By default, information about an active ControlPoint operation is kept in a server memory cache for 20 minutes. Within this time period, a user can:
·initiate and run a ControlPoint action or analysis
·return to results of an analysis from which he/she has drilled down
·download search or analysis results.
After this time period has expired, the cache is cleared and the operation must be re-initiated.
ControlPoint Application Administrators can change the number of minutes that analysis data is held in server memory cache by modifying the Value of the ControlPoint Setting Time to Retain Page Data in Cache.
NOTE: This is an Advanced Setting.
If you increase this value, a ControlPoint operation will remain "active" for a longer period of time. Keep in mind, however, that the higher the value is set the longer information about the operation will consume memory, which may be a burden on server resources (specifically, the size of the application pool process supporting the Web application that hosts the ControlPoint Configuration Site collection).
If you decrease this value and the server cache is cleared before a ControlPoint operation (such as a Copy/Move) has completed, the Task Audit that is generated at the conclusion of the operation will contain no data. (However, a completed Task Audit for the operation can still be invoked from the Manage ControlPoint panel).
