A cluster is a set of WebLogic servers working together, serving pages at the same port. From the user’s point of view, all of the servers function as a single server; it does not matter which server handles a given request.
Virtually all production sites use clustering. Clustering provides much better performance and reliability than running on a single server. For example, if one server in a cluster goes down, the user may not be aware of it, because the other servers in the cluster can take over the sessions it was handling.
Setting up clustering of WebLogic servers running Oracle Commerce Platform applications involves the following steps:
Create a group of WebLogic servers for serving pages, and assign them to a cluster.
Create additional WebLogic servers for the Oracle Commerce Platform lock manager, process editor server, workflow process manager and any other services that require a dedicated server. Assign these servers to a different cluster from the page servers.
For each WebLogic server, create a corresponding Oracle Commerce Platform server configuration.
Assemble your Oracle Commerce Platform application, and deploy it on each WebLogic server in both clusters. Configure the application on each WebLogic server to use the Oracle Commerce Platform server configuration that corresponds to that server.
See the Oracle WebLogic documentation for information about creating WebLogic servers and clusters. For information about creating Oracle Commerce Platform server configurations, see Creating Additional Oracle Commerce Platform Server Instances.
