Configuring the TaskSpace application - EMC Community Network

Configuring the TaskSpace applicationThe EMC Documentum TaskSpace Deployment Guide and EMC Documentum xCelerated CompositionPlatform Best Practices Guide provide information on configuring the TaskSpace application server.The following topics provide information for configuring the TaskSpace application.Disabling drag and dropDepending on form complexity, drag and drop can incur up to 5 seconds of performance overhead.To disable drag and drop, set the tag in the \taskspace\app.xmlfile to a value of false.falseDisabling data-grid resizingResizing of data grids, like drag and drop, can incur a significant amount of performance overhead. Ifyou disable drag and drop and data-grid resizing, you can achieve an 18% improvement in responsetime for task list rendering (Figure: Seconds saved by disabling drag and drop, and data grid resizing).Disable data-grid resizing by adding the parameter in the \taskspace\app.xml file and setting the value to false.………falseFigure: Seconds saved by disabling drag and drop, and data grid resizing

Increasing cache timeTaskSpace client-side caching provides significant single-click performance improvement by reducingthe overall number (Figure: Caching impact for number of requests) and size (Figure: Caching impactfor size of request) of requests associated with common transactions.Set the value of the ClientCacheControl filter in the \WEB-INF\web.xml file toa high number as follows:ClientCacheControlcom.documentum.web.servlet.ResponseHeaderControlFilterCache-Controlmax-age=604800Configure the browser not to clear the cache when the browser closes.Figure: Caching impact for number of requests

Figure: Caching impact for size of requestCaching also reduces response time associated with common transactions (Figure: Caching impactfor response time).Figure: Caching impact for response timeTurning off Java annotationsTaskSpace does not support the Java annotation feature. The Java annotation feature can have asignificant TaskSpace performance impact (approximately 10%) on Tomcat 6.x and later applicationservers. For Tomcat 6.x and later, turn off the annotation feature by setting the metadata-completeparameter in the \WEB-INF\web.xml file to true.Note: You do not need to turn off the annotation feature for Tomcat 5.x and earlier.

Turning on page servingThe ACS page serving configuration provides a substantial performance improvement (Figure:Document viewing with ACS page serving) for document viewing.Figure: Document viewing with ACS page servingSet the following ACS configuration data in the{clientserver}\webapps\taskspace\wdk\config\imaging\ ivf_config.xmlconfiguration file:• Set Content Server ACS ON/OFF.• Set Page Serving Level or Document Serving Level.• Set Page Serving Level Threshold (in bytes).Note: Not all file formats can use ACS.
