![]() To use the GAR at runtime, the weblogic-application.xml deployment descriptor in an EAR must contain a reference to the GAR. For general information about shared libraries and their deployment, see "Creating Shared Java EE Libraries and Optional Packages" in Developing Applications for Oracle WebLogic Server. If the extend client tier is setup as a WebLogic Server cluster, deploy the EAR to the cluster and the WebLogic deployment infrastructure copies the module to each managed Coherence server.ĭeploying Coherence Applications as Shared LibrariesĪ standalone GAR can be deployed as a shared library and referenced by multiple EAR files. The client's cache configuration file must include a remote cache service definition that defines the address of a proxy server. If the application tier is setup as a WebLogic Server cluster, deploy the GAR to the cluster and have the module copied to each managed Coherence server.Įxtend Client Tier â Deploy the EAR that contains the extend client implementation (Web Application, EJB, and so on) as well as the GAR to each managed server that hosts the extend client. 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. Coherence is setup in tiers within a WebLogic Server domain.
