE, there is no way to catch this bad problem at all." He said. DTRACE is also Sun's programming designer Alan Duboff favorite Solaris 10 function - Duboff is one of the "Secret Six" that prompted Sun to make X86 server version of Solaris decisions. Some software companies have expressed their worries for DTRACE to make customers find out the company's software's defects. While Duboff endorsed this view, he pointed out that Sun is also strictly supervised. "DTRACE is like a celestial camp." Duboff said, "There is no secret - even the same for Solaris." But DTRACE is currently the software that is currently the only open source code program designer. One of the biggest problems to release the original source code of the Solaris is that the more source code is required as much as possible. In the early days, Sun originally believed that bottlenecks may be the original UNIX source code authorization from AT & T, but in fact, it is necessary to obtain copyrights such as LSI Logic, Duboff. "Many source code does not have specific copyrights, to find out how much it takes for a lot of time." In addition to DTRACE, the new operating system features Containers (container): You can let a single server like multiple independent machines. Operation; preventive self-fixing, let the machine you find and avoid hardware problems; high-speed networks; more subtle authority control; also supports 64-bit X86 processors. The next update version of Solaris will use the ZFS file system, which can be more reliable and organized on the processing of information. Linux Application Environment (Code Janus) can make the Red Hat's Linux software can be executed on Solaris x86 without modification.
