TREX Caches
The TREX caches are used by the TREX infrastructure of the portal to store search results temporarily, for example. You use the configuration of the caches to display the caches and modify them to your requirements. Normally, you do not change these settings. You use the Visual Administrator to display the TREX cache in the J2EE Engine.
The TREX caches comprise the following cache types:
- Administration cache
- Memory cacheNote
For more information about the caches used in KM, see Components and Their Caches .
CautionNote that only those parameters and values for the TREX service are described that you have to configure in specific circumstances.
The administration cache is a memory cache that objects are stored in. The administration cache is used to store TREX commands that are initiated by the TREX administration control.
