Portal Runtime 

Purpose

The Portal Runtime (PRT) provides a Java-based framework for running portal applications, which produce content for display in the portal.

The PRT is packaged as a J2EE Web application called the Enterprise Portal Base Component (EPBC).

The EPBC file contains three main parts:

●      Libraries and Configuration Files: PRT and its configuration

·        Core Applications:  Core PRT services. These applications are not stored in the PCD but are deployed on each server node. Core applications have the following characteristics:

○       Provide core functionalities, such as authentication and PCD.

○       Loaded before other applications when the portal is initialized.

○       Never loaded into the Application Repository.

·        Portal Applications: Basic portal applications shipped with the portal and stored in the Application Repository.

Regular applications are started only when required, either because the application is marked to be loaded on startup (by setting in the deployment descriptor) or because an element of the application has to be executed.

PRT Services

The PRT provides the following J2EE services:

·        Portal Runtime Container: Manages the following runtime processes:

○       Deployment of portal applications

○       Communication between portal applications and J2EE applications.

·        PRTBridge: Provides a link between portal runtime processes and the J2EE engine cluster configuration. It is installed as a J2EE engine service.

PRT Configuration

Portal Runtime settings can be configured to fine-tune its performance.
