The Database Modules window is available only for Oracle database servers. The Module field is often identical to the Program field unless it has been programmatically set with a call to DBMS_APPLICATION_INFO. Some packaged applications, such as Oracle E-Business Suite, automatically set the Module field with relevant identifiers.

The Database Modules window shows you the names of the Top N busiest modules on the Oracle database server. To see the Top N Queries run on the database by a module, click a module name and then click View Top Queries. From the Modules top queries page, to see more details about a query you can double-click a query to open the Query Details window.
