[TYPO3-mvc] cli_dispatch.phpsh runs on BE scheduler not in crontab

[Rayuth You (Yuth)]

Hi list

Using extbase 1.2.0, I run task scheduler in BE and it work fine.
But I got nothing when I run from crontab
30 18 * * * php /var/www/demo/typo3/cli_dispatch.phpsh scheduler

My configuration
=====================================================================
$settings = 
unserialize($GLOBALS['TYPO3_CONF_VARS']['EXT']['extConf']['myext']);
$configuration = array(
	'pluginName' => 'Pi1',
	'extensionName' => 'myext',
	'settings' => '< plugin.tx_myext.settings',
	'persistence' => '< plugin.tx_myext.persistence',
	'view' => '< plugin.tx_myext.view',
	'persistence' => array(
		'storagePid' => $settings['storagePid']
	),
	'_LOCAL_LANG' => '< plugin.tx_myext._LOCAL_LANG',
	'controller' => 'ControllerName',
	'action' => 'actionName',
	'switchableControllerActions' => array (
		'1' => array('controller' => 'ControllerName', 'actions' => 'actionName')
	)
);
t3lib_div::_GETset(1,'id'); // Root page uid where we include plugin
t3lib_div::_GETset('ControllerName','tx_myext_pi1|controller');
t3lib_div::_GETset('actionName','tx_myext_pi1|action');
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['extbase']['extensions']['myext']['modules']['Pi1']['controllers'] 
= array(
	'ControllerName' => array('actions' => array('actionName'))
);
$dispatcher = new Tx_Extbase_Dispatcher();
$dispatcher->dispatch('', $configuration);
return true;
=====================================================================

Any solution or hint?
