Recovering the Windows Registry

19-6 Oracle Fusion Middleware Administrators Guide You use the custom WLST command applyJRF to configure the Managed Servers or cluster with JRF. To use the custom WLST commands, you must invoke the WLST script from the Oracle Common home. See Section 3.5.1.1 for more information. The format of the applyJRF command is: applyJRFtarget={server_name | cluster_name | }, domainDir=domain_path, [shouldUpdateDomain= {true | false}] You can use the applyJRF command online or offline: ■ In online mode, the JRF changes are implicitly activated if you use the shouldUpdateDomain option with the value true which is the default. In online mode, this option calls the online WLST save and activate commands. ■ In offline mode, you must restart the Administration Server and the Managed Servers or cluster. In offline mode, if you specify the shouldUpdateDomain option with the value true, this option calls the WLST updateDomain command. For example, to configure the Managed Server server1 with JRF, use the following command: applyJRFtarget=server1, domainDir=scratchOracleMiddlewareuser_ projectsdomainsdomain1 To configure all Managed servers in the domain with JRF, specify an asterisk as the value of the target option. To configure a cluster with JRF, use the following command: applyJRFtarget=cluster1, domainDir=scratchOracleMiddlewareuser_ projectsdomainsdomain1

19.4 Creating Clusters

A WebLogic Server cluster consists of multiple WebLogic Server server instances running simultaneously and working together to provide increased scalability and reliability. A cluster appears to clients to be a single WebLogic Server instance. The server instances that constitute a cluster can run on the same computer, or be located on different computers. You can increase a clusters capacity by adding additional server instances to the cluster on an existing computer, or you can add computers to the cluster to host the incremental server instances. Each server instance in a cluster must run the same version of WebLogic Server. You can create a cluster of Managed Servers using WLST, the Oracle WebLogic Server Administration Console, or Fusion Middleware Control. This section describes how to create a cluster using Fusion Middleware Control.
