		<description><![CDATA[Today I&#8217;ve been trying to reproduce in an 11g database one of the problems I faced with 10g&#8212;one on those problems Riyaj described in his Multi-Column Correlation and Extended Stats in Oracle 11g post. And the fun part is that I wasn&#8217;t able to reproduce it. Yet just setting optimizer_features_enable='10.2.0.4' made it show up again. [...]]]></description>

		<description><![CDATA[So, how does one gather statistics on indexes? With InnoDB it&#8217;s one thing, with MyISAM it&#8217;s another thing. This post however, will focus on MyISAM. There are various ways, each having their own drawbacks and positive sides. What about ANALYZE TABLE? It&#8217;s great &#8212; very fast in InnoDB. But with MyISAM a lock occurs while [...]]]></description>

		<description><![CDATA[I got to troubleshoot an amazing situation a few weeks ago.
