OpenDJ implements an entry cache. The entry cache is not designed to cache every entry in your database, but is instead useful in cases where you have a few, typically large entries that are regularly used. For example, if you have a few large static groups and applications that regularly check group membership, you could cache your group entries.
$ dsconfig create-entry-cache --port 4444 --hostname opendj.example.com --bindDN "cn=Directory Manager" --bindPassword password --cache-name "Large Group Entry Cache" --type fifo --set cache-level:1 --set include-filter:"(ou=Large Static Groups)" --set max-entries:10 --set enabled:true --trustAll --no-prompt
You can use the global setting, entry-cache-preload,
to force OpenDJ to load the entry cache as part of server startup.
$ dsconfig set-global-configuration-prop --port 4444 --hostname opendj.example.com --bindDN "cn=Directory Manager" --bindPassword password --set entry-cache-preload:true --no-prompt
By default, OpenDJ does not pre-load the entry cache.
