		<description><![CDATA[This post discusses issue faced by me while working on Materialized view (mview) creation at new site(database).

		<description><![CDATA[There are situations when we see &#8220;temporary segments&#8221; in permanent tablespaces hanging around and not getting cleaned up. These temporary segments in permanent tablespace can be created by DDL operations like CTAS and &#8220;alter index..rebuild&#8221; because the new object is created as a temporary segment in the target tablespace and when the DDL action finishes [...]]]></description>
