Crystal Reports Cache
Server
Description
Intercepts report requests sent from clients to the page server. If the cache server cannot fulfill the request with a cached report page, it passes the request on to the Crystal Reports Processing server, which runs the report and returns the results. The cache server then caches the report page for potential future use.
Crystal Reports Processing
Server
Responds to page requests by processing reports and generating encapsulated page format (EPF) pages. The key benefit of EPF is that it supports page-on-demand access, so only the requested page is returned, not the entire report. This improves system performance and reduces unnecessary network traffic for large reports.
Dashboards Cache Server Intercepts report requests sent from clients to the Dashboard server. If the cache server cannot fulfill the request with a cached report page, it passes the request on to the Dashboard server, which runs the report and returns the results. The cache server then caches the report page for potential future use.
Dashboards Processing
Server
Event Server
Responds to Dashboards requests by processing reports and generating encapsulated page format (EPF) pages. The key benefit of EPF is that it supports page-on-demand access, so only the requested page is returned, not the entire report. This improves system performance and reduces unnecessary network traffic for large reports.
Monitors the system for events, which can act as a trigger for running a report. When you set up an event trigger, the Event Server monitors the condition and notifies the CMS that an event has occurred. The CMS can then start any jobs that are set to run on the event. The Event Server manages file-based events, which occur in the storage tier.
File Repository Server Responsible for the creation of file system objects, such as exported reports, and imported files in non-native formats. An Input FRS stores report and program objects that have been published to the system by administrators or end users. An Output FRS stores all of the report instances generated by the Job Server.
Web Intelligence Processing Server
Processes SAP BusinessObjects Web Intelligence documents.
Report Application Server Provides ad-hoc reporting capabilities that allow users to create and modify Crystal reports via the SAP Crystal Reports Server Embedded
Software Development Kit (SDK).
