            Overview<\/h2><\/span>\n

            Prepare Environment<\/h3><\/span>\n

            * Decide on cluster architecture (basic vs multi tier, proxy or not)
            \n* Network and security
            \n* Firewalls
            \n– don’t cluster over firewalls
            \n* Choose machines
            \n* IP addresses and DNS names, port numbers
            \n* Configure node manager<\/p>\n

            Tools to Configure Cluster<\/h3><\/span>\n

            * Configuration wizard
            \n* Admin console
            \n* JMX: weblogic.management.configuration.ClusterMBean<\/em>
            \n* weblogic.Server<\/em> API
            \n* WLST<\/p>\n

            Start Cluster<\/h3><\/span>\n
            * Start individual managed server instances
            \n* For example:
            \n– Start MyMSvr1:<\/p>\n
            \r\n.\/startManagedServer MyMSvr1\r\n<\/pre>\n
            – Start MyMSvr2 (from another command window):<\/p>\n
            \r\n.\/startManagedServer MyMSvr2\r\n<\/pre>\n
            \"\"<\/a><\/h6><\/span>\n
            Configure OHS as the cluster proxy server<\/h2><\/span>\n
            * Relies on mod_wl_ohs<\/em>
            \n* Uses WebLogicCluster<\/em> directive to configure a cluster<\/p>\n
            \r\nLoadModule weblogic_module \"${ORACLE_HOME}\/ohs\/modules\/mod_wl_ohs.so\"\r\n\r\n\r\n    WebLogicCluster w1s1.com:7021,w1s2.com:7021,w1s3.com:7021\r\n    ErrorPage http:\/\/myerrorpage.mydomain.com\r\n    MatchExpression *.jsp\r\n<\/IfModule>\r\n\r\n\r\n    SetHandler weblogic-handler\r\n<\/Location>\r\n<\/pre>\n
            Start and Stop OHS Manually<\/h3><\/span>\n
            \r\n# Check status\r\n.\/opmnctl status -l\r\n\r\n# Start\r\n.\/opmnctl stopproc process-type=OHS\r\n\r\n# Stop\r\n.\/opmnctl startproc process-type=OHS\r\n\r\n# Restart\r\n.\/opmnctl restartproc process-type=OHS\r\n<\/pre>\n
