Dynamic cache service multi-cell and multi-core group invalidation enables caches created in different cells to be synchronized without the cache entries being replicated across cell boundaries. When this function is enabled for either servlet and object cache instances, data gets cached in both cells as a result of the cells handling the same traffic. When a cache entry is invalidated, using the Java Message Service (JMS), the ID of the invalidated cache entry is sent to a peer cell. The receiving cell uses a service integration bus to process the invalidation. This function can also be used to propagate invalidations to other core groups in the same cell.Disabling template-based invalidations during JSP reloads
By setting the Java™ virtual machine (JVM) com.ibm.ws.cache.CacheConfig.disableTemplateInvalidation custom property to true, the template-based invalidations are disabled during JSP reloads.Dynamic cache provider for the JPA 2.0 second level cache
Learn to use the WebSphere Application Server dynamic cache service as a Java Persistence API (JPA) second level (L2) cache provider. JPA 2.0 has standardized the L2 cache interface. WebSphere Application Server supports the JPA standard. The dynamic cache service plugs in as a level 2 cache provider to JPA. The L2 cache boosts the performance of your JPA application and you can configure and monitor the dynamic cache service for your JPA application in the WebSphere Application Server environment.
