		<description><![CDATA[Yesterday, I received the following question from a TVD$XTAT user:
XCTEND lines are reported as &#8220;COMMIT/ROLLBACK (synthetic)&#8221;. Using Goolge and Metalink I can&#8217;t find any other resources describing &#8220;COMMIT/ROLLBACK (synthetic)&#8221;. This term seems not be widely used, although Hotsos uses the same term. Could you please elaborate what exactly that is and why it possibly happens?

One of them is the value &#8220;plh&#8221; in the PARSE, EXEC and FETCH lines. This new value provides the execution plan hash value.
