![]() When you restart your node it will join the cluster and your data will be there. Keep in mind that often you have more than one coherence node in the cluster so you will not lose your data when you shutdown one of them because data is always stored also in other JVM(s). This is described here in the documentation. If you need to manage data in persistent store you can look into CacheStore interface. In general coherence is in memory solution and doesn't persist data by default. Start your WLS with the following option: =custom-cache-config.xmlĭeploy and start your application (possibly on many servers) Otherwise put the following to your custom-cache-config.xml file and add it to your application's classpath.Ĭreate a ContextListener for your application and place the following code into contextInitialized method: // join existing cluster or form a new one You can skip this step if you want to use coherence default cache configuration coherence-cache-config.xml which includes replicated topology, but keep in mind that your cache name must start with repl- and this is in general not recommended for production. Coherence defines a distributed cache as a collection of data that is distributed across any number of cluster nodes such that exactly one node in the cluster is responsible for each piece of data in the cache, and the responsibility is distributed (or, load-balanced) among the cluster nodes. Prepare your own cache configuration for the replicated topology. It describes how to develop applications for the Oracle Coherence data. ![]() It also has other advantages like easier maintenance. This tutorial is intended for software developers, architects, and administrators. Unless you want to share coherence node between many applications it is often a better idea to put it to application's classpath. Depending on specific case it can be WLS classpath or application's classpath. CoherenceRx introduces ObservableMapListener, which extends RxJava Observable and implements Coherence MapListener interface. N95-24040 Tutorial on filtering, restoration, and state estimation TR. Oracle Coherence provides rich event notification functionality, so it only made sense to provide an adapter that allows you to use RxJava to process stream of event notifications.
