Explanation:

Detailed explanation-1: -If you create the domain in development mode, the wizard saves the username and encrypted password in a boot identity file. A WebLogic Server instance can refer to a boot identity file during its startup process. If a server instance does not find such a file, it prompts you to enter credentials.

Detailed explanation-2: -High Availability: High Availability is achieved in the WebLogic server by a combination of the following features-Failover, Replication, and also with the migratable services. With these, we can use WebLogic seamlessly without worrying even when a participating node is down or unavailable.

Detailed explanation-3: -Node Manager is a Java utility that runs as separate process from WebLogic Server and allows you to perform common operations tasks for a Managed Server, regardless of its location with respect to its Administration Server.

Detailed explanation-4: -Log in by using the administrative credentials (user name and password) that you used when you created the WebLogic domain. In the Domain Structure menu, click Deployments and then click Install in the Deployments section. In the Install Application Assistant, specify the name of the application archive file for Path.
