Configure Node Manager Configure Load Balancing Method for EJBs and RMIs

Setting up WebLogic Clusters 10-9 address is the IP address or DNS name for the Administration Server for the domain port is the listen port for the Administration Server for the domain 9. Enter the user name for the domain at the Enter username to boot WebLogic Server prompt. 10. Enter the password for the domain at the Enter password to boot WebLogic Server prompt. The command shell displays messages that report the status of the startup process. 11. To start another server instance in the cluster, return to step 6. Continue through step 10. 12. When you have started all Managed Servers in the cluster, the cluster startup process is complete.

10.2.4 Configure Node Manager

Node Manager is a standalone Java program provided with WebLogic Server that is useful for starting a Managed Server that resides on a different machine than its Administration Server. Node Manager also provides features that help increase the availability of Managed Servers in your cluster. For more information, and for instructions to configure and use Node Manager, see Node Manager Administrators Guide for Oracle WebLogic Server.

10.2.5 Configure Load Balancing Method for EJBs and RMIs

Follow the instructions in this section to select the load balancing algorithm for EJBs and RMI objects. Unless you explicitly specify otherwise, WebLogic Server uses the round-robin algorithm as the default load balancing strategy for clustered object stubs. To understand alternative load balancing algorithms, see Section 5.2, Load Balancing for EJBs and RMI Objects. To change the default load balancing algorithm: 1. Open the WebLogic Server Administration Console.

2. Select Environments Clusters.

3. Select the name of your cluster in the table.

4. If you have not already done so, click Lock Edit in the top left corner of the

Console. 5. Enter the desired load balancing algorithm in the Default Load Algorithm field.

6. Select Advanced.

7. Enter the desired value in the Service Age Threshold field Note: After you start a Managed Server, it listens for heartbeats from other running server instances in the cluster. The Managed Server builds its local copy of the cluster-wide JNDI tree, as described in Section 3.2.3, How WebLogic Server Updates the JNDI Tree, and displays status messages when it has synchronized with each running Managed Server in the cluster. The synchronization process can take a minute or so. 10-10 Using Clusters for Oracle WebLogic Server
