NIEUWS UPDATE
6 Jan 2011 22:15:44 UTC
The informix tweak planned yesterday was postponed and completed today. Why was it postponed? Because the weekly science backup (which happens in the background - doesn't require an outage like the mysql database) wasn't done yet. Normally it takes a few hours. But during major activity it looks like it'll take 10 days! Jeff stopped the ntpckr/rfi processes and that sped things up.
This clearly points out oscar's inability to handle the crazy random i/o's we desire, though to be fair oscar is indeed operating better in its current state than the old science database. There's still MANY knobs to turn in informix-land before we need to add more disk spindles. For example, we still haven't given all the memory available in the system over to informix. The tweak we made today added an additional 20GB to the buffers. Note that it takes a bout a week to fill these buffers, so we won't notice any improvement, if any, until then.
Meanwhile I've been back to working on my various ntpckr and data testing projects. It's hard to page these pieces of code back into my RAM once they've been flushed to disk - know what I mean?
