services

`services`

Used in: cluster-config.

Description

Specifies the configuration for Coherence services.

Service Components

The types of services which can be configured includes:

ReplicatedCache - A cach service which maintains copies of all cache entries on all cluster nodes which run the service.
ReplicatedCache.Optimistic - A version of the ReplicatedCache which uses optimistic locking.
DistributedCache - A cache service which evenly partitions cache entries across the cluster nodes which run the service.
SimpleCache - A version of the ReplicatedCache which lacks concurrent control.
LocalCache - A cache service for caches where all cache entries reside in a single cluster node.
InvocationService - A service used for performing custom operations on remote cluster nodes.

Elements

The following table describes the elements you can define for each service element.

Element	Required/Optional	Description
`<service-type>`	Required	Specifies the canonical name for a service, allowing the service to be referenced from the `service-name` element in cache configuration caching-schemes.
`<service-component>`	Required	Specifies either the fully qualified class name of the service or the relocatable component name relative to the base Service component. Legal values are: `ReplicatedCache` `ReplicatedCache.Optimistic` `DistributedCache` `SimpleCache` `LocalCache` `InvocationService`
`<use-filters>`	Optional	Contains the list of filter names to be used by this service. For example, specifying `use-filter` as follows <use-filters> <filter-name>gzip</filter-name> </use-filters> will activate gzip compression for the network messages used by this service, which can help substantially with WAN and low-bandwidth networks.
`<init-params>`	Optional	Specifies the initialization parameters that are specific to each `service-component`. For more service specific parameter information see: ReplicatedCache Service Parameters DistributedCache Service Parameters InvocationService Parameters
