SYMPTOM:
In Strategy intelligence Server 8.x and later, users right-click on the Cache Monitor and perform the 'Cleanup Invalid Caches' action; however, invalid caches still remain in the Cache Monitor.
CAUSE:
This issue happens because these report caches have a History entry. Invalid caches are not cleared if they are associated with a history list message.
ACTION:
Users first have to clear the associated history list entry, then perform the 'Cleanup Invalid Caches' action, to clear such invalid cache entries from the Cache Monitor.
For all report caches that do not have a History entry, performing the Cleanup Invalid Caches' action, does clear the invalid caches from the Cache Monitor.
Note: There is an option called 'Show Caches for History list messages' that appears when users right-click on Cache Monitor. Toggling this setting between on and off (checked and unchecked) determines whether invalid report caches that have a History entry, appear or do not appear in the Cache Monitor, respectively.
For difference between various types of report caches, refer to the following Strategy Knowledge Base Document:
