TREX Caches

Use

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. To display the TREX caches, use the SAP NetWeaver Administrator.

Features

The TREX caches comprise the following cache types:

Administration cache
Memory cache

Caution
Note that only those parameters and values for the TREX service are described that you have to configure in specific circumstances.

Administration Cache

The administration cache is a memory cache in which objects are stored. The administration cache is used to store TREX commands that are initiated by the TREX administration control.

Key	Value	Description
`cache.trexadmin.capacity`	`100`	Capacity of the cache; this value depends on the number of different search requests.
`cache.trexadmin.defaulttimetolive`	`300`	Expiry time for the cache; specifies in seconds how long the cache entry is to exist.

Memory Cache

The administration cache is a memory cache in which objects are stored. The memory cache is used to store search queries and the associated responses.
