Exadata and Bash Shellshock

There has recently been a lot of news about the exploit revealed in the bash shell.  While the fix is very quick to implement, there are a couple of tricks that are required to install this update on an Exadata environment.  According to Oracle support note #1405320.1, Exadata storage server versions 11.2.3.x.x and 12.1.1.x.x are susceptible… Read More »

A Big Day at Enkitec

The #enkitecworlddomination bus has a few new stops on the tour… Today was a pretty big day at Enkitec – one that probably comes as a shock to many people.  In case you haven’t heard, Enkitec has been acquired by Accenture, which still sounds a little weird, to be honest.  I’ve pretty much spent my entire career… Read More »

Database Shutdown With crsctl

I noticed something for the first time tonight when I was playing around in the Enkitec lab – something that I have been doing wrong for a while.  When working in the lab, I often rely on the crsctl command to shut down the entire cluster stack for me.  It’s really easy to use “crsctl… Read More »

SCAN VIP Troubleshooting

We had a client that was running into a strange issue on their Exadata where new connections coming in through the SCAN were failing.  After doing some troubleshooting, it was discovered that it was related to one of the SCAN listeners not properly accepting requests from new sessions.  The VIP and listener were running, and… Read More »

Stuck Timezone Upgrades and Smart Scans

I heard a strange report from a client late last week – they weren’t getting any smart scans on their Exadata – a data warehouse, no less (and we checked to see if cell_offload_processing was set to true).  Queries would run normally, but for some reason, the “cell physical IO interconnect bytes returned by smart… Read More »

Virtualization on Exadata?

A while back, I noticed this session in the Open World 2013 content catalog.  I didn’t think much of it at the time, other than that it had a catchy title.  The other day, I downloaded the latest Exadata deployment utility via the OneCommand tool.  I noticed something a little strange when I was going… Read More »

dbnodeupdate.sh on Exadata Compute Nodes

Rene Kundersma at Oracle just published a nifty new utility named dbnodeupdate.sh that will assist with the sometimes-cumbersome process of updating the compute nodes in an Exadata environment.  Starting last year with 11.2.3.1.0, Oracle introduced yum updates for the Exadata compute nodes.  Previously, each Exadata storage server patch came with a “minimal” or “convenience” pack… Read More »
