It is with great joy that I inform you that we have finally shut off the aging and somewhat cantankerous ovid21, which lived its life as the host of a great many MySQL servers. Our replacement systems are more powerful, robust, and allow us to scale more easily as loads increase on these systems. Congratulations everyone!
We’re lowering our Apache timeout values to 60 seconds on the depts/faculty/staff/courses servers, effective immediately: http://httpd.apache.org/docs/2.2/mod/core.html#timeout This may be decreased further as required. This change will improve availability and responsiveness during high-traffic situations by more quickly clearing out Apache threads which are not serving data or awaiting a TCP response from a client. This should… Read More
As some of the last vestiges of 32-bit uniform access computing are swept away in the face of the brave not-so-new future of 64-bit computing, this is a friendly reminder that you may need to recompile any binaries that are still linking to out-of-date or disappearing 32-bit libraries.
It should come as no surprise to anyone at this point in the game, but we are indeed going to shut off ovid21.u.washington.edu at the end of the month. October 31st, 2012 to be exact. This is the real deal. The out-of-warranty aging ovid21 is just about to take a very well-deserved rest from reliably… Read More

As I’ve written before, shepherding cron on our shared UW hosting systems is one of the most interesting aspects of my job. I had a question today from someone who noted that they had @reboot for some mysql.starter scripts, and */5 or */15 for others. Here’s my response: The */5 (every five minutes) and */15 (every 15 minutes)… Read More
As part of UW-IT’s quarterly “leap forward” day, I spent part of my time exploring alternatives to MySQL. Here’s my brief write-up on what I learned, which is adopted from our internal pages. MySQL is used very often on UW-IT systems and around campus, with over 1,000 individual MySQL servers being run on the Shared Hosting… Read More
Arriving back at my desk at 1:30 after a delicious lunch and almond bubble tea, I noticed quite a few tickets in my queue that all had a subject line akin to “OMG SERVER SLOW!!!! ?!??!!?!! DEPTS SLOW!” Checking my email, I noted a few alerts from our service center about slow website response times,… Read More
Some cronjobs failed to fire beginning Sunday, July 1st, 2012 on ovid01.u.washington.edu. This issue was detected and resolved on Monday, July 2nd, 2012 at approximately 11:00am. Cron should be running normally as of Tuesday, July 3rd, 2012. This was unrelated to the leap second event which occurred over the weekend.
