Oracle has released the much-anticipated version of cellsrv compatible with Oracle Database 188.8.131.52 (patch #16980054). Before thinking about upgrading, read MOS note #1571789.1 carefully. Unless you are planning to run database 12c on your Exadata, it would be advisable to continue down the 11.2 branch (more...)
Today, Oracle announced the Exadata X4-2 model. The X4 has some considerable improvements, namely:
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 (more...)
Just a quick reminder - I'll be presenting my "Getting Ready for Exadata" seminar in London on July 1. We'll cover various topics on what you need to know before you purchase an Exadata and how to manage one of these systems on a daily basis. We'll have lots of (more...)
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 184.108.40.206.0, Oracle introduced yum updates for the Exadata compute nodes. Previously, each Exadata (more...)
This is something that is almost completely off-topic, but something I've found myself doing quite a bit at Enkitec. You see, we keep adding new hardware (Big Data Appliance in August, new Exadata X3-2 earlier this year), and that means that we need to add a bunch of DNS entries (more...)
When the 220.127.116.11.1 release of the Exadata Storage Server software was released, I was a little excited. There were numerous oneoff patches for the previous release, 18.104.22.168.0, which was the first version to support the Exadata X3, writeback flashcache, run UEK on the X#-2 systems, etc. With that many large changes introduced in one version, it was likely to see some bugs in the .0 release. Fortunately, Oracle was quick to fix many of those issues, but it resulted in several separate patches to update the cellsrv software.
I was working with (more...)
Well, it's been a really busy past few months, and I hate to admit it, but I've been neglecting this space more than anything. Despite having many different posts in the works, nothing is quite finished yet. I do have a little time to mention a few of my upcoming speaking events, though.
First, I'll be in Denver for the Rocky Mountain Oracle Users Group Training Days 2013, February 11-13. Enkitec has more than a few sessions during the conference, ranging from Exadata to Big Data to APEX. Check out the agenda for a full list. Also, we'll have an (more...)
Well, it's finally public, so we're able to openly talk about the new Exadata X3 systems. Looking back on my pre-openworld predictions, I was pretty close on a few things. I was correct on the database servers, which will have Xeon E5-2690 CPUs (8 core, 2.9GHz) with 128GB RAM upgradeable to 256GB. It looks like we won't get active/active Infiniband for a while, since the cards in there are staying the same. On the X3-8, the compute nodes are staying the same, for reasons detailed by Kevin Closson a few weeks ago. I also previously blogged about the (more...)
