		<description><![CDATA[How much memory does my Oracle instance use? How much memory do my database connections use? These are questions that can help with capacity planning of your server&#8217;s Physical and Virtual memory. There are several write ups out there on the web that attempt to address these questions. From what I could gather from them, [...]]]></description>

		<description><![CDATA[I was asked, the other day, to automate the creation of a client&#8217;s weekly report, which is a pivot table of some aggregate data generated by a query. As we know, prior to 11g, Oracle did not have a simple table pivot feature. 11g has changed that, and the pivot clause is certainly useful. It [...]]]></description>

		<description><![CDATA[This has been discussed before by my colleague Paul Moen in his article on Oracle standby recovery rate monitoring, but I recently made a discovery that makes it easier to generate both statistics on log apply performance, and more useful stats too. First, let me say that this discovery is based on my observations and [...]]]></description>

		<description><![CDATA[Have you ever wanted to know where exactly in a datafile segments are placed? Have you ever wondered just how fragmented a tablespace is? How about how much space you could reclaim if the last segment of a datafile was moved out of the tablespace? These questions, and many more, can be easily answered with [...]]]></description>

		<description><![CDATA[Woohoo, I finally got a bit of spare time to blog &#8212; my first blog post ever! I chose to talk about a technique I used at a client&#8217;s site to report the topmost space-wasting objects in an Oracle database. I was looking for a way to detect these objects without having to run some [...]]]></description>
