The EnhancedAggregationStrategy user preference controls how Discoverer Plus and Discoverer Viewer make use of the Oracle9i version 9.2.0.7 or later database’s enhanced aggregation functionality. The settings control the SQL that is generated for the query, and specify whether there should be an exact match between client request and the aggregation levels retrieved from the database, or whether more aggregation levels are retrieved from the database than are requested by the client.

9.6.2 About setting the timeout value for Discoverer

You specify a Discoverer timeout if you want Discoverer sessions to shut down automatically after a specified time period if no user interaction has occurred during that time. Before Discoverer shuts down, a warning message is displayed in Discoverer Plus. For example, if a Discoverer session is not used for ten minutes, the Discoverer session shuts down. The Discoverer end user must reconnect to use Discoverer again. Discoverer timeout values are specified as follows: ■ In Discoverer Plus, the Timeout value in the pref.txt file specifies the timeout value for more information, see the Timeout preference in Section 9.6, List of Discoverer user preferences . ■ In Discoverer Viewer, the session-timeout value in the web.xml files specifies the timeout value for more information, see Section 9.6.3, How to set the timeout value for Discoverer Viewer
