03/08/11--14:08: Discussion about Configuration Management (chan 1892010)

03/10/11--05:29: Solaris 11 Express and audio noise (chan 1892010)

If you hear white noise in your speakers and headphones while running Solaris 11 Express, do not waste 2 weeks, like I did, looking for software bugs in the audio driver. Just make sure your audio cables are not too close to the power cables (or apply some insulation).

04/09/11--12:02: A few shortcomings in Oracle ZFS appliances (chan 1892010)

This post was prompted by a few incidents we had with our Oracle ZFS appliance clusters at work this week that have forced us to spend a great deal of time in meetings with IT execs to explain the usual: what happened, why it happened, how to avoid it and are we really safe? My [...]


04/13/11--13:27: Identifying peak usage in Oracle ZFS appliances (chan 1892010)

While investigating performance problems in our Oracle ZFS appliances (read it here), one complain was that sometimes NFS/iSCSI operations were taking 5-20 seconds to return. While checking CPU and memory utilization, nothing was very obvious. We suspected that there was some excessive usage but the NFS graphs didn’t show anything crazy either… until we drilled [...]


04/28/11--08:31: Disable Non-Standard Analytics Datasets in Oracle ZFS Appliances (chan 1892010)

It’s a known fact that increased usage of the Analytics feature can impact performance in Oracle ZFS appliances. Apparently there is a bug in Fishworks that won’t delete the datasets associated with a Saved Worksheet when you remove that Worksheet. Those datasets will still keep humming along in the background, collecting data and probably using [...]


07/01/11--11:02: Veritas Cluster Server Java Console on Fedora 14 x86_64 (chan 1892010)

Since Symantec packaged a 32-bit Java binary with the Java Console package, we need to install a few extra packages for the i686 architecture in order to run it. Download the software here. yum install glibc.i686 libXext.i686 libXtst.i686 rpm -ivh VCS_Cluster_Manager_Java_Console_5.1_for_Linux.rpm /opt/VRTSvcs/bin/hagui Alternatively, if you have Java SE x86_64 installed (download here), you can do [...]


08/04/11--13:59: What do you do when “patents attack”? (chan 1892010)

This American Life has a podcast called “When Patents Attack” that has drawn lots of deserved attention. Even Google, the target of many patent lawsuits, posted on their blog using a similar title. Intellectual Ventures posted a rebuttal and one paragraph got me thinking: The recent story on “This American Life” dramatically portrays the point [...]
