OBS prevents the PC from entering sleep mode when replay buffer is on. To configure query caching, you must furthermore call setCacheable(), passing true, on each should stop replay buffer / on hibernate / sleep mode enter and relauch it after the PC exit the hibernate / sleep mode, if it was running. The meaning and effect of each possible value is documented below in the section on cache concurrency strategies. The possible values for the usage attribute of the cache element are as follows: Second-level caching, add elements to the class’s mapping file as in the following example, or use the To configure mapped classes and Collection-typed fields to use Hibernate, to use caching on a case-by-case basis. Must also configure Hibernate to use second-level caching, and query caching ifĭesired, by setting the appropriate Hibernate configuration properties toįurthermore, you must configure each entity class mapped by Hibernate, and each Collection-typed field mapped by In addition to setting the _class property, you Property in Hibernate configuration to .cache.CoherenceRegionFactory.įor example, include the following property setting in : Ĭom.CoherenceRegionFactory To configure Coherence as the Hibernate second-level cache, set the _class Of the the Hibernate Core Reference Manual at. Hibernate manages data inĪn internal representation in the second-level and query caches, meaning that theseĬaches are usable only by Hibernate. The query cacheĬaches the result sets generated by Hibernate queries. The second-level cache is responsible forĬaching records across multiple Sessions (for primary key lookups). The second-level and query caches span multiple transactions, and support the As a non-clusteredĬache, the session cache is managed entirely by Hibernate. Is a transaction-level cache of persistent data, potentially spanning multipleĭatabase transactions, and typically scoped on a per-thread basis. The session cache caches entities within a Hibernate Session. Configuring Hibernate Second-Level and Query Caching Note: that the Coherence Hibernate second-level cache implementation depends by default Or you can build the Coherence Hibernate second-level The easiest way to do so is to build and execute your Hibernate application with Maven,Īnd add the following dependency to your application’s pom.xml: Īlternatively, you can download coherence-hibernate-cache-xx-2.0.0.jarįrom a Maven repository (e.g. Obtaining a distribution of coherence-hibernate-cache-xx-2.0.0.jarįor the respective Hibernate version of your application. Installing the Coherence Hibernate second-level cache implementation amounts to Installing the Coherence Hibernate Second-Level Cache Ultimately, you should make a decision that is most applicable NOTE: Before you use the Coherence Hibernate Cache support, please also consider Run in a cluster of application servers accessing the same database. Using Coherence as a Hibernate second-level cache implementation may be a good fitįor Java applications that use Hibernate for data access and management, and that In the Hibernate Core Reference Manual at. On Hibernate second-level caching, see the relevant chapter Use the Coherence Hibernate second-level cache implementation. Should have a good understanding of Hibernate second-level caching to successfully Of Coherence caches in this scenario is completely controlled by Hibernate. JVMs running the same Hibernate application to share a second-level cache. Using Coherence as a Hibernate second-level cache implementation allows multiple Therefore, we provide dedicated releases of the Hibernate Second-Level Cache implementationsįor Oracle Coherence depending on the Hibernate versions. The next couple of versions the SPI was further refined leading to breaking changes. September 11th 2008) the second-level cache SPI was significantly redesigned. Provider Interface (SPI) to be configured. Has incorporated second-level caching, by allowing an implementation of a Service Since version 2.1 (released December 11th 2003) Hibernate This page describes how you can use Oracle CoherenceĪs a second-level cache in Hibernate ORM, an object-relational mapping libraryįor Java applications.
