This section describes the cleanup service for portal pages and their dependent resources.
Portal resources, such as pages, components or portlet instances are kept persistent in the portal database. When an administrator deletes a page, all its derived pages and dependent resources and content are deleted with it. The actual deletion can take considerable time, depending on the size of the portal and the number of resources affected by the deletion. Therefore, if the deletion takes place immediately after the user completes the deletion task, this might impact portal performance for users. On the other hand, if the deletion is delayed and scheduled for an off peak time, it will not affect portal response time and thereby user experience.
The delayed deletion of pages is performed by a cleanup service.
You can configure the deletion cleanup to happen either immediately when you delete the page or later:
You can change between the immediate and delayed deletion of portal pages by configuring the property value scheduler.cleanup.enabled in Data Store Service as described in Set configuration properties:
Set this property to true if you want the deletion of pages to be delayed and performed by the scheduled cleanup service. This property defaults to true, if the portal installation is based on a version of IBM WebSphere Application Server that includes the Scheduler service.
By its default schedule configuration, the cleanup service runs weekly, on Saturdays at 8 pm.
Notes:
You can also configure the delayed deletion schedule according to your requirements by using the XML configuration interface of IBM WebSphere Portal Express. You can define a daily, weekly, or monthly schedule. You can also use the XML configuration interface to run individual cleanup tasks at arbitrary intervals.
Note: In order for your customized schedule to be observed by the portal, you must enable the property scheduler.cleanup.enabled by setting it to true in the Data Store Service as described in Set configuration properties. For more details about this property refer to Configuring immediate or delayed deletion of portal pages. Parent topic: Configuring portal behavior Related tasks
