![]() ![]() Documentation for configuring the WebLogic Server proxy plug-in is available here:Ģ.2 Configuring And Deploying Coherence*Web on WebLogic Server-Main StepsĬoherence*Web includes a deployable shared library that contains a native plug-in to WebLogic Server's HTTP Session Management interface. WebLogic Server ships with several different proxy plug-ins which enforce JVM session stickiness. The default load balancer enforces HTTP session JVM affinity, however, other load balancing alternatives are available. However, you will require a load balancer if you employ sticky session optimization with any of the non-Optimistic locking modes. See "Session Locking Modes" for more information about locking modes.īy itself, the Coherence*Web SPI does not require a load balancer to run in front of the WebLogic Server tier. This allows concurrent access to a session by multiple threads in a single JVM or multiple JVMs while prohibiting concurrent modification. Both Coherence*Web and the Coherence*Web SPI employ Optimistic locking by default. Enter any cache configuration changes in the session-cache-config.xml file and then repackage it in the coherence-web-spi.war file.Ĭoherence*Web provides several session locking modes to control concurrent access of sessions. This file is located in the coherence-web-spi.war file under the WEB-INF\classes directory. ![]() The session-cache-config.xml file contains the Coherence cache configurations used by the Coherence*Web SPI. If a request to the cache server has not responded in 30 seconds, a exception is thrown. The timeout for requests to the cache server to respond is 30 seconds. This means a Coherence cache server must be running in its own JVM, separate from the JVM running WebLogic Server. The server will serve requests and will not be used to host data. The Coherence*Web SPI for WebLogic Server is configured with local-storage disabled. The fact that cache operations are being sent and executed on a remote cluster node (over TCP/IP) is completely transparent to the client application.In Coherence*Web, the following default cache configurations are defined: Once it is obtained, a client accesses the INamedCache in the same way as it would if it were part of the Coherence cluster. This library sends all client requests to the Coherence*Extend clustered service which, in turn, responds to client requests by delegating to an actual Coherence clustered service (for example, a Partitioned or Replicated cache service).Īn INamedCache instance is retrieved via the CacheFactory.GetCache() API call.

Since its initial release in 2001, it has been used by thousands of customers across many industries to power some of the mission critical systems you use every day.
