We recently integrated MySQL 5.0.45 version with Open Solaris. MySQL 5.0.45 is available in SXDE 01/08. Sun Studio was used to compile MySQL on both Solaris SPARC and Solaris AMD64 platform.

This blog entry describes the changes that were made to improve MySQL performance using Sun Studio:

• Enable function inlining when Sun Studio is used.
  • The header file univ.i has the following code:
    
    • #if !defined(GNUC) && !defined(WIN)
    • #undef UNIV_MUST_NOT_INLINE /\* Remove compiler warning \*/
    • #define UNIV_MUST_NOT_INLINE
    • #endif
  •  Modifying it to add Sun Studio compiler as under:
    • #if !defined(GNUC) …

MySQL 5.0.45 is integrated with Open Solaris build 79. It is available in Solaris Express Developer Edition (SXDE) 01/08. MySQL 5.0.45 is integrated with Solaris Service Management Facility (SMF).

This blog entry describes the steps that were taken to integrate MySQL with SMF.

First a quick recap of what is SMF:

SMF is the core component of the predictive self-healing technology available in Solaris 10, which provides automatic recovery from software and hardware failures as well as adminstrative errors.
Some of the advantages of using SMF are as under:

• Failed services are automatically restarted in dependency order, whether they failed as the result of administrator error, software bug, or were affected by an uncorrectable hardware error.

• More information is available about misconfigured or misbehaving …

As part of planning our integration into Sun, we surveyed all MySQLers on their opinions regarding Sun, their concerns and ideas. Amongst concerns, “retaining the MySQL Culture” ranked second.

But what exactly is “The MySQL Culture”? That’s never been written down, and defining culture is usually a matter for anthropologists, not Open Source companies.

So we decided to ask. Instead of engaging field anthropologists, we just added a question to the survey. And did we get answers! This is what the foremost experts, i.e. our employees, think constitutes MySQL Culture:

• A diversified and distributed workforce
• Lack of empire building
• A place for geeks
• Lack of …

Is 2008 going to be the Year of the Acquisition? Activity in 2007 was on the rise but now things seem to be at full speed.

• I remember when Alta Vista and Excite! were the hot search engines, my how the world has changed.  It looks like it’s narrowing down to a two horse race with Microsoft putting the moves on Yahoo! for about $44.6 billion (Notes from SearchEngineLand). I guess it’s really on now, Google versus Microsoft in a search engine death match.
• Yahoo! acquired Zimbra last year. I wonder …

“What will happen to us now?” That’s the usual question for most employees in any acquired company, and MySQL AB is no exception. And given that less than 10% of MySQL AB is at the integration kickoff here at Sun’s headquarters in Menlo Park, more than 90% are probably also asking “what is that small group of people deciding?”.

Judging from the feedback I’ve got, those questions are of relevance not just for MySQLers, so let me re-state a couple of “old truths” and come with a few observations from MPK. (Do note the lingo — MPK is Sun speak for Menlo Park; I’m trying to learn…).

First thing, it’s “Business as Usual”. We’re just making plans for actions that can follow upon closure. Closure is planned (as announced earlier) in late Q3 or early Q4, where the Sun quarter numbering should be translated to mean late Q1 or early Q2 for the rest of the world.

…

One perhaps not-so-expected attendee at the MySQL-Sun Integration Kickoff is Josh Berkus, of PostgreSQL fame.

Zack Urlocker, Eduardo Pelegri-Llopart and Josh Berkus.

Josh gives valuable feedback within the Community track of the Integration Kickoff. Mind you, Jonathan Schwartz has reiterated Sun’s support for PostgreSQL:

What happens to your commitment to PostgreSQL?

It grows. The day before we announced the acquisition, and within an hour of signing the deal, I put a call into Josh Berkus, who leads our work with Postgres inside of Sun. I wanted to be as clear as I could: this transaction increases our investment in open source, and in open source databases. And increases our commitment to Postgres - and the database industry broadly. The same goes for our work with Apache Derby, and our JavaDB.

Josh says it exactly right on his blog - Sun …

Yesterday here at the MySQL-Sun Integration Kickoff, MySQL Co-Founder Michael “Monty” Widenius and I met with Sun’s CTO Greg Papadopoulos. For the beginning of the meeting, also Sun’s CEO Jonathan Schwartz popped in.

And just as when the founders met Sun’s Rich Lang and David Douglas prior to the agreement being announced, this was a very positive meeting. Lots of mutual respect, and lots of mutual interest in listening to what the other party has to say. Relaxed atmosphere, full of anticipation.

The areas touched upon ranged from the right for developers to spend time on other FOSS projects besides MySQL, over the newly released Maria storage engine to possibilities for deep technical integration between MySQL and Sun’s software and hardware.

I could sense a mutual hunger for action, for change, and for making things happen. …

For a split second, I thought Jonathan said he thought of Sun’s acquisition of MySQL as “hypocritical”. Of course, what he said was “Hippocratical”, in the sense of the old Greek with the oath for doctors: “Do no harm.”

Jonathan appeared in front of the integration team with MySQL and Sun employees here in Menlo Park. What he said was very comfortable to hear for MySQLers old and new:

• Jonathan sees a great strategic fit between MySQL and Sun, and that’s the prime precondition for any good acquisition.
• The strategic fit thinking is seconded by financial analysts and technical observers alike.
• “Honour the community“: Jonathan sees the community of MySQL users as the starting point for all decisions related to the integration.
• “Honour the employees“: Jonathan respects the group of MySQL …
