java - WebLogic Server 域是什么以及它有什么作用？

Question

我是一名 Java 开发人员，我在使用 Java 进行 Web 应用程序开发方面还很陌生，我有以下疑问。

我们正在开发部署在 Oracle WebLogic Server 上的网络应用。

weblogic 域到底是什么？据我了解，每个应用程序都使用定义的域。但它到底做了什么？

Answer 1

来自甲骨文 documentation :

A domain is the basic administrative unit of WebLogic Server. It consists of one or more WebLogic Server instances, and logically related resources and services that are managed, collectively, as one unit.

所以它是一个管理容器，您应该考虑以下几点:1 个域等于 1 个管理服务器。

管理服务器:

A domain includes one WebLogic Server instance that is configured as an administration server. All changes to configuration and deployment of applications are done through the administration server.

The administration server provides a central point for managing the domain and providing access to the WebLogic Server administration tools. These tools include the following:

• WebLogic Server Administration Console: Graphical user interface to the administration server.

• WebLogic Server Node Manager: A Java program that enables you to start and stop server instances—both administration servers and managed servers—remotely, and to monitor and automatically restart them after an unexpected failure.

• Note that the node manager is installed on all the machines that host any server instance – both administration server and managed servers.
