Loaded operational configuration from "jar:file:/C:/Oracle/Middleware/Oracle_Home/coherence/lib/coherence.jar!/tangosol-coherence.xml" The default is to load from the coherence.jar file: 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 the cache server 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. %java_exec% -server -showversion %java_opts% -cp "%coherence_home%\lib\coherence.jar" =3155 %1Įxecute the cache server application that is located in the coherence\bin folder.Ĭ:\oracle\product\coherence\bin>cache-server.cmd Set java_opts=-Xms%memory% -Xmx%memory% %jmxproperties% If "%java_home%"="" (set java_exec=java) else (set java_exec=%java_home%\bin\java) If not exist "%coherence_home%\lib\coherence.jar" goto instructions Navigate to the folder where Coherence is installed.Ĭd C:\oracle\Middleware\Oracle_Home\coherence\binĮdit the cache-server.cmd file to set the COHERENCE_HOME environment variable to point to the Coherence installation folder:Ĭoherence_home=C:\oracle\Middleware\Oracle_Home\coherenceĮxample 1-1 illustrates the cache-server.cmd file with the edited value of the COHERENCE_HOME environment variable.Įxample 1-1 cache-server.cmd File with an Edited This will start a cache specify the Coherence installation directory Include JAVA_HOME\bin in the PATH environment variable.

If the PATH environment variable does not include the JDK or JRE \bin folder, then set it as follows: Open a terminal window and verify that the PATH environment variable is set to include the Java JDK or JRE (for example, C:\Oracle\Middleware\Oracle_Home\jdk1.7.0_25\bin). To set up and run the sample cache server application: It is similar to a database server, but without the requirement for storage.ġ.3.2 Configure and Run the Sample Cache Server Application The purpose of a Coherence cache server is to manage the application state in a cluster outside the application process. To manage objects in this way, Coherence uses cache servers. This enables objects to survive possible application outages (either deliberate or accidental). However, to increase object availability, Coherence can manage objects in memory but out of the application process. When an application uses Coherence as shipped, objects placed into Coherence caches are typically stored and managed in-process within the application. By executing these applications either on a single host or on 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. The default port of the IpMonitor component that is used for detecting hardware failure of cluster members is "7".Ĭoherence ships with two simple command-line (shell-based) applications that can be used to determine whether Coherence operates correctly. By default, the port is assigned as the next available port after the first unicast port. ( localhost is the local IP address and not the loop back address.)Īn additional port that is used for unicast communication. Interprocess communication between cluster members. Designing the address in this way ensures that different versions of Coherence do not cluster with each other by default. For example, for the 12.1.3 release, the port number is 12100. The port number also reflects the release version. For example, the multicast address for the 12.1.3 release is 224.12.1.0. The variable version represents the release version of Coherence.
