Procedure 7.1. The distributed-cache Element
The
distributed-cache element configures settings for the distributed cache using the following parameters:
- The
nameparameter provides a unique identifier for the cache. - The
modeparameter sets the clustered cache mode. Valid values areSYNC(synchronous) andASYNC(asynchronous). - The (optional)
segmentsparameter specifies the number of hash space segments per cluster. The recommended value for this parameter is ten multiplied by the cluster size and the default value is20. - The
startparameter specifies whether the cache starts when the server starts up or when it is requested or deployed. - The
ownersparameter indicates the number of nodes that will contain the hash segment. - If
statisticsare enabled at the container level, per-cache statistics can be selectively disabled for caches that do not require monitoring by setting thestatisticsattribute tofalse.
