Much to my surprise, I've had my proposed talk accepted for ApacheCon 2006/US.
This time I'll be speaking about running httpd on OpenSolaris. I'm still a bit unsure about the final content, but I hope to cover:

  • SMF for httpd
  • Least Privileges
  • "zoning httpd"
  • dtracing httpd
  • kssl

The list is bound to evolve as I find the time to actually work on these things.

Opensolaris turns one

First time I heard about the OpenSolaris plans was at ApacheCon in 2004, and at that time it sounded like nothing more than a cunning marketing strategy.
Then we got Solaris 10 and I was really surprised when I saw OpenSolaris becomming reality only a couple of months lateri (one day too late to share my birthday). Congratulations to Sun for pulling off what many of us thought impossible half a year earlier.
For me personally, OpenSolaris has also brought many insights into the internals of Solaris, that I never would have gotten without OpenSolaris and especially the community around it. The Sun engineers blogging, turning up at conferences like LISA and ApacheCon, helping out on #opensolaris and sharing the development process on opensolaris mailinglist - it has been absolutely amazing.

Sun has also been very generous to the ASF where I've had the joy of running our Sun v40z and really should be working on bringing our new and shiny T2000 up to speed, but we're still looking for some storage to add because the 4 internal drives are pretty much useless for anything we could think of doing with it. (I'll try to blog a bit more about that box during ApacheCon EU where I'm hoping to get a small break from work ;).

On a personal note: I quit working for ... on may 1st because I got a offer to join some really great people in a startup and I was happy to accept because working full time on Solaris isn't exactly the best career move when you're working for one of Suns largest competitors.

Patching and Fair Share Scheduling

I spent a very long time today getting the ASF zones server patched for the recent sendmail vulnerability. The Sun Alert and the Interim Relief patch were simple enough except for the dependency on 118844-30 which again depends on a grub bootloader update. One thing lead to another (or should I say: one patch led to another) and with me playing it safe (the machine is 9 timezones away) and the mess of having to sort out patches by hand it all ended up taking 4 or 5 hours. I'm used to having support contracts in order and TLP/EIS at hand at work, so this ended up taking a lot more time than I expected.

With the day being more or less gone anyway, I decided that I might as well go ahead and implement Fair Share Scheduling.
So far every zone got its own pool and each zone (except global) got the same number of shares. I doubt anyone will notice this change in their day to day running of things on the server, but in the case where something goes haywire and starts soaking resources, I hope the rest of the zones won't notice. I plan to let it run for a while and then see if there is a need for adjustment.

Sunny Day

Tuesday last week I went to a Sun thing titled "Powering the Participation Age". Most of the day was spent chatting to Sun reps and listening to a couple of semi technical presentations. One of the presentations covered the T2000 servers and was quoting Colm MacCárthaigh's and his T2000 testing. Of course I couldn't keep quiet and had to mention that the numbers were probably far from what Colm would get in later testing and his latest posts adds about 1/3 by upgrading to Solaris Express, but the really amazing thing is that he gets better performance running Linux on the T2000!

Scott McNealy also made an appearance and did a very good job at explaining what Sun has been doing recently and why. For the first time, I began to understand where they're going and I'm not as worried as I used to be. Only time will tell wether they will succeed. As usual, Scott managed to make fun of the company that I won't be working for much longer, maybe I'm biased by having made the decision, but he wasn't far off the mark - if anything, things are probably worse than he joked about :)

Mysql on the T2000

T2000 Ian Holsman has a nice writeup of the benchmarks he has been doing with the T2000 in "How does MySQL perform on a sunfire?".
I've still got plenty of ideas for sqeezing a bit more out of the box, but I don't really have much time to test it myself before I don't have access to the T2000 Try & buy at work.
