How to execute info * engine tasks..??

You need to provide a VM/adapter name in your task. The best method is to get the value of wt.federation.ie.VMName from wt.property. It is something like reverse of your server name with a .Windchill appended to it. 

<%
String instance = wt.util.WTProperties.getLocalProperties().getProperty("wt.federation.ie.VMName");
%>
<ie:webject name="Query-Objects" type="OBJ">
<ie:param name="instance" data="<%=instance%>"/>
<ie:param name="WHERE" data="name='$(@FORM[]name[])'" default=""/>
<ie:param name="TYPE" data="wt.maturity.PromotionNotice"/>
<ie:param name="ATTRIBUTE" data="*" delim=","/>
<ie:param name="GROUP_OUT" data="PromotionNotice"/>
</ie:webject>
