Eerst maar wat nieuws van het front
Tevens zijn er nog wat omheinings palen geplaatst te weten voor; Teachalot, Jeltje, [DPC]LightLuke, ROADHOGG, Sake van Pelt, Thijs en ramon.bertrand
TEB staat ook vandaag weer rotsvast op 1. Mijn DB stijgt een paar plaatsjes
.
Een hoop plusjes ook, en een in het bijzonder, en dat is RWaC wat de FOTD award oplevert.
En ook overal gebeurd er iets en dat is dat DB een plaatsje stijgt

wat gevolgd wordt door ander goed nieuws. E wel dat er twee nieuwe koeien in de DPC weide zijn gearriveerd, genaamd Xwigone en krakbracket. Welkom beide22 Sep 2009 20:43:14 UTC
Today was an outage day, with nothing special to report on that front. One interesting note is that our master mysql database server (mork) has 24 processors and 64 GB of memory, and the replica server (jocelyn, which used to be the master) has 4 processors and 28 GB of memory. Eric recently cleaned out really old rows from the beta result table - now the entire database fits better in memory on jocelyn, and in turn this database engine generally performs better than mork. How could this be? Because despite have far less memory and processors, jocelyn has more disk spindles (and faster disks, for that matter) than mork. Not really all that surprising, but it's fun to see our suspicions about disk performance confirmed with memory being less of a bottleneck. In any case, both servers are zippy and today's outage wasn't very long, was it?
So the weekend went by with nary a blip, or even a single alert from my web of alert scripts. This pretty much never happens. We always get kind of warning, severe or otherwise - high load on this server, replica database is falling behind, rising temperatures in the closet... but nope. Everything was just fine.
However yesterday we did have one short traffic dip due to the science database getting locked up on too many internal user queries, so the splitters weren't creating work for a couple hours there. No biggie - we killed the queries and informix sprung back to life. It is a bit worrisome how locked up the database can get, though, and it's hardly predictable when (or why) it does.
I'm actually running my software radar blanker through an entire 50GB test file right now. It processes in roughly twice real time (meaning a file containing n hours of data takes 2n hours to find radar and blank it). Not to worry - we can run many of these in parallel. I could also make several code optimizations if need be. Anyway, I'm hoping by the end of the week to trust this suite of software enough to start processing our large backlog of 2007-2008 data by next month.
Oh yeah one more thing - we do know that "queries/second" field is blank on the server status page. For some reason the same exact informational query on one server returns in a different format
than the other, so our general "db stats" script is sorta broken. Bob is fixing it.
