		<description><![CDATA[Today I want to show what kind of IO performance we can get from Oracle Database Appliance (ODA). In this part, I will focus on hard disks. That&#8217;s right &#8212; those good old brown spinning disks. I often use Oracle ORION tool to stress-test an IO subsystem and find it&#8217;s limits. It&#8217;s a very simple [...]]]></description>

		<description><![CDATA[If you have an extremely busy OLTP system with a physical standby ready for a manual role transition, and you want to run very heavy reporting queries without affecting the system, consider using a separate report database with downstream capture configuration. Yes, it is very easy to configure, and it will have no performance impact [...]]]></description>

		<description><![CDATA[One of the customers (actually a prospect) here in Australia asked me about minimal Oracle licensing on a quarter rack database machine. This prompted a thought of using Oracle Standard Edition instead of full blown Enterprise Edition with bunch of options. Before even going into possibility of using Oracle SE for the database machine, let&#8217;s [...]]]></description>

Now that I, apparently successfully, predicted OLTP Database Machine on Sun hardware, I had to wake up before 6AM in Sydney to tune into Larry&#8217;s joined with Sun Microsystems webcast (just to learn [...]]]></description>

		<description><![CDATA[As some of you probably already noticed, there was a thread on AskTom discussing the scalability tests I did back in 2007. You are welcome to read the entire thread, but in a nutshell, Tom Kyte claimed that my tests did not reflect how one would use the result cache in the real world. What [...]]]></description>

		<description><![CDATA[This article will discuss how to make many-to-many relationships in data warehousing easily queried by novice SQL users using point-and-click query tools. This is a big problem with Oracle Discoverer-like tools where the metadata layer is basically a set of pre-joined tables from which the user simply clicks on columns and hits the run button.
