![]() ![]() If your application is in an EAR file, then the packaging for the custom session-cache-config file has changed in 12 c (12.1.2). If you created a custom session-cache-config.xml, you should be able to leave the file name as it is. You should not have to change the session cache file name. =session-cache-config.xmlĬhange it to default-session-cache-config.xml in 12 c (12.1.2): x application, note that the name has been changed to default-session-cache-config.xml in 12 c (12.1.2).įor example, if you used this context parameter value in Coherence release 3.7.1. If you used the default session-cache-config.xml file in your Coherence release 3.7.1. Modify your applications to use the required settings for Coherence 12 c (12.1.2): Remove any explicit references to the coherence.jar file in the classpath. In the META-INF/MANIFEST.MF file, remove the following lines that identify Coherence as an extension: In the weblogic.xml file, remove the element that refers to the coherence-web-spi file. Modify your applications to remove all references to the coherence.jar file: For information on upgrading WebLogic Server, see Oracle Fusion Middleware Upgrading Oracle WebLogic Server. Undeploy the coherence.jar and coherence-web-spi.war files if they are deployed.įollow the steps to upgrade WebLogic Server and its domains to WebLogic Server 12 c (12.1.2). Stop and undeploy the applications that use Coherence*Web. To align Coherence log output with Helidon logging format.3.1 Upgrading Applications Using Coherence and Coherence*Web on WebLogic Serverįollow these instructions for upgrading applications running on WebLogic Server that use Coherence and Coherence*Web. We add Coherence MicroProfile Config as a dependency, which allows us to configureĬoherence using Helidon MP Configuration and changes Coherence logging defaults Is started within Helidon application via CDI extension. We add Coherence CDI Server as a dependency, which ensures that Coherence server This ensures that all necessary Helidon dependencies are imported correctly. We add Helidon MicroProfile bundle and JSON Binding support as dependencies. ![]() The parent POM is set to io.helidon.applications:helidon-mp and The pom.xml file is a good starting point for Helidon microservices Think of it as stored procedures, but using Java lambdas and rich server-side domain models. ![]() This can not only significantly impact how much data needs to be moved over the wire, but it also takes care of cluster-wide concurrency control - each entry processor has the exclusive access to the entry it is processing for the duration of its execution. Read-modify-write is probably the most common data access pattern in vast majority of applications, even though it is very inefficient way of performing data modification.Ĭoherence addresses this problem by allowing you to send the data modification code into the grid and execute it where the data is, against one or more entries. The problem with many applications that both hurts their performance and prevents them from scaling is that they simply move too much data over the network and require complicated distributed concurrency control. If there is one defining feature that makes Coherence stand out from many competing technologies, and allows you to write efficient distributed applications, this is it. ![]()
