![]() The distribution algorithm minimizes network traffic and avoids service pauses by incrementally shifting data. ![]() Data is automatically, dynamically and transparently partitioned across nodes. Replicated Cache-Perfect for small, read-heavy caches.ĭistributed Cache-True linear scalability for both read and write access. ![]() Local Cache-Local on-heap caching for non-clustered caching. See Chapter 2, "Installing Coherence*Web on WebLogic Server 9.2 MP1 and 10.3.Coherence provides several cache implementations: SPI-based installation is available for versions 9.2 MP1, 10.3 and later. "General Instructions for Installing Coherence*Web Session Management Module" Table 1-1 Web Containers Supported by Coherence*Web Application Server The result of this tighter integration with WebLogic is simplified installation and deployment that no longer requires application instrumentation (using the WebInstaller).Ĭhapter 2, "Installing Coherence*Web on WebLogic Server 9.2 MP1 and 10.3," describes the SPI-based WebLogic Server implementation of Coherence*Web in more detail.Ĭhapter 5, "Installing Coherence*Web on WebLogic Portal," describes the SPI-based WebLogic Portal implementation of Coherence*Web in more detail.Ĭoherence*Web and other Application Serversįor WebLogic Server versions 10.3 and 9.2MP1, as well as other third-party application servers, Coherence*Web provides a generic installer that transparently instruments your Web applications.Ĭhapter 3, "Installing Coherence*Web on Other Application Servers," describes the implementation of Coherence*Web with WebInstaller in more detail. The current release of Coherence*Web integrates with WebLogic Server and WebLogic Portal versions 9.2 MP1 and 10.3 using the native WebLogic session management SPI. ![]() Using Coherence*Web with WebLogic Server and WebLogic Portal Supports fine-grained session and session attribute scoping by way of pluggable policies (see "Session and Session Attribute Scoping"). Provides advanced session distribution and lifecycle controls by way of the session distribution controller and reaper (see "Cleaning Up Expired HTTP Sessions"). Supports multiple advanced session models (that is, Monolithic, Traditional, and Split Session) which define how the session state is physically managed and serialized/deserialized in the cluster (see "Session Models"). Supports numerous portal containers, including Oracle WebLogic Portal (see Chapter 5, "Installing Coherence*Web on WebLogic Portal").Īllows for session state to be managed in the various caching topologies available in Coherence (that is, Replicated, Partitioned, Near Caching, Read-Through, Write-Through, Write-Behind and Refresh-Ahead Caching, and so on).Īllows storage of session data outside of the Java EE application server, freeing application server heap space and enabling server restarts without session data loss (see "Deployment Topologies"). Supports all of the mainstream application servers such as Oracle WebLogic Server, IBM WebSphere, Tomcat, and so on (see "Supported Web Containers"). Built on top of Oracle Coherence, Coherence*Web:Įnables session sharing and management across different Web applications, domains and heterogeneous application servers.īrings Coherence data grid's data scalability, availability, reliability, and performance to in-memory session management and storage. Coherence*Web is an HTTP session management module dedicated to managing session state in clustered environments.
