![]() The Coherence release number: Oracle Coherence 3.6.0.0. The default is to load from JAR: Loaded operational configuration from resource "jar:file:/C:/oracle/product/coherence/lib/coherence.jar!/tangosol-coherence.xml" Information about how configuration files are loaded. Several important features are highlighted in the example: On start-up, the cache server produces output similar to the text in Example 1-2. ![]() When it determines that there are no clusters to join, it starts one. When you start the first cache server, there is a slight delay because the cache server looks for an existing cluster.

Navigate to the directory where Coherence is installed. Include JAVA_HOME\bin in the PATH environment variable. Set the JAVA_HOME environment variable to the base of the JDK installation. If the PATH environment variable does not include the JDK \bin directory, then set it as follows: Open a terminal window and verify that the PATH environment variable is set to include the Java JDK (for example, \oracle\product\jdk160_14_R27.6.5-32\bin). It is much like a database server, but without the requirement for storage.Ĭonfigure and Run the Sample Cache Server ApplicationĬonfigure and Run the Sample Cache Client ApplicationĮxercise the Sample Cache Client Applicationġ.3.1 Configure and Run the Sample Cache Server Applicationįollow these steps to set up and run the sample cache server application. The purpose of a Coherence cache server is to manage application state in a cluster outside the application process. To manage objects in this way, Coherence uses "cache servers". This allows objects to survive possible application outages (either deliberate or accidental). However, to increase the availability of the objects, Coherence may manage objects in-memory but out of the application process. When an application uses Coherence out-of-the-box, objects placed into Coherence caches are typically stored and managed in-process within the application. ![]() By executing these applications on either a single host or several hosts, you can determine whether Coherence is operating correctly locally or across a network. It also provides information about the cluster. The "cache client," is a simple application that enables a developer to access, process, and update cached data within a cluster. The " cache server," is a simple application that hosts and manages data on behalf of other applications in a cluster. ( localhost is the local IP address and not the loop back address.)Ĭoherence ships with two simple command-line (shell-based) applications that can be used to determine whether Coherence operates correctly. Inter-process communication between cluster members. Designing the address in this way ensures that different versions of Coherence do not inadvertently cluster with each other by default. For example, for the 3.6.0.0 release, the port number would be 36000. ![]() The port number also reflects the release version. ![]() For example, the multicast address for the 3.6.0.0 release would be 224.3.6.0. The variable version represents the release version of Coherence. Table 1-1 Network Addresses and Ports Used by Coherence Address / Port / TypeĬluster member discovery and broadcast. ![]()
