I would suggest always running in "Production Mode" on servers, even if they are development servers. It means you can adopt a single approach all the way through your development, test and production environments. The pages are broken down into several sections: Change Center : This is situated at the top-left of every page. Once the necessary changes are made, click the "Activate Changes" button and all modifications will be applied.

Duration: 30 minutes Oracle WebLogic Server 12c Machine definitions help WebLogic Server choose backup servers for session replication. Machine definitions also include WebLogic Node Manager configuration. This tutorial shows you how to create and configure machines by using the Oracle WebLogic Server 12c Duration: 30 minutes Configure and Use Node Manager In a production environment, WebLogic Server instances are often distributed across multiple domains, machines, and geographic locations.

Node Manager is a WebLogic Server utility that enables you to start, shut down, and restart the administration server and managed servers from a remote location. Although Node Manager is not required, it is recommended if your WebLogic Server environment hosts applications with high availability requirements. A Node Manager process is not associated with a specific WebLogic domain, but with a particular machine.

You can use the same Node Manager process to control server instances from any WebLogic Server domain, as long as those server instances reside on the same machine as the Node Manager process.

Duration: 15 minutes Oracle WebLogic Server 12c A cluster appears to a client as one WebLogic Server instance. Web application client requests go to the cluster proxy, which passes those requests to one of the servers in the cluster.

A cluster proxy can be a web server, a hardware load balancer, or even another instance of WebLogic Server itself. The managed servers that make up a cluster can run on the same machine or on different machines.

For increased reliability, managed servers in a cluster typically run on more than one machine. This tutorial shows you how to use the Oracle WebLogic Server 12c The data source has a collection of database connections called a connection pool. An application can request a connection from the data source, use the connection to access the database, and then close the connection.

Rather than actually close the connection, however, the data source places it back in the connection pool to be used again. Data sources can be created as part of the configuration of an instance of WebLogic Server. When that server comes up, or the data source is deployed , the server creates database connections to fill the connection pool of its data source.

Dynamic clusters consist of server instances that can be dynamically scaled up to meet the resource needs of your application.

A dynamic cluster uses a single server template to define configuration for a specified number of generated dynamic server instances. When you create a dynamic cluster, the dynamic servers are preconfigured and automatically generated for you, enabling you to easily scale up the number of server instances in your dynamic cluster when you need additional server capacity.

You can simply start the dynamic servers without having to first manually configure and add them to the cluster. If you need additional server instances on top of the number you originally specified, you can increase the maximum number of servers instances dynamic in the dynamic cluster configuration or manually add configured server instances to the dynamic cluster.

A dynamic cluster that contains both dynamic and configured server instances is called a mixed cluster. Duration: 20 minutes Oracle WebLogic Server 12c This is called on-demand scaling. Establishing policies that set the conditions under which a dynamic cluster should be scaled up or down and actions that define the scaling operations themselves.

When the conditions defined in the scaling policy occur, the corresponding scaling action is triggered automatically. Using the WLDF Policies and Actions component, you can write policy expressions that will automatically scale up or scale down a dynamic cluster. These policies will monitor one or more resources, such as memory, idle threads, and CPU.

When the configured threshold is met, the scaling action is triggered. Web application archives use the. This tutorial covers using the Oracle WebLogic Server 12c You learn how to start and run the application, redeploy an updated version of the application, and undeploy the application. Duration: 15 minutes.
