Hi. I'm a Unix Administrator, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: Unix.

We never learn.

Google Play All Access Music? Great idea!

Flash player required? Ugh.

I want off this planet.

Ka-blooey said the cluster.

Spent a bit building out an Oracle RHCS cluster for a customer. So Oracle Engineers install Oracle 11g, I configure the RHCS cluster, and I notify the Account Manager that all that's left are a few tests.

Simple tests. Like, "clusvcadm -R oracle-svc". Ok, passed that. "clusvcadm -r oracle-svc -m db2". Passed that one, too. Now to the fun tests...

Shifting gears

I've hit that point in my career where I cannot hide behind a technical manual all day. I've hit that place where, regardless of where I go from here, I will hit layers 8 and 9 of the OSI model (if you don't know the joke, that's finances and politics, respectively).

Who drives finances and politics? Unlike the other layers, which are driven by physics, electronics, and computer logic, layers 8 and 9 are driven by humans. In my typical quest for understanding (and perhaps for the...

Time Warner IPv6 pains

Posted 04-23-2013 at 01:17 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I asked TWC about ipv6 a while back, and the tech I got on the phone was as clueless as they come. Oddly, I could see router advertisements with link-local address (modem playing games, or so I thought), so I fired up rtsol and cried as it failed repeatedly.

A bit later, I noticed that with the kids competing for bandwidth and my wife gaming, we were starting to saturate the 20 Mbps we were getting. I call TWC and upgrade to the 50 Mbps package.

Then something peculiar...

Paging? Swapping? Which is it?

Posted 04-15-2013 at 11:52 AM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

It's a bit big to be called a "one-liner", but this "script" will give you a short overview of paging levels vs. swapping levels on your machine.

Set T=<seconds> to whatever timeframe you want to test for.

Code:
T=5; ( vmstat -s; sleep $T; vmstat -s ) | awk -v T="$T" -F'[(/)]' '/pages paged in/{ pgpio=pgpin; pgpin=$1 } /pages paged out/{ pgpoo=pgpon; pgpon=$1 } /pages swapped in/{ pgsio=pgsin; pgsin=$1 } /pages swapped out/{ pgsoo=pgson;
