The Level 2 (L2) cache provides out-of-transaction caching of Java objects inside the
SkyVault system. SkyVault provides support
for EHCache. Using EHCache does not restrict the SkyVault system to any
particular application server, so it is completely portable.
The L2 cache objects are stored in memory attached to the application scope of the server. Sticky sessions must be used to keep a user that has already established a session on one server for the entire session. By default, the cache replication makes use of RMI to replicate changes to all nodes in the cluster using the Peer Cache Replicator. Each replicated cache member notifies all other cache instances when its content has changed.
If you have issues with the replication of information in clustered systems, that is, the
cache cluster test fails, you may want to confirm this by setting the following properties to
true in the SkyVault-global.properties file:
system.cache.disableMutableSharedCaches= system.cache.disableImmutableSharedCaches=
