If you need additional information about Scheduled Jobs in SharePoint (to have an overview look @ „Central Administration > Operations > Timer Job Definitions „) go to the table „Objects“ in the Config Database and filter for the field „Name“.
Then you can copy the XML-String from Field „Properties“. In this string you’ll find additional information.
Or of course you can programm an own application which looks for all available Jobs
foreach (SPJobDefinition job in siteCollection.WebApplication.JobDefinitions)
