The cache configuration file packaged in the GAR must include a proxy service definition. Proxy Tier â Deploy the standalone GAR to each managed Coherence server of the proxy tier. If the application tier is setup as a WebLogic Server cluster, deploy the EAR to the cluster and have the module copied to each managed Coherence server. If the data tier is setup as a WebLogic Server cluster, deploy the GAR to the cluster and have the module copied to each managed Coherence server.Īpplication Tier â Deploy the EAR that contains both the client implementation (Web Application, EJB, and so on) and the GAR to each managed Coherence server in the cluster. For details on creating Coherence deployment tiers, see Administering Clusters for Oracle WebLogic Server.ĭata Tier â Deploy a standalone GAR to each managed Coherence server of the data tier. The following list describes how GAR modules are deployed in a WebLogic Server domain that uses Coherence tiers. GAR modules should be deployed as standalone modules and also as part of an EAR. For detailed instructions on the other deployment options, see Deploying Applications to Oracle WebLogic Server. For details on using WLST, see Understanding the WebLogic Scripting Tool. For details on using the WebLogic Server Administration Console, see Oracle WebLogic Server Administration Console Online Help. In this case, a Coherence application can be deployed to a single managed server and a single-server cluster is automatically created using default cluster settings.įor details on creating Coherence data tiers and setting up Coherence clusters for deployment, see Administering Clusters for Oracle WebLogic Server.ĭeploying Applications to the Coherence ContainerĬoherence application GAR modules get deployed the same way as JavaEE modules and can be deployed using any WebLogic Server deployment tool: the WebLogic Server Administration Console, the Oracle WebLogic Scripting Tool (WLST), the WebLogic Server Deployer class, and the WebLogic Server ANT target. However, managed Coherence servers in each tier can be individually managed as required.ĭuring development and simple testing, setting up Coherence deployment tiers may be impractical. The use of WebLogic Server clusters simplifies the deployment of an application and the management of the deployment topology, especially in large clusters. ![]() Coherence tiers are typically associated with respective WebLogic Server clusters. Managed servers that are part of a Coherence cluster are referred to as managed Coherence servers. The deployment tiers contain managed servers that are part of a Coherence cluster. The use of a dedicated storage tier that is separate from the application tier and proxy tier is a best practice that ensures optimal performance of a Coherence cluster. The tiers often include: a data tier for storing data an application tier for consuming cached data and a proxy tier for allowing remote clients (non cluster members) to use a cluster. The Coherence distribution includes a collection of examples that exercise many Coherence features.Coherence is setup in tiers within a WebLogic Server domain. Upgrading Coherence from Previous Releases If you are already working with Coherence, upgrade your applications to use the current release. Installing a Client Distribution, Installing Coherence*Web to an Application Server Post-configuration administration and configuration tasksĭiscover additional tools and resources to configure and administer Oracle Coherence. This transfers the software to your system. Run the installation program to install the software. Understanding the Oracle Coherence Directory Structure Verify that the directory into which you want to install Oracle Coherence is accessible by the installer, and exists on systems that meet the minimum requirements. Understanding and Obtaining the Oracle Coherence Distribution ![]() To install Oracle Coherence, obtain the distribution. ![]() Roadmap for Verifying Your System Environment and System Requirements Table 1-1 Roadmap for Standalone Oracle Coherence Installation Taskīefore beginning the installation, verify that the minimum system and network requirements are met.
