High Interactivity Application Deployment Planning

Deploy high interactivity applications in a way that maximizes local browser performance. For an overview of high interactivity mode, see About High Interactivity and Standard Interactivity.

NOTE:  Siebel Open UI, a new user interface deployment option, is an alternative to the high interactivity client (for employee applications) or the standard interactivity client (for customer applications). Most of the information in this chapter pertains only to high interactivity or standard interactivity and has not been significantly updated. For more information about Siebel Open UI, see About Siebel Open UI.

Several factors influence this performance:

• Default column display. Users can select which columns to display in list applets. Deploy applications with the minimum number of columns set to display. Then allow users to select which columns to add. Displaying fewer columns improves performance by minimizing the number of Web templates and amount of data required to build views in response to user requests.
• View layout caching. Administrators can determine the number of views to be cached by the user's browser. When a view is cached, subsequent visits cause a user request for only a data update. The Web templates required to build the view are retrieved from the browser cache. The Siebel Server does not rebuild them again. Caching views improves response time. Set the number of views to be cached as high as practical.
• User login. The first login is generally the most time-consuming. The client infrastructure caches the main components of the application on first login. Subsequent logins require far fewer resources. Cached objects remain on the client computer until the cache is cleared or a new version of the application configuration is available.
• Browser version. Use the latest supported version of Microsoft Internet Explorer in your application development, testing, and deployment environments. Besides fixes, the latest versions frequently include performance enhancements and improved ActiveX and Java Runtime Environment (JRE) support.

NOTE:  Siebel Web Clients running in the high interactivity client use ActiveX controls and JavaScript, and require the Java Runtime Environment (JRE). These items can be downloaded to the browser automatically. For more information about client and browser requirements, see Siebel System Administration Guide and My Oracle Support Certifications.
