Configuring a CacheManager
CacheManager configuration elements and attributes are fully described in the ehcache.xml reference file available in the kit.
Via ehcache.xml
The attributes of <ehcache> are:
name – an optional name for the CacheManager. The name is optional and primarily used for documentation or to distinguish Terracotta clustered cache state. With Terracotta clustered caches, a combination of CacheManager name and cache name uniquely identify a particular cache store in the Terracotta clustered memory. The name will show up in the TMC.
Note: If you employ multiple Ehcache configuration files, use the name attribute in the <ehcache> element to identify specific CacheManagers in the cluster. The TMC provides a menu listing these names, allowing you to choose the CacheManager you want to view
updateCheck – an optional boolean flag specifying whether this CacheManager should check for new versions of Ehcache over the Internet. If not specified, updateCheck="true".
monitoring – an optional setting that determines whether the CacheManager should automatically register the SampledCacheMBean with the system MBean server. Currently, this monitoring is only useful when using Terracotta clustering. The "autodetect" value detects the presence of Terracotta clustering and registers the MBean. Other allowed values are "on" and "off". The default is "autodetect".
<Ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

updateCheck="true" monitoring="autodetect">
Programmatic Configuration
CacheManagers can be configured programmatically with a fluent API. The example below creates a CacheManager with a Terracotta configuration specified in an URL, and creates a defaultCache and a cache named "example".
Configuration configuration = new Configuration()
.terracotta(new TerracottaClientConfiguration().url("localhost:9510"))
.defaultCache(new CacheConfiguration("defaultCache", 100))
.cache(new CacheConfiguration("example", 100)
.timeToIdleSeconds(5)
.timeToLiveSeconds(120)
.terracotta(new TerracottaConfiguration()));
CacheManager manager = new CacheManager(configuration);
