2, Oracle Portal architecture
1) Oracle Portal Node
Each server installing an Oracle Portal is called an Oracle Portal node. Each OraclePortal node contains more than 200 tables and views, and more than 1000 PL / SQL packages. The Oracle Portal node can be registered with each other to form a joint Portal structure. The registration and management of nodes can be easily managed by the central Portal of the company. Portal containers are places where Oracle Portal objects are stored. It saves the Provider registry, the page style definition, the user's customization, access, the content area, and the page definition, data-driven components, and the like. Database Provider management PL / SQL or Java storage process based on the database-based PL / SQL or Java stored in the portal node. The Portal framework calls these portlets via database Provider and display the result of the returned HTML / XML form on a area of the page. Different from the database Provider, the web provider is a data from the web, which is usually called through the HTTP protocol instead of the database store, and the resulting result is already formatted HTML / XML content.
