=== Eviction and Expiration
|
|
|
|
There is a realm cache that holds information about secured applications, general security data, and configuration options.
|
|
This cache is unbounded and does not have a limit on entries. This might scare you a little bit, but the number of entries
|
|
in this cache is pretty low compared to the user cache. There is a user cache that contains user metadata. It defaults to a maximum of 10000 entries and uses a least recently used eviction strategy.
|
|
There are also separate caches for user sessions, offline tokens, and login failures. These caches are unbounded as well.
|
|
|
|
The eviction policy and max entries for these caches can be configured in the _standalone.xml_, _standalone-ha.xml_, or
|
|
_domain.xml_ depending on your <<fake/../../operating-mode.adoc#_operating-mode, operating mode>>.

|
|
+distributed-cache+ eviction policy you want to change.
