San Francisco is bracing for the annual invasion. The airport's jammed, the tweets are flying, and the numbers are crazy: more than 50,000 attendees and 2,500+ sessions, taking over Moscone Convention Center, two streets, Union Square, and seemingly every hotel in town (98,000 hotel room nights).

So yeah, it's busy.

And it's not just OpenWorld--we've also got JavaOne, MySQL Connect, and four other sub-events going on as well.

Speaking of JavaOne, you can find Solaris-related activity there, too -- I've highlighted one hands-on lab below.

Here's a last pre-event roundup of activities for consideration; enjoy the show(s)!

Monday, October 1st:

3:15 PM - General Session: Accelerate Your Business with the Oracle Hardware Advantage
(GEN9691, Moscone North Hall D)

John Fowler, head of Oracle's Systems organization, will talk about Oracle hardware technology and how it's co-engineered with other key technologies, including Oracle Solaris.

Tuesday, October 2nd:

10:15 AM - Building an IaaS Platform with SPARC, Oracle Solaris 11, and Oracle VM Server for SPARC
(CON4431, Moscone South 270)

Get the birds-eye lowdown (whatever that means) on how U.S. Cellular  built its Infrastructure as a Service (IaaS) cloud delivery platform with Oracle’s SPARC T4 servers, Oracle Solaris 11, Oracle Solaris Cluster 4, and Oracle VM Server for SPARC. The session covers the high-level design, business case made, implementation details, and lessons learned.

11:45 AM - Oracle Solaris 11 Panel: Insights and Directions from Oracle Solaris Core Engineering
(CON8790, Moscone South 252)

This has been one of the livelier Solaris-related sessions in years past (and I'm not saying that just because I get to moderate it this year). A panel of core engineers responsible for a wide range of key Solaris technologies will talk about some of the interesting work they've been doing -- but mostly we keep time open for the panel to take questions from attendees, because that's the fun part.

Wednesday, October 3rd:

10:00 AM - Tracing Your Java Application Tuning on Oracle Solaris with DTrace
(HOL10214, Hilton San Francisco, Franciscan A/B/C/D)

This JavaOne hands-on lab will show how to use the DTrace framework to dynamically trace your Java applications on Oracle Solaris and uncover new tuning opportunities.

Thursday, October 4th:

12:45 PM - Oracle Solaris 11: Optimized for Oracle Database, Oracle WebLogic Server, and Java
(CON8800, Moscone South 252)

Explore how Oracle Solaris 11 has been built to be the best platform for the cloud and enterprise applications, with built-in optimizations to improve performance and deliver unique functionality with Oracle Database, Oracle WebLogic Server, and Java.
