Sun acquisition by Oracle
The acquisition of Sun Microsystems by Oracle Corporation was completed on January 27, 2010. Significantly, Oracle, previously only a software vendor, now owned both hardware and software product lines from Sun (e.g. SPARC Enterprise and Java, respectively).
A major issue of the purchase was the fact that Sun was a major competitor to Oracle, raising many concerns among antitrust regulators, open source advocates, customers, and employees.[not in citation given] The EU Commission delayed the acquisition for several months over concerns of Oracle's plans for MySQL, Sun's competitor to the Oracle Database. The commission finally approved the takeover, apparently pressured by the U.S. to do so, according to a Wikileaks cable released in September 2011.
In late 2008, Sun was approached by IBM to discuss a possible merger. At about the same time, Sun also began discussions with another company, widely rumored but unconfirmed to be Hewlett Packard, about a potential acquisition. By March 2009, talks had stalled between Sun and both IBM and the other potential suitor.
On April 20, 2009, Sun and Oracle Corporation announced that they had entered into a definitive agreement under which Oracle would acquire Sun for $9.50 a share in cash. Net of Sun's cash and debt, this amounts to a $5.6 billion offer from Oracle. Sun's shareholders voted to approve the proposal on July 16, 2009, although the deal was still subject to regulatory approvals. Terms of the agreement between Oracle and Sun included dependencies on the antitrust laws of "the United States and Canada, European Union, China, Israel, Switzerland, Russia, Australia, Turkey, Korea, Japan, Mexico and South Africa".
On September 3, 2009, the European Commission announced that it would not immediately approve the deal, but would instead perform a second round of investigation, focusing on the implications of Oracle's control of MySQL (acquired by Sun in 2008).
On October 20, 2009, Sun filed with the U.S. Securities and Exchange Commission (SEC) its intention to cut 3,000 jobs globally over next 12 months, citing losses caused by delays in the acquisition process.
On November 6, in its 10-Q filing for the 1st quarter of the 2010 fiscal year, Sun announced 25% total revenue decrease, compared to the 1st quarter of the previous year, due to "economic downturn, the uncertainty associated with our proposed acquisition by Oracle, increased competition and delays in customer purchasing decisions".
On January 27, 2010, Oracle announced that it had completed its acquisition of Sun Microsystems, making Sun a wholly owned subsidiary of Oracle.
On January 30, 2010, the Official Website of Sun Microsystems www.sun.com was closed.
Several notable engineers resigned following the acquisition, including James Gosling, the creator of Java (resigned April 2010); Tim Bray, the creator of XML (resigned February 2010); and Bryan Cantrill, the co-creator of DTrace (resigned July 2010).
Most of Sun's executive management team, including CEO Jonathan Schwartz, resigned immediately after the acquisition was complete. John Fowler, Executive VP of Sun's systems group, remained at Oracle as Executive Vice President of Hardware Engineering.
Then in August 2010, leaked documents indicated that Oracle would end releases of OpenSolaris in May 2010. In addition, it would no longer release the developing Solaris source code during development. Instead it would only publish it after each new version of Solaris is released. Since Oracle was no longer supporting all the development of an open version of Solaris, the OpenSolaris Governing Board disbanded, ending the project. Independent development continues with the Illumos fork.
MySQL petition and forks
In response, several forks were made with the intent to ensure the future success of MySQL despite being purchased by its biggest competitor. These include Drizzle and MariaDB. Monty Widenius, one of the founders of MySQL, also started a petition asking that MySQL either be divested to a third party, or have its licensing changed to be less restrictive than the previous GPL terms it operated under prior to and during its ownership by Sun.
Java Android lawsuit
Oracle filed a patent infringement lawsuit against Google over its use of Java in the Android platform. Android apps run in the Dalvik Java virtual machine. The apps are written in Java but are compiled into Dalvik's custom bytecode format which is incompatible with standard Java runtime environments. Google thus avoided licensing fees associated with J2ME, the mobile version of Java. However, aspects of the Dalvik system are very similar to the Java technology patented by Sun and now Oracle.
The court found that Oracle's primary copyright claim, based on the Java Application Programming Interface (API), failed because the portions Google reused were not copyrightable. Google was found liable for a small amount of literal code copying. Oracle will be limited to statutory damages for these claims. The jury found that Google did not infringe Oracle's patents. Oracle has said they will appeal.
Regardless of the legal merits, commentators have questioned the wisdom of the lawsuit over Android, a platform which has reinvigorated the Java community. In addition, it gave another worrying signal to open source community members about Oracle's stewardship of open technology.
Apache Software Foundation resignations
The Apache Software Foundation has resigned its seat on the Java SE/EE Executive Committee due to Oracle’s refusal to provide a technology compatibility kit (TCK) to the ASF for its Apache Harmony open-source implementation of Java.
OpenOffice resignations and fork
After Oracle ended OpenSolaris, some members of the similarly open source OpenOffice.org Project became worried about their project's future with Oracle. Thus they formed The Document Foundation and created the LibreOffice fork. The LibreOffice brand was hoped to be provisional, as Oracle had been invited to join The Document Foundation and donate the OpenOffice.org brand.
In response Oracle demanded that all members of the OpenOffice.org Community Council involved with The Document Foundation step down from the Council, citing a conflict of interest. Many community members decided to leave for LibreOffice, which already had the support of Red Hat, Novell, Google, and Canonical. LibreOffice produced its first release in January 2011.
Oracle Grid Engine (previously Sun Grid Engine) was changed to a close-source commercial-only product.
Oracle has changed the software support model to also require hardware support. The new policy states "when acquiring technical support, all hardware systems must be supported (e.g., Oracle Premier Support for Systems or Oracle Premier Support for Operating Systems) or unsupported."
