This year’s last log buffer edition looks at the marvelous and splendid blog posts of Oracle, SQL Server and the MySQL databases which promise to bring more and more next year. This Log Buffer #301 promises to be the anchor for yet another action packed blogging carnival next year.
Shortly before we all went on break for the holiday, Oracle announced the new BDA X3-2. Now I have time to properly sit down with a glass of fine scotch and dig into the details of what is included in the release. Turns out that there are quite a few changes packed in. We are getting new hardware, new Hadoop, new Connectors and new NoSQL. Tons of awesome features are included. Let’s get into it.
In this post, I’ll demonstrate how to deploy the pre-built Oracle VM templates to create a two-node 11gR2 RAC cluster in Oracle VirtualBox.
If you are reading this, it means that world moves on and somebody somewhere was wrong in predicting the end of it. The ageless Log Buffer Edition presents you yet again some cool blog posts just before the holiday season to top up your excitement. This Log Buffer #300 is as sweet as the holidays and as sumptuous as Aussie BBQ. Enjoy
I was recently looking at an issue where a large database server was running out of temp space. The issue had happened in the past, so the goal was to identify what had been causing the system to run out of temp. Although ORA-1555 messages will appear in the database alert log (with query text) when a query runs out of temporary space, they only talk about the query that was “unlucky” enough to be attempting to get space when the tablespace was full, not who was using the temp space.

Screenings, shows, premieres and parties. Where the stars have been spotted this week? No not on the red carpet in LA, but in this Log Buffer Edition. In Log Buffer #299, stars of Oracle, SQL Server and MySQL are twinkling. Get mesmerized!!!
A client recently supplied a list of 50+ SQL IDs that should receive SQL profiles, and I’ve been working with Gwen Shapira to review the list. Further discussion showed that this list had come from the Automatic SQL Tuning feature, installed by default in Oracle 11g. The report includes a list of recommended SQL profiles ordered by “Maximum Benefit”, and in our case it included several hundred statements. The expected workflow, as far as I can gather, is to see the recommendations, look at the before- and after- execution plans, and accept the recommendations. Before blindly accepting recommendations, though, I like to see what exact changes are being proposed. They aren’t listed anywhere in the report, and require some extra work to uncover. The first step is to get the automatic SQL tuning advisor report. (
This is just a small bug fix release of the plugin. It was actually quietly released for a while now of if you have downloaded the plugin recently, you have the latest version. To be sure — check the version in the Console or you will see it in the file name.
Not many of you know that my day to day work focus is Oracle e-Business Suite :). Here goes EBS related blog post …Recently several of my team’s clients upgraded to R12.1.3 version and faced the same problem related to OACORE memory settings.
