Sun warms to open-source server software

By Stephen Shankland CNET News.com January 25, 2005, 6:41 PM PT

Even as Sun Microsystems took its first step to make its Solaris operating
system open-source software, the company said it's considering a similar
move with its server software product.

Sun is considering making its Java Enterprise System server software open-
source, John Loiacono, Sun's executive vice president of software, said in
a conference call with reporters Tuesday. "It's something we're looking at
closely right now. It's absolutely in our interest to go pursue that."

As expected, Sun launched its OpenSolaris.org Web site Tuesday, released
its Dynamic Tracing component of the upcoming Solaris 10 as open-source
software, and announced that more than 1,600 patents will be available for
unfettered use--a leapfrog over IBM, which two weeks ago offered use of 500
patents to open-source programmers.

"Sun is hoping to regain that position and image and reputation as being
the biggest friend of community development and open source," Chief
Executive Scott McNealy said. "With respect to Solaris and OpenSolaris,
we've done everything that was expected and even more."

Sun's open-source Solaris move is widely seen as a response to competitive
pressure from open-source Linux, which has attracted thousands of volunteer
and paid developers. For server software, IBM, Microsoft, BEA Systems and
others provide plenty of competitors for Sun's JES, which is used for tasks
such as hosting Web pages, managing e-mail, tracking passwords and running
Java business software.

Sun already has made aggressive moves to lure customers that have preferred
those rivals' products. Most notable is the per-employee pricing under
which Sun lets a customer use as much of the software as desired as long as
it pays Sun $100 per year for each employee in the organization. The
pricing can mean big savings over competing products.

Making JES open-source software "certainly would make sense given the way
they've been going," said Summit Strategies analyst Dwight Davis. "They've
been increasingly lowering the cost, to the point of free in some
instances, and offering compelling licensing terms."

So far, Sun's moves haven't damaged rivals' dominance, but Sun is
responding. Sun President Jonathan Schwartz said earlier this month that
the company is looking at selling the JES software for departments or other
employee subsets, not just for entire companies.

The departmental pricing "does address one of the major problems with the
corporationwide employee-based model," Davis said. "If you have 20,000
employees and 100 users, it doesn't make sense. But if all 100 are in the
finance department, under the new scheme, so much the better."

Don't expect an open-source JES anytime soon. Loiacono said Sun doesn't
want to overwhelm open-source programmers.

Software ascendant

Sun makes most of its revenue selling powerful networked computers called
servers, but since Schwartz was promoted from software chief to the No. 2
position last April, software has been gaining prominence at Sun.

Making Solaris open-source software is another part of that effort. Sun
hopes to restore its position among programmers "in dorm rooms and
laboratories," Loiacono said. Those programmers today often gravitate to
Linux.

"It's a way to get some attention, a way to potentially re-engage some
developers," said Illuminata analyst Gordon Haff. "This was a really clever
thing for Sun to do. It's hard to come up with a major downside to this."

There are practical reasons for OpenSolaris, Loiacono added. "One of the
stigmas we've had is we have been labeled as being closed and proprietary.
This is meant to take that on head-on," Loiacono said.

Microsoft makes billions of dollars each quarter with proprietary software,
but Sun wants to project a different image. "Large enterprises don't want
to get locked into a single vendor," McNealy said. Sun's general philosophy
of openness is aimed at reassuring those customers.

The first step
Sun released a Solaris component called Dynamic Tracing, or DTrace, that
lets experts find software bottlenecks. The 90,000 lines of DTrace code
will be joined by the remaining 9 million or 10 million lines of Solaris
code in the second quarter of 2004, Sun said.

"Now we're probably the No. 1 donator of lines of code of any organization
anywhere on the planet," McNealy said.

Sun will release OpenSolaris under the Community Development and
Distribution License, or CDDL, a variant of the Mozilla Public License. The
license lets anyone see, change and distribute the software, provided any
changes that are distributed are published.

Unlike the General Public License, or GPL, that governs Linux, software
governed by the CDDL may be mixed with proprietary software without
requiring that proprietary software to be released as open-source software.

And Sun elaborated on its promise not to attack when open-source
programmers use Solaris patents.

"By releasing OpenSolaris...under the CDDL, the open-source community will
immediately gain access to 1,600 active Sun patents for all aspects of
operating system technologies that encompass features ranging from kernel
technology and file systems to network management," Sun said in a
statement.

The patented technology may be freely used in Linux, Sun said. However,
intermingling Linux and OpenSolaris itself from one project to another
isn't likely because of incompatibilities in the CDDL and GPL. "It is
likely that files released under the CDDL will not be able to be combined
with files released under the GPL to create a larger program," Sun said
when it introduced the CDDL.

When Sun patent applications related to OpenSolaris are approved--and
several hundred are in the pipeline--those also will be released for free
use, Sun said. Sun will list the patents as the software using them is
opened.

Linux seller Red Hat and other open-source advocates have objected to
software patents. And a Hewlett-Packard executive has warned that Microsoft
planned to use its patents to attack open-source software.

昇陽所謂的開放 1600 項專利，看起來數字是比較大，但是要用到這些
專利技術，卻得掛在 OpenSolaris 名下才行...

感覺起來真是令人不太舒服，怎麼說都很怪。

SUN 感覺起來並不是真的要參與 OpenSource
之前已經有好幾個例子了
像是 之前 J2SE 的 JRL 授權
也被 Kaffe 的開發者批了一頓
