Scheduled Actions In Alfresco

 A scheduled action has parts

• A cron expression
• A query template
• An action template

At the times specified by the cron expression, the query template is used to generate a query, and the query is run to select a set of nodes i.e.,Spaces and Documents.

just we need to configure the scheduled action in an XML file which is located at config\alfresco\extension\

code here for scheduled-action-services-context.xml

here i am trying to run one script file for every  30 minutes.(make sure first upload that script file to Scripts)
