    Server template<\/h3>\n

    A server template defines a set of attributes. A change in a template will be propagated to all server depending on it. A dynamic cluster can be based on a server template.<\/p>\n

    Here is an overview of the configured to dynamic change:<\/p>\n

      \n
    1. Write down all customized parameters of server\u2019s member of the cluster.<\/li>\n
    2. Create new dynamic cluster<\/li>\n
    3. Report all settings. There are two specificities on dynamic cluster:\n
        \n
      1. Listen port and SSL port which can be either:\n
          \n
        1. Static<\/span>, meaning all servers of the cluster will have same port. This is the best option when you have one server to one machine mapping<\/li>\n
        2. Calculated, meaning each server will listen on a different port by step of 1. For example, if first port is set to 7000, server 1 will listen on 7001, server 2 on 7002, \u2026<\/li>\n<\/ol>\n<\/li>\n
        3. Machine binding: Use of a specific (filtered) subset of machines from the cluster<\/li>\n<\/ol>\n<\/li>\n
        4. Create new server template<\/li>\n<\/ol>\n

          [\/vc_column_text][vc_column_text]<\/p>\n

          Procedure<\/h3>\n
            \n
          1. In left tree, go in Environment, Clusters, Server Templates<\/li>\n
          2. Lock & Edit the configuration and click New\n
              \n
            1. Name the template:
              \n\"5<\/a><\/li>\n
            2. In the server template list, select the newly created template to customize the parameters.<\/li>\n
            3. In General tab, select the Cluster that needs to be converted:
              \n              \"6<\/a><\/li>\n
            4. Save<\/li>\n<\/ol>\n<\/li>\n
            5. In Environment, Clusters, Servers tab, set Server Template name:
              \n              \"Cluster<\/a><\/li>\n
            6. Save and Activate the changes<\/li>\n
            7. In Environment, Servers folder, dynamically created servers will be displayed (4 in your example):
              \n              \"7
              \n<\/a>Note that machine are distributed across available machines in round robin\u00a0and also the Listen port and SSL are incrementing.<\/li>\n
            8. Then, start these new servers, test application is running correctly.<\/li>\n
            9. Finally, stop configured managed servers by selecting “Work when completes”:
              \n              \"8<\/a><\/li>\n<\/ol>\n

              Cluster is now dynamic and you can easily add or remove managed servers from cluster.[\/vc_column_text][vc_column_text]<\/p>\n

              What Next ?<\/h3>\n

              This was a quick overview of how to convert configured to dynamic cluster. As we saw, it still require manual intervention to add or remove servers from cluster.<\/p>\n

              Coming with 12.2.1, WebLogic introduce a new feature called “elasticity”. This feature allows to automatically scales the amount of managed servers in the cluster based on user defined policies.<\/p>\n

              Thanks to WebLogic Diagnostic Framework (WLDF) Policies, it is possible to monitor memory, CPU usage, threads and then trigger a scale up or down action.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
