Software compatibility of Oracle Linux

Since Oracle has taken a so-called "fork" of Red Hat's Linux sources, any compatibility that Red Hat has with software from third parties is invalidated! There may be some compatibility - in case Oracle didn't actually change any of the affected sources from Red Hat (yet) - but these must always be individually tested and verified, either by yourself or by Oracle.

So in case of backup agents, drivers, custom modules or tools, you must always test compatibility of the software you choose with your (Oracle) Linux platform. As a rule of thumb, any Linux software that is certified by the manufacturer to be compatible with Red Hat will not be supported on Oracle Linux, unless the third party explicitely states that is does.

Preventing PuTTY timeouts

Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.

Tuning the nscd name cache daemon

I've been playing a bit with the nscd now and want to share some tips related to tuning the nscd.conf file. To see how the DNS cache is doing, use nscd -g. nscd configuration: 0 server debug level 26m 57s server runtime 5 current number of threads 32 maximum number of threads 0 number of times clients had to wait yes paranoia mode enabled 3600 restart internal passwd cache: no cache is enabled [other zero output removed] group cache: no cache is enabled [other zero output removed] hosts cache: yes cache is enabled yes cache is persistent yes cache is shared 211 suggested size 216064 total data pool size 1144 used data pool size 3600 seconds time to live for positive entries 20 seconds time to live for negative entries 66254 cache hi...

Dell Linux - OMSA Hardware Monitoring

Just getting started using Dell's OpenManage Server Administrator (OMSA) on our Oracle Linux platform. There are some confusing instructions going around so it's not immediately clear what to do, hence my blogging here. :) There is a site on Dell - Hardware Monitoring , as well as a wiki with instruction on how to setup their OMSA tooling using yum or up2date. [update]My first update for their instructions: be sure your server has Internet access, as most servers will use a proxy or so. use export http_proxy=http://yourproxy.example.com:port to configure it just for the session, and setup up2date to use an HTTP proxy by editing the settings in /etc/sysconfig/rhn/up2date .
